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.

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.
