Abstract

Five yeast strains were isolated from soil and moss samples from the Livingston Island (Antarctica) and identified according to morphological cultural and physiological characteristics. All strains had an optimum growth temperature of 15 degrees C: none grew above 25 degrees C. They assimilated D-glucose, D-galactose, sucrose, cellobiose, trehalose, 2-keto-D-gluconate, D-xylose, D-ribose and melezitose. Four of them were nonfermentative, only one, which formed pseudomycelium fermented glucose, galactose, trehalose. Two strains were identified as pink-red yeasts belonging to genus Rhodotorula--R. minuta and R. mucilaginosa; two were related to the genus Cryptococcus--C. albidus and C. laurentii; one was Candida oleophila.

摘要

从南极利文斯顿岛的土壤和苔藓样本中分离出五株酵母菌株，并根据形态培养和生理特征进行鉴定。所有菌株的最适生长温度为15摄氏度：在25摄氏度以上均不生长。它们能同化D-葡萄糖、D-半乳糖、蔗糖、纤维二糖、海藻糖、2-酮-D-葡萄糖酸盐、D-木糖、D-核糖和松三糖。其中四株为非发酵型，只有一株形成假菌丝，能发酵葡萄糖、半乳糖、海藻糖。两株被鉴定为属于红酵母属的粉红-红色酵母——微小红酵母和粘红酵母；两株与隐球菌属有关——浅白隐球菌和罗伦隐球菌；一株是嗜油假丝酵母。
