Description

Diverse oleaginous yeasts can grow and accumulate lipid on a broad range of competitive substrates. In this study crude glycerol from conventional biodiesel production was used as substrate for lipid production via the oleaginous yeasts. Various cultivation conditions were tested – different C/N ratios, temperatures and addition of salts. Candida lipolytica, Yarrowia lipolytica, Trichochsporon fermentans produced up to maximum of 22 % lipid (w/w) relating to the biomass at specific cultivation conditions. Scale up experiments revealed the further challenges of the lipid production via oleaginous yeasts - adhesion of the yeast, production of citric acid, low biomass and lipid yield. The lipid yield was 17 % (w/w) relating to the biomass despite addition of detergent.
