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.
Under low nitrogen growth conditions it accumulates lipids and carotenoids. It is currently being explored as an alternative host for the production of advanced biofuels and chemicals.  In addition, it can serve as a new model system for understanding the genetic control of lipid productivity and for comparative studies with other oleaginous yeast, such as Yarrowia and Lipomyces spp.   The strains IFO0880, IFO0559, IFO1236 were obtained from NBRC culture collection (http://www.nbrc.nite.go.jp).  For further information, please email: skerker@berkeley.edu and aparkin@lbl.gov.
