Abstract

Three yeast strains, DMKU-GTSP8-6, DMKU-GTSP8-14T and DMKU-JED8-73, were isolated from food waste in Thailand. Based on the phenotypic characteristics and sequence analysis of the D1/D2 domain of the large subunit (LSU) rRNA gene and the internal transcribed spacer (ITS) region, it was revealed that the three strains clustered with the Magnusiomyces/Saprochaete clade. These strains were distinguished from the closely related species Saprochaete quercus CBS 750.85, Magnusiomyces ovetensis CBS 192.55T, Magnusiomyces starmeri CBS 780.96T, Saprochaete chiloensis CBS 8187T and Magnusiomyces ingens CBS 517.90T by 11.4, 13.1, 11.9, 11.2 and 12.6 % sequence divergence in the D1/D2 domain and by 34.6, 34.5, 33.6, 33.2 and 34.9 % sequence divergence in the ITS region, respectively. The new species, which does not produce ascospores, is described as Magnusiomyces siamensis. The holotype of Magnusiomyces siamensis is TBRC 15056T, and the isotypes are DMKU-GTSP8-14T and PYCC 9023T.
