sp. nov., a thermotolerant yeast species isolated from a stream from a hot-spring area in Japan Free

Abstract

Anamorphic basidiomycetous yeast strains M9962 and M9963 were isolated from water samples collected from a small stream in Ohwakudani, Hakone, a hot-spring area in Japan. These belonged to a single species and were phylogenetically closely related to , although the ability to form ballistoconidia was not observed. Based on sequence analyses of the D1/D2 domain of the LSU rDNA and ITS regions and differences in G+C content, the name sp. nov. Takashima, Sugita, Toriumi et Nakase (Trichosporonales, Tremellomycetes, Basiomycota) is proposed for these isolates, with strain M9962 (=SP-5 =JCM 11965 =CBS 9427) as the type strain. The strains grew in YM broth at 47 °C and in YM broth with the pH adjusted to 1.5 by HCl, indicating that the species is thermotolerant and acid-tolerant.
