PROCESS FOR THE PRODUCTION OF LIPIDS FROM BIOMASS

摘要

Process for the production of lipids from biomass including at least one polysaccharide, which comprises fermentation of a biomass hydrolysate using an oleaginous microorganism and separation of oleaginous cellular biomass comprising lipids. An aqueous fraction obtained by reverse osmosis of a spent fermentation broth is recycled as a feed for growth of the oleaginous microorganism. The lipids thus obtained can be advantageously used in the production of biodiesel or green diesel which can be used as such, or in a mixture with other automotive fuels.
