The article presents the results of studies dependence cows’ milk productivity on level lipid peroxidation and antioxidant defense in their body. For experiment two groups lactating cows were formed, 10 animals each: group 1 – livestock with a high concentration products blood low antioxidants; 2 values these indicators within reference interval. research indicate that average daily yield was l...

BACKGROUND Microbial lipid production using renewable feedstock shows great promise for the biodiesel industry. RESULTS In this study, the ability of a lipid-engineered Yarrowia lipolytica strain JMY4086 to produce lipids using molasses and crude glycerol under different oxygenation conditions and at different inoculum densities was evaluated in fed-batch cultures. The greatest lipid content,...

Microalgae are a promising feedstock for biofuel production. Microalgal metabolic pathways are heavily influenced by environmental factors. For instance, lipid metabolism can be induced by nitrogen-limiting conditions. However, the underlying mechanisms of lipid biosynthesis are unclear. In this study, we analyzed the global metabolic profiles of three genetically closely related Chlorella stra...

Lipid productivity is a critical variable for evaluating algal species for biodiesel production. The pennate diatom Nitzschia closterium (W. Sm.) isolated from the local water body of Madurai was cultivated in four different media (WCg, Csi, F/2 and Diatom medium) and screened for the presence of neutral lipid content using Nile red fluorescent dye. The relative abundance of lipid content was e...

BACKGROUND Rising CO2 concentration was reported to increase phytoplankton growth rate as well as lipid productivity. This has raised questions regarding the NADPH supply for high lipid synthesis as well as rapid growth of algal cells. RESULTS In this study, growth, lipid content, photosynthetic performance, the activity, and expression of key enzymes in Calvin cycle and oxidative pentose pho...

The transition of planktonic late-stage barnacle larvae to a benthic life requires enough energy power settlement and metamorphosis, may be compromised by food limitation during early ontogeny. We carried out comparative study better understand the larval physiology space-monopolizing barnacles exposed contrasting regimes primary productivity: Chthamalus bisinuatus under meso-oligotrophic regim...

Heterosigma akashiwo is an excellent candidate for growth on industrial emissions since this alga has the ability to metabolize gaseous nitric oxide (NO) into cellular nitrogen via a novel chimeric protein (NR2-2/2HbN) and also tolerates wide fluctuations in temperature, salinity, and nutrient conditions. Here, we evaluated biomass productivity and composition, photosynthetic efficiency, and ex...

Numerous recent studies have identified microalgae biofuel as one of the major renewable energy sources for sustainable development due to their high biomass productivity, lipid content, and availability locally adapted strains in various geographical locations. There been minimal on fatty acid composition production local species Sabah, Malaysia. Thus, screening capable producing biodiesel can...

The problem of assessing the impact of firm entry and exit on aggregate productivity growth is addressed. The proposed method overcomes some problems with currently proposed methods. The paper also addresses some of the problems involved in aggregating outputs and inputs when firms enter and exit so that the one output and one input aggregate productivity decompositions can be applied. It turns...

PH (Puissance de Hydrogen) is an essential ingredient of soil that effects on fertility and productivity of dirt. Barddhaman district is a part of Lower Gangetic Plain fully covered by alluvial soil and popularly known as 'rice bowl of West Bengal' owing to its lofty production. This data article provides a block level data on soil PH that is essential for further investigation of the relations...
