Ascoidea xinghuacunensis sp. nov., a novel ascomycetous yeast species from Xinghuacun Fenjiu old workshop, Shanxi province of China.

Abstract

Four yeast strains belonging to the ascomycetous yeast genus Ascoidea were isolated from the mixture of remnants of steamed sorghum, Daqu powder and the fermented grain that fell off during transportation on the ground in the workshop which were collected in Xinghuacun Fenjiu old workshop, Shanxi province, PR China. We propose the name Ascoidea xinghuacunensis sp. nov. (holotype: strain CGMCC 2.7787) for the new species, which differs phenotypically from the other three species in this genus: Ascoidea asiatica, Ascoidea rubescens and Ascoidea tarda by its ability to grow at 37 °C. This study represents the first isolation of Ascoidea species within the borders of China and the initial report of the Ascoidea species detailing the isolation from the Baijiu brewing environment.
