Xerophilic and xerotolerant microfungi were isolated from soil samples collected in Anapurna Mountains, Nepal, at altitudes from 3000 to 5400 m. The total numbers and proportions of xerotolerant and psychrophilic strains in comparison with mesophilic mycobiota were determined by using different enumeration, selective media and four isolation methods. The most extreme xerophilic fungi were taxonomically identified as belonging to the genera Eurotium and Aspergillus. The low water activity of the soil due to dry climate and frequent binding of water in ice crystals favors a high proportion of xerotolerant fungal species. The correlation between xerotolerant and psychrophilic fungi was observed.
从尼泊尔安纳布尔纳山脉海拔3000至5400米处采集的土壤样本中分离出嗜干和耐干微真菌。通过使用不同的计数方法、选择性培养基和四种分离方法，确定了耐干和嗜冷菌株与中温真菌群落相比的总数和比例。分类学鉴定表明，最极端的嗜干真菌属于曲霉属和青霉属。干燥气候导致土壤水分活性低，且水分频繁冻结，这有利于耐干真菌物种的高比例存在。观察到了耐干真菌与嗜冷真菌之间的相关性。
