“…Based on these results, we concluded that our isolates represent a distinct species. The higher growth temperature of this species also supported this separation (Van Uden, 1984). The physiological and biochemical properties of this species were similar to those of B. formosensis, B. koratensis and B. lagerstroemiae, but the latter species differ by their ability to assimilate sodium nitrite and their inability to grow at 37 u C ( Table 1).…”

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 M9962 T (5SP-5 T 5JCM 11965 T 5CBS 9427 T ) as the type strain. The strains grew in YM broth at 47 6C and in YM broth with the pH adjusted to 1.5 by HCl, indicating that the species is thermotolerant and acid-tolerant.

Abstract:The yeast strain (Y18) was isolated from a soil sample collected from Fildes Peninsula, Antarctica. The strain is a psychrophilic yeast with optimum and maximum growth temperatures of 10 °C and 18 °C, respectively. Teliospores were formed after 7 d on malt agar, when the germination of teliospores was observed. Both inositol and D-glucuronate were assimilated. Positive results of the DBB (diazonium blue B) color reaction, urease test, and starch formation were observed. The major CoQ is Q 8 . All results indicated that Y18 belongs to the genes of Mrakia. The 18S rDNA sequence analyses showed that Y18 is closely related to Mrakia frigida. DNA-DNA relatedness study, and some biochemistry characteristics indicated that Y18 represents a new species for which Mrakia psychrophila sp. nov. is proposed.

“…Loyal to his mainstream idea that a better knowledge could be obtained with a multidisciplinary approach, he used many species instead of a single one for thermo-microbiological studies. With such approach, he was able to describe different relations of thermal death and exponential growth, which corresponded to two distinct death processes among yeasts species (11). In this line, he observed that most yeasts generally growing at higher temperatures, showed a temperature range (e.g., 36-448C, for Saccharomyces cerevisiae) where thermal death and growth concurred, and designated them as associatively profiled yeasts.…”
