Rhodosporidium toruloides is a nonpathogenic, red-colored basidiomycetous fungus. It is an oleaginous yeast that can accumulate lipids over 70% of its dry cell weight.1 It is also a good producer for carotenoids and some important enzymes. R. toruloides has a broad substrate scope and excellent tolerance to inhibitory compounds found in biomass hydrolysates.2
R. toruloides NP11 is a haploid strain3 that is isolated from the parent diploid strain R. toruloides CGMCC 2.1389 (equals to R. toruloides CBS 6016).
