Abstract:
In this paper, buffer capacity profiles are used in the framework of automatic monitoring of water quality. The aim of the proposed methodology is to automatically and stepwise build buffer capacity models for each particular titrated sample, and to quantify the individual buffer systems that constitute the total buffer capacity. An automatic and robust model building algorithm has been developed and applied to many titration curves of effluent and river water samples. It is illustrated that the application of automatically built buffer capacity models mostly results in similar or better estimations of ammonium and ortho-phosphate in the samples compared to a priori fixed buffer capacity models. The automatic modelling approach is also advantageous for alarm generating purposes on e.g. river waters, because unexpected buffers are easily detected.

Abstract:
This study aims to provide a process for the development of a train collision model that can evaluate the performance of buffers in the coupling system of railway vehicles. The model development process is completed by testing the buffer systems, analyzing the test results, and generating empirical models based on the analyzed results. In the analysis, it is shown that the behavior of the rubber buffer and the high-capacity buffer is well reproduced by the empirical models. A simulation model developed from the process is not only able to produce response behaviors of the buffers that are close to the test results, but is also able to estimate the maximum energy within a 2% error for the rubber buffer and a 4% error for the high-capacity buffer. The validated model can be used in extended systems – when multiple trains are connected through buffer systems – to evaluate the applied force or the absorbed energy on buffer systems, to optimize the configuration of the coupling systems or to evaluate the performance of the buffers under different collision conditions.

Abstract:
The soil Zn buffer capacity is an important factor that regulates the concentration of plant-available Zn in soil solution. It is measured variously as Zn buffer power, Zn sorption or Zn desorption capacity. This study was conducted to determine Zn buffer power, and Zn sorption capacity and Zn desorption capacity in Vertisols as influenced by soil properties. The Zn buffer power, defined as the slope of the line relating soil solution Zn concentration to DTPA-extractable Zn, varied from 217 to 790. Soil pH was found to be the major soil parameter responsible for the variation in Zn buffer power. The sorption of Zn by these Vertisols was satisfactorily described by the Freundlich equation. The calculated values of the Freundlich parameters were closely related to the soil pH and amorphous Al and Fe content. Desorption of Zn by a series of successive extractions with DTPA was described by the Mitscherlich equation. The calculated values of desorption capacity were negatively correlated with soil pH and positively correlated with the contents of Al and Fe oxides. Work published elsewhere showed that the parameters of both the Zn buffer power and Zn desorption capacity accounted for as much as 62% of the variation in relative yield of wheat from Zn application to Vertisols.

Abstract:
Abstract In this article, it is described how the reconfigurable inter-operational buffers system built on the Digital Twin platform. Interoperating production buffers are now widely used in production. Their effect on the production system can be seen in decreasing downtime. From a cost-based point of view, the interoperating production buffers may generate a gain from the reduction in the volume of work-in-process, with which we increase production performance. This ratio depends on the average number of products that the buffers contain. The average number of pieces in the buffer is limited by the capacity of the buffer. The impact of turbulence in production is seen precisely on the average content of inter-operational production buffers. If we want to maintain work-in-process on optimal values, it is necessary to calculate and maintain the optimal capacity of each interoperating production buffer on the line. In the context of Smart Factory, it is currently possible that the current capacity of the interoperating production buffers is maintained according to the current state of production. In the subject system, real production facilities communicate with each other through the IoT as autonomous agents, which are decided on the basis of a formula to calculate the optimal capacity of the buffers, the prediction of faults and negotiation, thus actively maintaining the optimal capacity of intermediate operating production buffers for Smart Factory support.

Abstract:
[ Truncated abstract] The purpose of this series of studies was to further our understanding of the relationship between muscle buffer capacity and training. Study one was performed to determine if there were differences in muscle buffer capacity (βmin-vitro) between females of differing training status (i.e., team-sport, endurance-trained and untrained subjects). Studies two and three were then performed to determine if short-term training could improve muscle buffer capacity and what type of training best improves this muscle characteristic (i.e., high-intensity, moderate-intensity or resistance training). Studies four and five were performed to determine if the accumulation of H+ during exercise was a mechanism by which training improved muscle buffer capacity. Below is a summary of these five studies. Study 1. The team-sport group had a significantly higher βmin-vitro than either the endurance-trained or the untrained groups (181 ± 27 v 148 ± 11 v 122 ± 32 'mol H+?g dm-1?pH-1 respectively; P<0.05). The team-sport group also completed significantly more relative total work (299 ± 27 v 263 ± 31 v 223 ± 21 J?kg-1, respectively; P<0.05) and absolute total work (18.2 ± 1.6 v 14.6 ± 2.4 v 13.0 ± 1.9 kJ, respectively; P<0.05) than the endurance-trained or untrained groups during a repeated sprint ability (RSA) test. There was a significant correlation between βmin-vitro and RSA (r=0.67; P<0.05). These findings show that young females competing in team sports have a larger βmin-vitro than either endurance-trained or untrained females. This may be the result of the intermittent, high-intensity activity during training and the match play of team-sport athletes... Conclusions. Our results show that training intensity is an important determinant of muscle buffer capacity. High-intensity interval training (120-150% LT) improved muscle buffer capacity (9 27%), however, neither moderate-intensity or resistance training improved muscle buffer capacity. In contrast higher training intensity (150-180% LT) may negatively affect muscle buffer capacity. Differences in the accumulation of H+ during high-intensity interval training does not appear to be the underlying mechanism for changes to muscle buffer capacity, however changes to this muscle characteristic were associated with pre-training muscle buffer capacity.

Abstract:
An accurate estimation of physiological buffer capacity and total titratable buffer concentration of blood can give a great deal of insight into the physiological stability of a patient and yet it remains an undervalued diagnostic marker. This thesis highlights the need for a lab-on-chip device to quantify buffer capacity of whole blood samples by estimating the total titratable buffer concentration. Buffer capacity is quantified by titrating the buffer to its end point using monoprotic acids. More sophisticated ways include electrolytic titration, i.e. producing a proton flux using electrodes in a controlled environment. This thesis looks at a novel approach to electrolytic (coulometric) titration by inhibiting the production of OH ions during electrolysis and titrating the sample due to the proton flux from the anode. By definition, is the amount of acid or base added to change the pH of 1 litre of buffer by 1 pH unit. The carbonic acid bicarbonate buffer system is the most important buffer that maintains the body's pH within a stable range. To quantify this buffer's total buffering concentration, it is important to know and indicate its titration end point which signifies the total exhaustion of all buffering constituents. Colorimetric indicators have been used to indicate this end point which can be quantified through cameras or spectrophotometric techniques. Using this novel coulometric titrator and the colorimetric end point detector, this thesis presents a portable lab-on-chip prototype to spectrophotometrically quantify total titratable buffer concentration. Clinically, this device could benefit patients with sickle cell disease, nephritic disease and those admitted in accident and emergency wards. This research work is aimed at presenting a proof-of-concept for a device that can titrate nano-litre samples and be able to detect the end point of a titration in a controlled way.

Full text
Abstract:
The concept of soil buffer capacity was used in this study to investigate the capacity of soil to attenuate heavy metals when acid is involved in the soil system. The buffer capacity of soil in this study was found to depend mainly on carbonate content and cation exchange capacity (C.E.C.) of soils. The magnitude of buffer capacity followed the order: illite $>$ montmorillonite $>$ natural clay soil $ gg$ kaolinite.
The study of heavy metal retention in soils was performed both by soil suspension test and soil column test. The results showed that as soils received increasing amounts of acid, high amounts of heavy metals (particularly Pb and Cu) could still be retained if the soils had a high enough buffer capacity to resist a change in pH such that it will not drop to $ Cu > Zn > Cd.$ The order changed to $Pb > Cd > Zn > Cu$ when soils were at low soil solution pH. Relative mobility of heavy metals found from the soil column test followed the order $Pb < Cu < Zn leq Cd.$
The relation of soil buffer capacity and heavy metal retention and movement in the clay soils found from this study revealed that the soil buffer capacity was a parameter that can be used in the prediction and prevention of heavy metal migration in soil. The soil buffer capacity is recommended as a parameter that should be included in the determination of soil properties particularly for the purpose of land application and disposal of wastes with leachates that could contain heavy metals.

ENGLISH ABSTRACT: To maximise the throughput of a production system the capacity constrained resource needs to be protected from variation and uncertainty. In the Theory of Constraints philosophy such protection is provided by means of time buffers and protective capacity. Time buffers are protective time that is allowed in the production schedule to buffer against disruptions, whereas protective capacity is defined as a given amount of extra capacity at non-constraints above the system constraint's capacity. In this research an analytical procedure was developed to more accurately determine the required time buffer lengths. This procedure uses an open queuing network modelling approach where workstations are modelled as GIIG/m queues. A simulation experiment was performed to evaluate the time buffer estimation procedure on the operations of an actual fifteen station flow shop. The results from the study suggest that the analytical procedure is sufficiently accurate to provide an initial quick estimate of the needed time buffer lengths at the design stage of the line. This dissertation also investigated the effect of protective capacity levels at a secondary constraint resource as well as at the other non-constraint resources on the mean flow time, the bottleneck probability of the primary constraint resource, as well as the output of flow production systems using simulation models and ANOV A. Two different types of flow production systems were investigated: (1) a flow shop with a fixed number of stations and unlimited queue or buffer space between stations, and (2) an assembly line where a total work content is distributed among stations in a certain fashion and the number of stations are not fixed. The experimental studies show that flow shop performance in the form of flow time and line output is not that much influenced by low protective capacity levels at the secondary constraint resource. Low protective capacity levels at a single station however can significantly reduce the bottleneck probability for the primary constraint resource when it is located before and relatively close or near to the primary constraint in the process flow, or after but relatively far from the primary constraint. An after-far secondary constraint location also causes slightly longer job flow times, and should therefore be avoided if possible. The research further shows that quite high protective capacity levels at the nonconstraint resources are needed to ensure a more stable and therefore manageable primary constraint. However low average levels of protective capacity at non-constraint resources are sufficient to ensure that the maximum designed output level as determined by the utilisation of the primary constraint resource is obtained. The results for the assembly line experiment showed that an unbalanced line configuration where less work is assigned to the non-constraint stations than to the primary constraint station (but nonconstraint stations have an equal work content) can lead to significant reductions in the mean flow time while maintaining the same line output, without resulting in too many additional stations. Low protective capacity levels in the range of 2% to 5% are sufficient to cause substantial improvements in flow time without resulting in too many additional stations in the line.
AFRIKAANSE OPSOMMING: Om die finale uitset van 'n produksiestelsel te maksimeer is dit noodsaaklik dat die bottelnek beskerm word teen fluktuasies en onderbrekings. In die "Theory of Constraints" filosofie word van twee soorte beskermingsmeganismes gebruik gemaak: tydbuffers en beskermende kapasiteit. Tydbuffers is beskermende tyd wat in die produksieskedule gevoeg word om sodoende die bottelnek teen onderbrekings te beskerm, terwyl beskermende kapasiteit ekstra produksiekapasiteit relatief tot die bottelnek se kapasiteit is wat by nie-bottelnekke gevoeg word. In hierdie navorsing IS 'n analitiese prosedure ontwikkel om meer akkurate berekenings van tydbuffergroottes te verkry in produksiestelsels wat volgens 'n "Theory of Constraints" filosofie bestuur word. Die prosedure maak gebruik van oop toustaan netwerk modellering waar werkstasies gemodelleer word as GIIG/m toue. Die analitiese prosedure is ge-evalueer met 'n simulasie eksperiment op 'n werklike vyftien stasie vloeiwinkel. Die resultate dui aan dat die analitiese prosedure akkuraat genoeg is om vinnig aanvanklike beramings vir die benodigde tydbuffergroottes tydens die ontwerpsfase van die produksiestelsel te verskaf. Verder is ook ondersoek ingestel na die effek van beskermende kapasiteitsvlakke by die sekondêre bottelnek asook die ander nie-bottelnekke op die gemiddelde deurvloeityd, die totale uitset, asook die bottelnek waarskynlikheid vir die primêre bottelnek in vloei produksiestelsels deur gebruik te maak van simulasie modelle en ANOVA. Twee verskillende tipes vloei produksiestelsels is ondersoek: (1) 'n vloeiwinkel met 'n vaste aantal stasies en 'n onbeperkte buffer spasie tussen stasies, en (2) 'n monteerlyn waar 'n totale werksinhoud op 'n bepaalde wyse onder stasies verdeel moet word en die aantal stasies nie vas is nie. Die eksperimentele studies dui aan dat die deurvloeitye en totale uitset van 'n vloeiwinkel me noemenswaardig beïnvloed word deur lae beskermende kapasiteitsvlakke by die sekondêre bottelnek nie. Hierdie maatstawwe word meer beïnvloed word deur die gemiddelde beskermende kapasiteitsvlakke by al die nie-bottelnekke. Lae beskermende kapasiteit by 'n enkele werkstasie kan egter die bottelnek waarskynlikheid vir die primêre bottelnek aansienlik verlaag indien dit voor en relatief na aan die primêre bottelnek in die prosesvloei geleë is, of na, maar relatief ver, vanaf die primêre bottelnek. 'n Sekondêre bottelnek ligging na maar relatief ver vanaf die primêre bottelnek in die prosesvloei veroorsaak ook langer deurvloeitye, en moet dus vermy word. Verder dui die navorsing aan dat redelike hoë gemiddelde beskermende kapasiteit by nie-bottelnekke benodig word om 'n meer stabiele primêre bottelnek te verseker. In vloeiwinkels met lae vlakke van variasie en onderbrekings is egter lae gemiddelde vlakke van beskermende kapasiteit by nie-bottelnekke voldoende om te verseker dat die maksimum ontwerpte uitset soos bepaal deur die benutting van die primêre bottelnek behaal word. Die resultate vir die monteerlyn eksperiment dui aan dat 'n ongebalanseerde lynkonfigurasie waar minder werk aan die nie-bottelnek stasies as aan die primêre bottelnek stasie toegeken word (maar niebottelnek stasies het 'n gelyke werksinhoud), aansienlike verlagings in deurvloeityd teweeg kan bring terwyl dieselfde lyn uitset behou word. Dit is moontlik sonder te veel addisionele stasies in die lyn. Die eksperimentele resultate dui aan dat lae beskermende kapasiteitsvlakke van tussen 2% tot 5% voldoende is om beduidende verlagings in deurvloeityd teweeg te bring sonder te veel addisionele stasies.

Abstract:
Hand rearing infants has always carried a greater mortality rate than breast feeding despite the development of safe preserving techniques for milk: stool bacterial culture revealed two distinctive florae, fermentatitive, with a predominance of lactobacilli in breast fed infants and putrefactive, with a predominance of coliform bacteria in artificially fed infants. This difference was suggested to be the basis for the difference in the incidence of gastroenteritis. An artificial milk inducing a breast milk stool flora would, thus, reduce the incidence of gastroenteritis in artificially fed infants. The buffer capacity of milk was claimed to determine stool buffer capacity, which then encouraged growth of specific bacterial populations. However, an artificial milk with identical buffer capacity to breast milk returned disparate bacterial results. The hypothesis examined in this study was that buffer capacity of infant milk modifies stool flora. Breast milk and three artificial milks were studied. The artificial milks differed either in buffer capacity or in composition of major dietary components. Biochemical analyses were performed on milk, stool and stool water obtained by ultracentrifugation. Buffer capacity in milk was related to protein content. No biochemical differences were detected in stool water from each group, however whole stool buffer capacity was considerably greater in the group fed high buffer capacity milk than in the other three groups. No difference was detected in total bacterial numbers cultured, the types of organisms, nor individual species numbers. Thus the presently available highly modified artificial milks may determine stool buffer capacity, but do not induce a gut flora distinct from breast feeding. Thus the continuing increased incidence of gastroenteritis in artificially fed infants can no longer be related to differences.

Many reactions in solution involve acids and bases, and so this chapter examines these important reactions in detail. Topics covered include the ionisation of water, pH, pOH, acids and bases, conjugate acids and conjugate bases, acid and base dissociation constants, the Henderson-Hasselbalch equation, the Henderson-Hasselbalch approximation, buffer solutions and buffer capacity. A unique feature of this chapter is a ‘first principles’ analysis of how a reaction buffered at a particular pH achieves an equilibrium composition different from that of the same reaction taking place in an unbuffered solution. This introduces some concepts which are important in understanding the biochemical standard state, as required for Chapter 23.

Abstract:
In this chapter, the hypothesis is explored that parenting processes buffer children’s physical health from the deleterious effects of discrimination. First, the existing empirical literature is reviewed on the stress-buffering effects of parenting on children’s physical health outcomes, with respect to the stress of general childhood adversity and the specific stressor of discrimination. Next, theoretical approaches are considered that account for the capacity of parenting to buffer contextual stressors, including discrimination, from compromising mental and physical health outcomes. Particular emphasis is given to the putative mechanisms potentially responsible for protective-stabilizing effects. Then, a critique of the extant research and theory on this topic highlights particular qualifications and considerations for the research community. Finally, suggestions are offered for future research directions, including the use of randomized prevention trials to test hypotheses about the protective functions of parenting in preventing discrimination from “getting under the skin.”

Abstract:
Humans have understood the importance of climate to human health since ancient times. In some cases, the connections appear to be obvious: a flood can cause drownings, a drought can lead to crop failure and hunger, and temperature extremes pose a risk of exposure. In other cases, the connections are veiled by complex or unobserved processes, such that the influence of climate on a disease epidemic or a conflict can be difficult to diagnose. In reality, however, all climate impacts on health are mediated by some combination of natural and human dynamics that cause individuals or populations to be vulnerable to the effects of a variable or changing climate.Understanding and managing negative health impacts of climate is a global challenge. The challenge is greater in regions with high poverty and weak institutions, however, and Africa is a continent where the health burden of climate is particularly acute. Observed climate variability in the modern era has been associated with widespread food insecurity, significant epidemics of infectious disease, and loss of life and livelihoods to climate extremes. Anthropogenic climate change is a further stress that has the potential to increase malnutrition, alter the distribution of diseases, and bring more frequent hydrological and temperature extremes to many regions across the continent.Skillful early warning systems and informed climate change adaptation strategies have the potential to enhance resilience to short-term climate variability and to buffer against negative impacts of climate change. But effective warnings and projections require both scientific and institutional capacity to address complex processes that are mediated by physical, ecological, and societal systems. Here the state of understanding climate impacts on health in Africa is summarized through a selective review that focuses on food security, infectious disease, and extreme events. The potential to apply scientific understanding to early warning and climate change projection is also considered.

Abstract:
Opera buffa is cited as the source for the topical variety of classical style instrumental music. It is also cited as a topic within instrumental music. This essay argues, with examples from works by Haydn, Mozart, Galuppi, Cimarosa, and Martín y Soler, that musical devices of opera buffa were not on the whole exported to instrumental music but rather were translated to the subtler and more refined instrumental idiom. When opera buffa is identified as a topic in instrumental music, it is more often the presumed gestural world of the comic stage that is evoked than the actual musical devices most characteristic of the genre. And when we study topics in opera—either buffa or seria—it is worth taking into account that they have the capacity not only redundantly to confirm verbal and visual cues, but also to complicate them by suggesting irony or parody, among other things.

Abstract:
The aim of the e-book is to present the theoretical, cognitive and practical aspects of the essence and complexity of operational management in a production company. The presented modern production methods together with the challenges and problems of contemporary enterprises should better help to understand the issues of sustainable development, with particular emphasis on waste. The book consists of six chapters devoted to relevant and topic issues relating to the core business of an industrial enterprise. Chapter 1 The nature of the industrial enterprise is an introduction to further considerations and deals with the essence of the basic aspects of the company. Both popular and less known definitions of an enterprise, its features, functions and principles of operation are presented. An important part of the chapter is the presentation and formulation of strategic, tactical and operational goals. Moreover, the division of enterprises is presented with the use of various criteria and the features of the industrial market, which make it distinct. Chapter 2 The operational management evolution and its role in the industrial enterprise discusses the evolution and concept of production and operational management. The management levels were also presented, indicating their most important functions. An integral part of the chapter is the essence of the production system, viewed through the prism of the five elements. Chapter 3 Functions and role in operations management presents the issues concerning the organization of production processes, production capacity and inventory management. This part also presents considerations on cooperation and collaboration between enterprises in the process of creating value. Chapter 4 Traditional methods used in operational activities focuses on methods such as benchmarking, outsourcing, core competences, JIT, MPR I and MRP II, as well as TQM and kaizen. Knowledge of these methods should contribute to understanding the activities of modern enterprises, the way of company functioning, the realization of production activities, as well as aspects related to building a competitive position. Chapter 5 Modern methods used in production-operations management discusses the less common and less frequently used production methods, based on a modern and innovative approach. In particular, it was focused on: Shop Floor Control and cooperative manufacturing, environment-conscious manufacturing (ECM) and life-cycle assessment ( LCA), waste management and recycling, Electronic Data Interchange (EDI), virtual enterprise, World Class Manufacturing (WCM), Quality Function Deployment (QFD) and House of Quality (HOQ), theory of constraints (TOC), Drum Buffer Rope (DBR), group technology (GT) and cellular manufacturing (CM), Demand Chain Management and competitive intelligence (CI). In the last section discusses: the role of sustainable statistical process control and Computer-Aided Process Planning in context formatting of information management. Chapter 6 Problems of sustainable development and challenges related to production and operations management describes the problem and challenges related to production and operations activities. In particular, attention was paid to the threats related to changes in global warming, the growing scale of waste, or the processes of globalization. It was pointed out that the emerging problem may be both a threat and a chance for the development of enterprises. An integral part of the chapter are also considerations on technical progress, innovation and the importance of human capital in operational activities.

Abstract:
It was found that with an increase in the content of crude fiber, dry matter and soluble sugars by 1%, the buffer capacity of alfalfa dry matter decreases by 0.04–0.10, 0.09–0.19 and 0.16–1.44 mol/l, respectively. An increase in the content of crude protein, crude ash and crude fat by 1 % increases the buffer capacity of dry matter by 0.07–0.40, 0.19–86 and 0.33–1.11 mol/l, respectively. Therefore, to create alfalfa varieties with a reduced buffer capacity without appreciable damage to the feed value, it is necessary to conduct breeding to increase the content of soluble sugars and, possibly, reduce the content of raw fat.

Abstract:
Abstract Buffers can improve the efficiency of manufacturing systems by accommodating the negative impacts of machine stoppage and maximize the system throughput. Buffers are often designed and integrated into manufacturing systems. This study investigates the effects of small internal buffers on the throughput of serial manufacturing systems using discrete-event simulation (DES). For a serial manufacturing system, its internal buffer can be designed as an idle station or a small conveyor. In the study, typical automotive assembly lines are used as serial manufacturing systems. In addition, the capacity of a small internal buffer and two small buffers are studied for optimal throughput. The study results provide a general approach on where to assign small internal buffers in serial manufacturing systems and what the effects of such buffers and their configurations are.

Evaluation of Electrochemical Treatment for Removal of Arsenic and Manganese from Field Soil. Illinois Center for Transportation, June 2021. http://dx.doi.org/10.36501/0197-9191/21-019.

Full text
Abstract:
Soils containing inorganic compounds are frequently encountered by transportation agencies during construction within the right-of-way, and they pose a threat to human health and the environment. As a result, construction activities may experience project delays and increased costs associated with management of inorganic compounds containing soils required to meet environmental regulations. Recalcitrance of metal-contaminated soils toward conventional treatment technologies is exacerbated in clay or organic content-rich fine-grained soils with low permeability and high sorption capacity because of increased treatment complexity, cost, and duration. The objective of this study was to develop an accelerated in situ electrochemical treatment approach to extract inorganic compounds from fine-grained soils, with the treatment time comparable to excavation and off-site disposal. Three reactor experiments were conducted on samples collected from two borehole locations from a field site in Illinois that contained arsenic (As)(~7.4 mg/kg) and manganese (Mn)(~700 mg/kg). A combination of hydrogen peroxide (H2O2) and/or citrate buffer solution was used to treat the soils. A low-intensity electrical field was applied to soil samples using a bench-scale reactor that resembles field-scale in situ electrochemical systems. For the treatment using 10% H2O2 and citrate buffer solution, average removal of 23% and 8% were achieved for Mn and As, respectively. With 4% H2O2 and citrate buffer, 39% and 24% removal were achieved for Mn and As; while using only citrate buffer as the electrolyte, 49% and 9% removal were achieved for Mn and As, respectively. All chemical regimes adopted in this study reduced the inorganic compound concentrations to below the maximum allowable concentration for Illinois as specified by the Illinois Environmental Protection Agency. The results from this work indicate that electrochemical systems that leverage low concentrations of hydrogen peroxide and citrate buffer can be effective for remediating soils containing manganese and arsenic.

Blumwald, Eduardo, and Avi Sadka. Citric acid metabolism and mobilization in citrus fruit. United States Department of Agriculture, October 2007. http://dx.doi.org/10.32747/2007.7587732.bard.

Full text
Abstract:
Accumulation of citric acid is a major determinant of maturity and fruit quality in citrus. Many citrus varieties accumulate citric acid in concentrations that exceed market desires, reducing grower income and consumer satisfaction. Citrate is accumulated in the vacuole of the juice sac cell, a process that requires both metabolic changes and transport across cellular membranes, in particular, the mitochondrial and the vacuolar (tonoplast) membranes. Although the accumulation of citrate in the vacuoles of juice cells has been clearly demonstrated, the mechanisms for vacuolar citrate homeostasis and the components controlling citrate metabolism and transport are still unknown. Previous results in the PIs’ laboratories have indicated that the expression of a large number of a large number of proteins is enhanced during fruit development, and that the regulation of sugar and acid content in fruits is correlated with the differential expression of a large number of proteins that could play significant roles in fruit acid accumulation and/or regulation of acid content. The objectives of this proposal are: i) the characterization of transporters that mediate the transport of citrate and determine their role in uptake/retrieval in juice sac cells; ii) the study of citric acid metabolism, in particular the effect of arsenical compounds affecting citric acid levels and mobilization; and iii) the development of a citrus fruit proteomics platform to identify and characterize key processes associated with fruit development in general and sugar and acid accumulation in particular. The understanding of the cellular processes that determine the citrate content in citrus fruits will contribute to the development of tools aimed at the enhancement of citrus fruit quality. Our efforts resulted in the identification, cloning and characterization of CsCit1 (Citrus sinensis citrate transporter 1) from Navel oranges (Citrus sinesins cv Washington). Higher levels of CsCit1 transcripts were detected at later stages of fruit development that coincided with the decrease in the juice cell citrate concentrations (Shimada et al., 2006). Our functional analysis revealed that CsCit1 mediates the vacuolar efflux of citrate and that the CsCit1 operates as an electroneutral 1CitrateH2-/2H+ symporter. Our results supported the notion that it is the low permeable citrateH2 - the anion that establishes the buffer capacity of the fruit and determines its overall acidity. On the other hand, it is the more permeable form, CitrateH2-, which is being exported into the cytosol during maturation and controls the citrate catabolism in the juice cells. Our Mass-Spectrometry-based proteomics efforts (using MALDI-TOF-TOF and LC2- MS-MS) identified a large number of fruit juice sac cell proteins and established comparisons of protein synthesis patterns during fruit development. So far, we have identified over 1,500 fruit specific proteins that play roles in sugar metabolism, citric acid cycle, signaling, transport, processing, etc., and organized these proteins into 84 known biosynthetic pathways (Katz et al. 2007). This data is now being integrated in a public database and will serve as a valuable tool for the scientific community in general and fruit scientists in particular. Using molecular, biochemical and physiological approaches we have identified factors affecting the activity of aconitase, which catalyze the first step of citrate catabolism (Shlizerman et al., 2007). Iron limitation specifically reduced the activity of the cytosolic, but not the mitochondrial, aconitase, increasing the acid level in the fruit. Citramalate (a natural compound in the juice) also inhibits the activity of aconitase, and it plays a major role in acid accumulation during the first half of fruit development. On the other hand, arsenite induced increased levels of aconitase, decreasing fruit acidity. We have initiated studies aimed at the identification of the citramalate biosynthetic pathway and the role(s) of isopropylmalate synthase in this pathway. These studies, especially those involved aconitase inhibition by citramalate, are aimed at the development of tools to control fruit acidity, particularly in those cases where acid level declines below the desired threshold. Our work has significant implications both scientifically and practically and is directly aimed at the improvement of fruit quality through the improvement of existing pre- and post-harvest fruit treatments.
