摘　　要：从含糖量高的自然界样品中分离获得1株耐高渗酵母NH-9,在对其常规形态学及生理生化特性鉴定的基础上,对部分长度的18S rDNA同源性进行了分析,发现NH-9菌株与奥默柯达菌相似度100%,命名为Kodamaea ohmeri NH-9,这也是首次发现此属酵母能够产生D-阿拉伯糖醇。An osmophilic yeast NH-9 producing D-arabitol was isolated from natural sugary niches. In addition to general physiological and biochemical properties, NH-9 was identified by 18S rDNA sequences and systematic analysis. The results indicated that 18S rDNA sequence of this strain had 100% similarity with the partial sequence of Kodamaea ohmeri, suggesting that the strain is a subspecies of Kodamaea ohrneri, and denominated as K. ohmeri NH-9. To our knowledge, this is the first report of D-arabitol production from glucose by K. ohmeri in literature.
