NOVELTY - A Rhodosporidium toruloides CECT 13085 strain or its mutant which maintains the ability to accumulate lipid to at least 50% dry weight, the ability to grow in the presence of no detoxifying biomass hydrolysates and ability to metabolize xylose, is new.    USE - The Rhodosporidium toruloides CECT 13085 strain or its mutant and methods are useful for obtaining triglyceride-rich microbial biomass, composition enriched in lipids, paraffins, biodiesel, biolubricants, and biosurfactants (all claimed).    ADVANTAGE - The Rhodosporidium toruloides CECT 13085 strain or its mutant has the ability to efficiently metabolize different carbon sources including, without limitation, glucose, xylose, crude glycerin or sugars present in lignocellulosic biomass hydrolysates without detoxifying, and also has the ability to accumulate lipid to at least 50% dry weight.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are:    (1) a method for obtaining triglyceride-rich microbial biomass comprising: (i) culturing the microorganism in a culture medium comprising at least one carbon source and at least one nitrogen source, under conditions suitable for the microorganism growth conditions; and (ii) separating the microbial biomass of the culture medium;    (2) triglyceride-rich microbial biomass obtainable from the method;    (3) a method for obtaining a composition enriched in lipids comprising: (i) obtaining the microbial biomass; and (ii) extracting lipids of the microbial biomass;    (4) a method for obtaining paraffins comprising: (i) obtaining a composition enriched in lipids from the microbial biomass; (ii) refining the lipids obtained in step (ii); and (iii) converting the refined mixture of lipids obtained in step (ii) into paraffins;    (5) a method for obtaining biodiesel comprising: (i) obtaining a composition enriched in lipids from microbial biomass; (ii) refining the lipids; and (iii) converting the refined mixture of lipids obtained in step (ii) into biodiesel;    (6) a method for obtaining biolubricants comprising: (i) obtaining a composition enriched in lipids from microbial biomass; (ii) refining the lipids; and (iii) converting the refined mixture of lipids obtained in step (ii) into biolubricants; and    (7) a method for obtaining biosurfactants comprising: (i) obtaining a composition enriched in lipids from microbial biomass; (ii) refining the lipids; and (iii) converting the refined mixture of lipids obtained in step (ii) into biolubricants.
