采用平板分离法,从29 份新鲜采集的土样中分离获得64 株耐高温酵母菌株,并对其在高温条件下的乙醇发酵性能进行了分析比较.26S rDNA D1/D2区域序列测定和生理特征分析结果表明,这些酵母菌株在亲缘关系上可归类于6 个属7 个种,分别为热带假丝酵母（Candida tropicalis）（占总分离株的39.1%）、马克斯克鲁维酵母（Kluyveromyces marxianus）（占23.4%）、东方伊萨酵母（Issatchenkia orientalis）（占29.7%）、季也蒙毕赤酵母（M. guilliermondii）（占1.6%）、Kazachstania bovina（占1.6%）、Candida palmioleophila（占1.6%）和酿酒酵母（Saccharomyces cerevisiae）（占3.1%）.其中,马克斯克...

In this study, 69 thermotolerant yeast strains were isolated from 29 different soil samples, and the fermentation performance of these strains at high temperature was also detected. Based on 26S rDNA D1/D2 domain sequence analysis and physiological characterization, these strains were phylogenetically related to 7 species in 6 genera, including Candida tropicalis (39.1% of the total yeast strains), K. marxianus (23.4%), I. orientalis (29.7%), M. guilliermondii (1.6%), K. bovina (1.6%), C. palmioleophila (1.6%) and S. cerevisiae (3.1%). C. tropicalis were the most widely distributed species. Th...
