Claim Text:
1. A process for the production of lipids from biomass including at least one polysaccharide comprising: subjecting said biomass, including at least one polysaccharide to acid hydrolysis obtaining a first mixture comprising a first solid phase and a first aqueous phase; feeding said first aqueous phase to a fermentation device in the presence of at least one oleaginous yeast obtaining a first fermentation broth comprising a first oleaginous cellular biomass; subjecting said first solid phase to acid hydrolysis or to enzymatic hydrolysis obtaining a second mixture comprising a second solid phase and a second aqueous phase; feeding said second aqueous phase to said fermentation device in the presence of said first fermentation broth obtaining a second fermentation broth comprising a second oleaginous cellular biomass including lipids; subjecting at least a part of said second fermentation broth to microfiltration obtaining a retentate and a permeate; and feeding said retentate to said fermentation device.
