【摘要】 从新疆28个市(县)收集到的52份果园土壤中分离出198株酵母菌,根据菌落形态学特征挑取部分菌株,结合细胞形态学和26S rDNA D1/D2序列分析进行鉴定,共鉴定出12属29个种(或变种),其中优势属为假丝酵母属Candida、毕赤酵母属Pichia和隐球酵母属Cryptococcus,广布种为Galactomyces geotrichum和Issatchenkia orientalis。经与国内已发表的酵母种类比较,发现中国新纪录种6个,分别为分离于喀什泽普Cryptococcus uzbekistanensis,哈密的Issatchenkia occidentalis,分离于吐鲁番鄯善、石河子、博乐精河的Issatchenkia terricola,博乐精河的Pichia mexicana,库尔勒、博乐精河的Phichia galeiformis,奇台的Rhodosporidium kratochvilovae。更多还原

【Abstract】 198 yeast strains were isolated from 52 soil samples of grape orchards,collected from 28 autonomous prefectures or counties of Xinjiang,then parts of the strains were selected according to morphological characteristics.Among them 29 species(or varieties)belonging to 12 genera were identified based on the combination of 26S rDNA D1/D2 domain sequence analysis and morphology,and some physiological characterizations.The dominant genera identified were Candida,Pichia and Cryptococcus.Galactomyces geotrichum and Issatchenkia orientalis were the most widely species distributed naturally.Compared with yeast species published in China at home,6 China new record species were discoverd which were Cryptococcus uzbekistanensis from Kashi,Issatchenkia occidentalis from Hami,Issatchenkia terricola from Turpan,Shihezi and Bole,Pichia mexicana from Bole,Phichia galeiformis from Kuerle and Bole,Rhodosporidium kratochvilorae from Qitai,respectively.更多还原
