摘要
A new ascomycetous yeast species, Kazachstania jiainicus, is proposed based on two strains isolated from soil in Taiwan. The species is characterized by forming one or two globose spores in each ascus, fermenting glucose and galactose and assimilating few carbon and nitrogen compounds. Genus assignment and distinction of the strains from recognized species is based on ascosporulation and phylogenetic analysis of nucleotide sequences from domains D1/D2 of the large subunit (26S) rRNA gene. Sequence analysis showed that the species was phylogenetically related to the genus Kazachstania. The species was distinct from recognized species of Kazachstania on the basis of carbon and nitrogen assimilation patterns. Based on the characteristics described above, the species is recognized as a novel species of the genus Kazachstania, and the name Kazachstania jiainicus sp. nov. is proposed. The type strain is SF1S05 T (=CBS10587 T =NBRC 102655 T =BCRC 23098 T ), which was isolated from soil in Jiain, Hualein, Taiwan. © 2007 Federation of European Microbiological Societies.
