Cryptococcus tepidarius sp. nov., a thermotolerant yeast species isolated from a stream from a hot-spring area in Japan Takashima, Masako and Sugita, Takashi and Toriumi, Yoshimi and Nakase, Takashi,, 59, 181-185 (2009), doi = https://doi.org/10.1099/ijs.0.004515-0, publicationName = Microbiology Society, issn = 1466-5026, abstract= Anamorphic basidiomycetous yeast strains M9962T 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 Bullera lagerstroemiae, 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 Cryptococcus tepidarius sp. nov. Takashima, Sugita, Toriumi et Nakase (Trichosporonales, Tremellomycetes, Basiomycota) is proposed for these isolates, with strain M9962T (=SP-5T =JCM 11965T =CBS 9427T) 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., language=, type=
