摘要

Water samples were collected from two different glacier-fed lakes located at a very high altitude in the Garhwal Himalayan region of Uttarakhand for two continuous years 2014-2015. Water samples were collected at a depth of 10 cm in two sampling operations each year. This was done to isolate and identify the psychrophilic microbial diversity including bacteria, actinomycetes and fungi. Apart of the microbial diversity, a total of eighteen physical and chemical environmental variables were recorded from the water samples collected in two different glacier-fed lakes. In the water samples collected from the Satopanth Lake, a total of six bacterial species, four actinomycetes species and five species of fungi were recorded. On the other hand, seven bacterial species, five actinomycetes species and four species of fungi were recorded in the water samples collected from the Neel Tal. This pivotal study on the assessment of physicochemical characteristics and psychrophilic microbial diversity of both the glacier-fed lakes can be a good reference for further study on the similar aspects. The available data will also help the government and policy makers to adjust policies for the conservation and management of both lakes, as these lakes provide essential water resources to nearby residents, tourists, sages, trekkers and wild animals for consumption and various recreation activities.

本研究於2014－2015連續兩年從位於北阿坎德邦的喜馬拉雅高瓦區的兩個高海拔冰川湖收集水樣，每年兩次的採樣皆於深度10公分處進行，旨在分離和鑑定包括細菌、放線菌和真菌在內的嗜冷微生物的多樣性。除微生物多樣性外，於兩個冰川湖收集的水樣中總共發現並記錄了18個理化環境變量。Satopanth湖的水樣中發現了總共6種細菌，4種放線菌和5種真菌。Neel Tal湖的水樣中則包含了7種細菌，5種放線菌和4種真菌。這項針對兩個冰川湖的理化特徵和嗜冷微生物多樣性評估的前衛研究有助於未來相關方面進一步的研究。Satopanth湖和Neel Tal湖為附近的居民、遊客、僧人、徒步旅人以及野生動物提供可消耗的水資源及其他休閒娛樂活動，而研究中所收集的數據資料也可以從而協助政府和政策制定相關人員擬定兩個冰川湖的保護與管理策略。
