Abstract:

Heavy metal (HM) pollution has become one of the most important environmental problems of the present day, as a result of the developing industrial activities. Accordingly, it is important to understand microorganism activities in soil ecosystems that have been exposed to HMs for a long time. The aim of this study was to show the potential effects of ores on soil carbon and nitrogen mineralizations which were taken from copper (Cu) and lead (Pb) mines in Balıkesir-Balya and Kastamonu-Küre districts in Turkey. The carbon (C) and nitrogen (N) mineralizations were determined by using the CO2 resp

Abstract:

Bacteria-based mineralization is a new technique to use the steel slag. In this article, an experimental examination was performed to find out the steel slag advancement by the addition of the microbial agent that has the possibility to accelerate mineralization ability of bacteria. It is observed that, under natural and CO2 pressure curing conditions, the carbonation rate is significantly raised when microorganisms are added to the steel slag. The increased ratio of microorganisms leads to a better carbonation rate. The reaction products formed by bacteria mineralization were analyzed with th

Abstract:

Mineralization of the cartilage matrix in embryonic long bones and growth plates is preceded by hypertrophy of chondrocytes. We hypothesize that the swollen hypertrophic cells exert pressure on the matrix, and that this pressure plays a role in the cartilage mineralization process. For this study, we asked the following questions. First, does the ratio of cell volume to matrix volume (CV/MV) increase from the proliferation to the hypertrophic zone in embryonic long bones? Second, is there a correlation between cell-volume increase and the mineralization rate in embryonic and postnatal long bon

An investigation of in situ N mineralization, using undisturbed soil samples, indicated a negative relationship between the mineral N content [(NO3+NH4)-N] at the beginning of the experiment and the mineral N produced during it.

This value would be related to the size of the mineralizable N pool. If this hypothesis is true, the amount of mineralizable N could be estimated from in situ incubations and utilized in the mod

Abstract. The depolymerization of soil organic matter, such as proteins and (oligo-)peptides, into monomers (e.g. amino acids) is currently considered to be the rate-limiting step for nitrogen (N) availability in terrestrial ecosystems. The mineralization of free amino acids (FAAs), liberated by the depolymerization of peptides, is an important fraction of the total mineralization of organic N. Hence, the accurate assessment of peptide depolymerization and FAA mineralization rates is important in order to gain a better process-based understanding of the soil N cycle.

Abstract:

To estimate the amount of nitrate lost due to leaching during the growth period of potatoes and the amount of mineral nitrogen present in the soil at harvest time, i.e. residual mineral nitrogen, calculations were performed with a previously derived simulation model for the response of potatoes to nitrogen. In the calculations those factors were varied that were considered to affect the amount of nitrate lost due to leaching: precipitation in spring and summer, soil type, mineralization rate of soil organic matter, and amount of fertilizer nitrogen applied. It was calculated that the total los

Abstract:

In order to discuss the problems of the transformation of soil nitrogen and nitrogen leaching in saline farmland, this study carried out a split-plot experiment with returning straw and various nitrogen application rates. The main treatment of the experiment was returning corn straw, at quantities of 0.64 g (C1) and 0 g (C0), and the secondary treatment was nitrogen fertilizer (urea) at the quantities of 0 g (N0), 0.015 g (N1) and 0.03 g (N2). The results showed that, firstly, with the extension of the incubation time, the nitrogen nitrification rate of saline soil in each treatment decreased

Abstract:

Mineralized soil N from meadow soils will become an important source of N to following crops in low-input biological cropping systems. The C and N mineralization rates of soils from 34 sites situated on dairy farms recently converted to biological cropping systems were evaluated in a 56-wk incubation at 25° C. Data on C and N mineralization were fitted to first-order kinetic models. Carbon and N generally presented similar patterns of mineralization. Total mineralized N (Nm) ranged between 88 and 235 mg N kg-1 soil, which represented 6.6 to 22% of total N. Carbon mineralization (Cm) rate was b

Abstract:

The present work deals with establishing the pathway for the selection of additives for intensification of the sonolytic degradation of chlorobenzene. The degradation of chlorobenzene has been investigated in the presence of different additives such as CuO, TiO2, nano-TiO2 and NaCl. The reaction has been monitored in terms of the concentration of the parent pollutant as well as the extent of mineralization. The first-order kinetic rate constant for the removal of chlorobenzene has been evaluated for different loadings of additives. It has been observed that the extent of degradation and minera

Soil organic carbon (SOC) mineralization (conversion of carbonaceous material to carbon dioxide) plays a central role in global carbon cycle. However, the effects of SOC mineralization under different saline–alkali stress conditions are poorly understood. In order to understand the carbon mineralization processes, four paddy fields with different saline and alkali degrees were chosen as the experimental samples and the soil CO2 emission fluxes at nine different time steps of the whole simulation experiment were observed.

Abstract:

Traditional N mineralization studies have been conducted by soil scientists using soils and temperatures found in field production. As temperature, in part, governs the rate of mineralization, and container substrates reach much higher temperatures than do soils, the effect of these elevated temperatures on mineralization must be considered to begin to understand N mineralization in container substrates during production. The N mineralization patterns of three composts [turkey (Meleagris gallopavo) litter, yard waste, and municipal waste] were determined under three temperature regimes (45, 25

The organic carbon mineralization process reflects the release intensity of soil CO2. Therefore, the study of organic carbon mineralization and particle composition analysis of soft rock and sand compound soil can provide technical support and a theoretical basis for soil organic reconstruction (soil structure, materials and biological nutrition). Based on previous research, four treatments were selected: CK (soft rock:sand=0:1), C1 (soft rock:sand=1:5), C2 (soft rock:sand=1:2) and C3 (soft rock:sand=1:1), respectively.

The pathways by which salinity indirectly affects soil carbon mineralization rates need to be investigated. Whether or not the response mode is consistent among different land-use types, as well as the intrinsic links and interactions between soil microbial resource limitation, environmental stress, microbial extracellular enzyme activity, and soil carbon mineralization, remain to be demo

ABSTRACT The complex pathogenesis of mineralization defects seen in inherited and/or acquired hypophosphatemic disorders suggests that local inorganic phosphate (Pi) regulation by osteoblasts may be a rate-limiting step in physiological bone mineralization. To test whether an osteoblast autonomous phosphate regulatory system regulates mineralization, we manipulated well-established in vivo and in vitro models to study mineralization stages separately from cellular proliferation/differentiation stages of osteogenesis.

A novel solid phase aerobic digestion process for high strength organic wastewaters using adsorbent polymer gel particles was developed. Characteristics of organic removal and water evaporation were investigated using laboratory scale experimental apparatus. It was found that the removal rate of organic pollutants adsorbed on polymer gels increased with the increase in organic concentration of wastewater and the temperature. The maximum rate of organic removal was as high as 10 kg-TOC.m−3.d−1 at about 50°C, but the elevated temperature beyond 50°C hindered the rate of organic removal and thus
