Lipid Bodies and Lipid Accumulation in Oleaginous Plants and Microorganisms

The biochemistry and molecular biology of lipid accumulation in oleaginous microorganisms.

Regulation of lipid accumulation in oleaginous micro-organisms.

A small number of eukaryotic micro-organisms, the oleaginous species, can accumulate triacylglycerols as cellular storage lipids, sometimes up to 70% of the biomass. Some of these lipids, particularly those containing high proportions of polyunsaturated fatty acids of nutritional and dietary importance, are now in commercial production; these are known as single-cell oils. The biochemistry of l...

A biochemical explanation for lipid accumulation in Candida 107 and other oleaginous micro-organisms.

The biochemical explanation for lipid accumulation was investigated principally in Candida 107 and, for comparison, in the non-oleaginous yeast Candida utilis. There were no significant differences between these two yeasts in their control of glucose uptake; in both yeasts, the rates of glucose uptake were independent of the growth rate and were higher in carbon-limited chemostat cultures than ...

Effects of Alcohol Compounds on the Growth and Lipid Accumulation of Oleaginous Yeast Trichosporon fermentans

The inhibitors present in dilute acid-treated lignocellulosic hydrolysates would show great effect on the growth and product formation of microorganisms. To understand their inhibitory law and mechanism on oleaginous microorganism could help improving the efficiency of lignocellulose hydrolysis, detoxification, and lipid fermentation. The effects of four representative alcohol compounds present...

Effect of organic acids on the growth and lipid accumulation of oleaginous yeast Trichosporon fermentans

BACKGROUND Microbial lipids have drawn increasing attention in recent years as promising raw materials for biodiesel production, and the use of lignocellulosic hydrolysates as carbon sources seems to be a feasible strategy for cost-effective lipid fermentation with oleaginous microorganisms on a large scale. During the hydrolysis of lignocellulosic materials with dilute acid, however, various k...
