Zygotorulaspora chibaensis sp. Nov. and zygotorulaspora danielsina sp. nov., novel ascomycetous yeast species from tree bark and soil

Abstract

Multiple isolates belonging to the ascomycetous genus Zygotorulaspora were obtained from forest soils and tree bark in Shiba Prefecture in Japan, and Lake Daniels, Lewis Pass, in New Zealand. Phylogenetic analyses employing combined sequences of the D1/D2 domain and ITS region support the recognition of two new species:Zygotorulaspora chibaensis sp. nov. (type strain PYCC 6970T =CBS 15364T) and Zygotorulaspora danielsina sp. nov. (type strain PYCC 6984T =CBS 15365T). Both species are able to grow on D-xylose and L-arabinose and at 35° C, unlike Zygotorulaspora florentina and Zygotorulaspora mrakii, the other two species in the genus.
