The present invention concerns an oleaginous yeast variant of the speciescharacterized by higher biomass yields and intra-cellular lipid accumulation useful for the production of bio-fuels higher, in determined conditions, with respect to the wild type strain of the same species. Furthermore, the invention concerns a method through which said oleaginous yeast variant of the specieswas obtained. The invention further concerns the lipid production by means of said variant strain of oleaginous yeast of the species

Oleaginous yeast variant, method for obtaining thereof and use thereof for lipid production

Process for the production of lipids from biomass comprising polysaccharides. The biomass is subjected to acid hydrolysis to obtain a solid phase and an aqueous phase. The solid phase is subjected to acid or to enzymatic hydrolysis obtaining a further solid phase and a further aqueous phase. The aqueous phases obtained from both hydrolysis steps are subjected to fermentation with an oleaginous yeast. The obtained fermentation broth comprises oleaginous cellular biomass which is subjected to microfiltration for the isolation of lipids. Said lipids can be used in the production of biodiesel or green diesel.
