Five strains of the novel ascogenous yeast species Lipomyces orientalis sp. nov. were isolated from soil samples collected in Vietnam. The yeast forms asci containing one to four ascospores. The ascospores of L. orientalis have warty surfaces and differ from the characteristic striated ascospores of Lipomyces tetrasporus. Phylogenetic analyses of D1/D2 26S rDNA and ITS sequences indicate that L. orientalis and L. tetrasporus are closely related, but they differ from each other by 6 nucleotides in the D1/D2 region and 16 nucleotides in the ITS region. The type culture is strain Lip 95T (=CBS 10300T=NRRL Y-27927T).
A protocol for the preparation of malt broth, a map showing the locations of the sampling sites, an electron micrograph of ascospores of strain Lip 95T and a neighbour-joining tree based on D1/D2 sequences are available as supplementary material in IJSEM Online.
