Abstract

The genus belonging to the family Pichiaceae is widely distributed worldwide and has garnered significant attention due to its importance in various industries and its potential role in human infections. During our investigation of yeast diversity in China, several strains representing undescribed taxa were isolated from forests in Hainan province, Hubei province, Beijing city and a mudflat in Guangdong province. Based on phylogenetic analyses of the internal transcribed spacer (ITS) region and the D1/D2 domain of the large subunit (LSU) rRNA, these strains were identified as four new species: (holotype strain CGMCC 2.7383), (holotype strain CGMCC 2.8239), (holotype strain CGMCC 2.6825) and f.a. (holotype strain CGMCC 2.7381). The six strains of were identified as positive for urease production. This phenomenon is extremely rare in the genus , as only is reported to exhibit weak urease activity.

摘要

属于皮氏菌科的该属在全球广泛分布，因其在各个行业中的重要性及其在人类感染中的潜在作用而备受关注。在我们对中国酵母多样性的调查中，从海南省、湖北省、北京市的森林以及广东省的一个泥滩中分离出了几株代表未描述分类单元的菌株。基于对内部转录间隔区（ITS）区域和大亚基（LSU）rRNA的D1/D2结构域的系统发育分析，这些菌株被鉴定为四个新物种： （模式菌株CGMCC 2.7383）、 （模式菌株CGMCC 2.8239）、 （模式菌株CGMCC 2.6825）和f.a. （模式菌株CGMCC 2.7381）。六株 菌株被鉴定为脲酶产生阳性。这种现象在该属中极为罕见，因为据报道只有 表现出微弱的脲酶活性。
