Photosynthesis is fundamental to biomass production, but is a dynamic process sensitive to environmental constraints. In recent years, approaches to increase biomass and grain yield by altering photosynthetically related processes in the plant have received considerable attention. However, improving biomass yield requires a predictive understanding of the molecular mechanisms that allow photosynthesis to be adjusted. The important roles of metabolic reactions external to those directly involved in photosynthesis are highlighted in this review; however, our major focus is on the routes taken to

The rates of light limited (αB) and light saturated (PmaxB) photosynthesis per unit chlorophyll often showed significant differences between samples collected from the top and the bottom of the mixed layer in Lake Erken (59° 51′ N). The importance of these vertical variations to the photosynthetic rate of the lake as a whole was examined by systematically changing the vertical weighting given to the biomass specific photosynthetic rates associated with each depth, when calculating integral photosynthesis. These simulations, carried out over the 3 month period from July to September of 1987, su

Maize (Zea mays L.) benefits from heterosis in-yield formation and photosynthetic efficiency through optimizing canopy structure and improving leaf photosynthesis. However, the role of canopy structure and photosynthetic capacity in determining heterosis in biomass production and radiation use efficiency has not been separately clarified. We developed a quantitative framework based on a phytomer-based three-dimensional canopy photosynthesis model and simulated light capture and canopy photosynthetic production in scenarios with and without heterosis in either canopy structure or leaf photosynt

Major research on photosynthesis has been carried out under steady light. However, in the natural environment, steady light is rare, and light intensity is always changing. Changing light affects (usually reduces) photosynthetic carbon assimilation and causes decreases in biomass and yield. Ecologists first observed the importance of changing light for plant growth in the understory; other researchers noticed that changing light in the crop canopy also seriously affects yield.

In the continental United States, mean surface air temperature is expected to increase by up to 5°C within 100 years. With hotter temperatures, leaf budbreak is expected to occur earlier in forests, and leaf area is expected to increase in locations where temperature is limiting. The response of plant photosynthesis to hotter temperatures is less certain; plant productivity could increase or decrease. Past studies have found intraspecific variation in the responses of forest tree productivity, phenology, canopy leaf area, and leaf isoprene emission to warming, which all influence carbon uptake

CO2 storage in the oceans is strongly affected by biological processes. Production of organic matter through phytoplankton photosynthesis drives CO2 sequestration, which feeds back to atmospheric CO2 and global climate. The ongoing increase in atmospheric CO2 and temperature is strongly associated with changes in ocean chemistry and increasing seawater temperatures. To investigate these impacts on coastal phytoplankton under conditions predicted for the year 2100 (pCO2 elevated to 800 μatm and +4 °C temperature), three factorial experiments were conducted with natural communities sampled from

Net primary productivity (NPP) is the amount of C or biomass that accumulates over time and is photosynthesis—autotroph respiration. Annual NPP is estimated by summing positive biomass increments across time periods during the growing season, including offtake to herbivores, which can be high in grasslands.

Abstract. Thin-layer drying studies have been done for various materials, including vegetables, fruit, grains, wood, plants, biomass, and others. The present study is concerned with the investigation of the drying kinetics of harvested photosynthetic non-sulfur bacteria (PNSB) biomass. Four different drying models, i.e., Logarithmic, Newton, Page, and Henderson and Pabis were fitted to the experimental data obtained from drying a thin-layer of biomass in a laboratory oven at 60, 80, 100, and 120 ℃. The results were assessed on statistical parameters such as the Akaike information criterion, an

Erbium belongs to rare earth elements critical for industry, especially nuclear technology. Cyanobacteria Arthospira platensis was used for Er(III) removal from wastewater by applying biosorption and bioaccumulation processes. The influence of pH, Er(III) concentration, contact time and temperature on the biosorption capacity of Arthospira platensis was determined. The optimal conditions for Er(III) removal were defined as pH 3.0, time 15 min and temperature 20 ◦C, when 30 mg/g of Er(III) were removed. The kinetics of the process was better described by the pseudo-first-order model, while equi

A photobioreactor with an optical system that spatially dilutes solar photosynthetic active radiation has been designed, built, and tested at the Utah State University Biofuels Center. This photobioreactor could be used to produce microalgal biomass for a number of purposes, such as feedstock for an energy conversion process or high-value products such as pharmaceuticals and nutraceuticals. In addition, the reactor could be used to perform services such as removing nitrates, phosphates, and other contaminants from waste water, as well as scrubbing toxic gases and carbon dioxide from flue gas.

Abstract Stringent emission norms worldwide have provided an impetus to explore alternative sustainable fuels that are carbon neutral. Hydrogen is touted as one of the potential fuels that aid decarbonization. Biomass, especially the ones that do not compete with the food needs are considered promising feedstock for hydrogen production by thermal conversion. In the current study, the performance of the macroalga Macrocystis pyrifera in the thermal conversion through pyrolysis as a potential biomass for hydrogen production was examined. The macroalga Macrocystis pyrifera is a giant brown seawee

This paper describes a unique analytical model created to assess the maximum potential for algae production in Texas. The model, which merges engineering, biology and geosciences into a singular analysis, aims to identify suitable growth locations and estimate the quantity of algae-based oils that can be potentially produced in Texas. The model incorporates geographically- and temporally-resolved data on sunlight, anthropogenic CO2 emissions, and saline or brackish water availability. These data are then overlaid with first-order biological approximations for algae growth calculations in order

Hydrogen has been shown to be an essential potential energy carrier with some significant opportunities to reduce carbon emissions related to power generation and provide an alternative for power generation for several applications. Hydrogen is abundant as an element in our Earth and is widely used in the form of water and other substances as a composite[BAM1] (Turner 2004, Dawood, Anda and Shafiullah 2020). There can be various uses for hydrogen, such as fuel cells and a by-product for water. This enables it to be clean fuel in terms of carbon emissions. Hydrogen can be obtained from many res

US Environmental Protection Agency (USEPA) approved algaecides and herbicides are frequently utilized to manage nuisance algae and aquatic macrophytes. However, there is limited information available on the effectiveness of these products for the management of starry stonewort. Thus, the goal of this research was to discern effective chemical control products for later growth stages of starry stonewort using mesocosm studies. Eleven treatments were evaluated using various combinations of four copper-based products, endothall, diquat, and carfentrazone – all with USEPA registrations for use in

The synthesis of carotenoids has been studied toward enhancing the production of ketocarotenoids, since fish and crustaceans raised by aquaculture require astaxanthin and other ketocaroteinoids in their feed for desirable pigmentation. Notable progress has been made in attaining the goals of determining improved conditions for ketocarotenoid production in Haematococcus pluvialis and in elucidating the carotenoid biosynthetic pathway. For production of astaxanthin a number of strains of the green alga Haematococcus were evaluated, a strain CCAG was found to be optimal for photoautotrophic growt

The function of the 30-kilodalton movement protein (MP) of tobacco mosaic virus (TMV) is to facilitate cell-to-cell movement of viral progeny in infected plants. Our earlier findings have indicated that this protein has a direct effect on plasmodesmal function. In addition, these studies demonstrated that constitutive expression of the TMV MP gene (under the control of the CaMV 35S promoter) in transgenic tobacco plants significantly affects carbon metabolism in source leaves and alters the biomass distribution between the various plant organs.
