Six novel yeast species, Starmerella camargoi f.a., sp. nov., Starmerella ilheusensis f.a., sp. nov., Starmerella litoralis f.a., Starmerella opuntiae f.a., sp. nov., sp. nov., Starmerella roubikii f.a., sp. nov. and Starmerella vitae f.a, sp. nov. are proposed to accommodate 19 isolates recovered from ephemeral flowers or bees in Brazil, Costa Rica and Belize. Sequence analysis of the ITS-5.8S region (when available) and the D1/D2 domains of the large subunit of the rRNA gene showed that the six novel yeasts are phylogenetically related to several species of the Starmerella clade. The type strains are Starmerella camargoi f.a., sp. nov. UFMG-CM-Y595 (=CBS 14130; Mycobank number MB 822640), Starmerella ilheusensis f.a., sp. nov. UFMG-CM-Y596 (=CBS CBS14131; MB 822641), Starmerella litoralis f.a., sp. nov. UFMG-CM-Y603 (=CBS14104; MB 822642), Starmerella opuntiae f.a., sp. nov. UFMG-CM-Y286 (=CBS 13466; MB 822643), Starmerella roubikii f.a., sp. nov. UWOPS 01-191.1 (=CBS 15148; MB 822645) and Starmerella vitae f.a., sp. nov. UWOPS 00-107.2 (=CBS 15147; MB 822646). In addition, 25 species currently assigned to the genus Candida are reassigned formally to the genus Starmerella.

To investigate the microbial diversities and dynamic quality properties of kombucha, the successional changes with different periods from four regions were comprehensively characterized and compared. A total of 197 indigenous yeast and bacterial strains were isolated, involving Gluconobacter, Komagataeibacter, Starmerella and Zygosaccharomyces spp. The successional dynamics of the kombucha communities in different regions were evaluated.

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 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 resolved by the D1/D2 sequence analysis by 13 (3.

Glycolipid biosurfactant, sophorolipids (SLs) and rhamnolipids (RLs) can be widely used in agriculture, food and chemical industries. The different physicochemical properties of SLs and RLs, such as hydrophilic lipophilic value (HLB) and critical micelle concentration (CMC), determine they have different application focus. Researchers are still hoping to obtain new glycolipid surfactants with unique surface activities.

Four yeast isolates collected from flowers from different ecosystems in Brazil, one from fruit of in Argentina, three from flowers of in Chile and one obtained from the proventriculus of a female bumblebee in Canada were demonstred, by analysis of the sequences of the internal transcribed spacer (ITS) region and D1/D2 domains of the large subunit rRNA gene, to represent two novel species of the genus . These species are described here as f.a, sp.
