Candida nonsorbophila sp. nov., a new ascomycetous yeast species isolated in Thailand

摘要

Four yeast strains, RS42, SSK10, ST-520 and ST-521, isolated from water in a mangrove forest, bark of a tree and fruit of Ficus sp., respectively, were found to represent a hitherto undescribed anamorphic species. The four strains are related to Candida sinolaborantium in the D1/D2 domain of the large subunit rRNA gene, but differed by eight nucleotide substitutions and two indels, and for this reason are regarded as members of a separate species. Because ascospore formation was not detected, it is described as a new species of Candida, Candida nonsorbophila sp. nov. The type strain is RS42(T) (BCC 25963(T)=NBRC 103860(T)=CBS 10862(T)). This species is distinguished from C. sinolaborantium by the inability to assimilate L-sorbose, L-rhamnose and galactitol, and a higher maximum growth temperature.
