Starmerella fangiana f.a. sp. nov., a new ascomycetous yeast species from Daqu-making environment and other sources
In the survey of yeast diversity in high-temperature Daqu, which is a fermentation starter for Chinese sauce-flavoured Baijiu, six yeast strains representing one novel species of the genus <i>Starmerella</i> were isolated from samples of Daqu and surrounding environments collected in Zunyi city, Guizhou Province, China. Phylogenetic analyses of the internal transcribed spacer (ITS) region and the D1/D2 domains of the large subunit rRNA gene indicate that these six strains are conspecific with three other strains isolated from flowers and duckweed collected in Samoa, India and Thailand. The representative strain QFC-8 of the new species differs from the closet species <i>Starmerella caucasica</i> resolved by the D1/D2 sequence analysis by 13 (3.1 %, 12 substitutions and 1 gap) and 40 (10.3 %, 9 substitutions and 31 gaps) mismatches in the D1/D2 domain and ITS region, respectively. The results suggest that the novel group represents an undescribed species in the genus <i>Starmerella</i>, for which the name <i>Starmerella fangiana</i> sp. nov. is proposed. The holotype strain is CGMCC 2.7773.
