Abstract: The present invention relates to a variant of oleaginous yeast of the species Trichosporon oleaginosus characterized by mutations affecting cell wall synthesis that change the morphology thereof with respect to the wild-type strain of the same species. In particular, thanks to said mutations, cell aggregates are formed which, with respect to the wild-type strain of the same species, lower the viscosity of the culture broth, are more easily separable therefrom and thus make their recovery easier. Said variant of oleaginous yeast of the species Trichosporon oleaginosus is also characterized by yields of oleaginous cellular biomass and intracellular accumulation of lipids that are similar or even higher than those of the wild-type strain. Further, the present invention relates to a process for the production of lipids through said variant of oleaginous yeast of the species Trichosporon oleaginosus.

Abstract: Process for the production of lipids from biomass including at least one polysaccharide comprising: —subjecting said biomass to hydrolysis to obtain a mixture comprising a first solid phase and a first aqueous phase; —preparing an inoculum comprising at least one oleaginous microorganism in a first fermentation device to obtain a first fermentation broth; —feeding said first aqueous phase and said first fermentation broth to a second fermentation device to obtain a second fermentation broth; —subjecting at least a portion of said second fermentation broth to microfiltration to obtain a first retentate and a first permeate; —feeding said first retentate to said second fermentation device; —subjecting said first permeate to a purification treatment to obtain a second permeate and a second retentate; —feeding said second retentate to said second fermentation device; —at the end of said fermentation, subjecting said second fermentation broth to separation to obtain an aqueous suspension of oleaginous cellular bio
