New direct evidence of the relationship between the yeast form genus Rhodotorula and heterobasidiomycetous fungi is presented, namely, a new species of the heterobasidiomycetous genus Rhodosporidium with a rhodotoruloid yeast phase. The new species has the Rhodosporidium life cycle but differs significantly from, and is not interfertile with, described species of the genus. It was isolated from...

Carotenoids are valuable pigments of commercial interest for various health benefits. There is rising demand for natural carotenoids from microorganisms, although the majority of industrially produced carotenoids are currently chemically synthesized. Rhodosporidium toruloides is oleaginous red yeast, which can produce large amounts of carotenoids and lipids simultaneously. It is also able to as...

The phenotypic and genetic heterogeneity of the basidiomycetous yeast species Rhodosporidium kratochvilovae was investigated in a group of recent isolates and collection strains. A polyphasic taxonomic approach was followed which included micromorphological studies, nuclear staining, determination of sexual compatibility, physiological characterization, comparison of electrophoretic isoenzyme p...

Phylogenetic relationships among heterobasidiomycetous yeasts, including anamorphic and teleomorphic taxa, have been compared from the sequence similarity of small (18S) and large (25S) subunit ribosomal RNA. Species examined were Cystofilobasidium capitatum, Filobasidiella neoformans, Fi/obasidium floriforme, Leucosporidium scottii, Malassezia furfur, M. pachydermatis, Phaffia rhodozyma, Rhodo...

We report the sequencing of the basidiomycetous yeast Rhodosporidium toruloides CECT1137. The current assembly comprises 62 scaffolds, for a total size of ca. 20.45 Mbp and a G+C content of ca. 61.9%. The genome annotation predicts 8,206 putative protein-coding genes.

We report the de novo assembled 20.05-Mb draft genome of the red yeast Rhodosporidium toruloides MTCC 457, predicted to encode 5,993 proteins, 4 rRNAs, and 125 tRNAs. Proteins known to be unique to oleaginous fungi are present among the predicted proteins. The genome sequence will be valuable for molecular genetic analysis and manipulation of lipid accumulation in this yeast and for developing ...

Single cell oils (SCOs) are considered potential raw material for the production of biodiesel. Rhodosporidium sp. and Lipomyces sp. are good candidates for SCO production. Lipid extractability differs according to yeast species and literature on the most suitable method for each oleaginous yeast species is scarce. This work aimed to investigate the efficiency of the most cited strategies for ex...
