Lipid production by yeasts growing on biodiesel-derived crude glycerol: strain selection and impact of substrate concentration on the fermentation efficiency

Abstract

Very scarce numbers of reports have indicated the production of SCO by L. starkeyi and R. toruloides growing on glycerol. We report here that these yeasts are able efficiently to convert raw glycerol into SCO, while L. starkeyi also synthesizes intracellular polysaccharides in marked quantities.
