11-18: Lipid fermentation using yeast Cryptococcus curvatus and hydrolyzed ammonia pretreated switchgrass

Yeast Cryptococcus curvatus (ATCC 20508) was cultivated on centrifuged-hydrolyzed and ammonia-pretreated switchgrass.  Different sugars utilized including glucose, xylose, arabinose and cellobiose and lipid formation were monitored over a period of 120 h. All sugars were completely consumed by the end of 120 h. The maximum biomass cell number per volume was approximately 1.76E+10 cell per ml corresponding to lipid formation of 0.38 g per g dry cell.
