摘要

本次研究工作的主要目的是研究喜马拉雅地区Garhwal三个重要冰川口部冰样的物理化学性质以及嗜冷微生物的多样性。本研究从2015年到2016年进行了两年,每年两次抽样尝试。在所有预先确定的采样点深度5cm处采集冰样,观察和记录冰样特征,分离和鉴定微生物的嗜冷多样性。总共记录了14种冰样品的物理和化学性质。通过形态学、生物化学和MALDI-TOF-MS技术鉴定了其嗜冷微生物的多样性。Satopanth冰川冰面微生物α -多样性为17,细菌种类为08种,放线菌种类为04种,真菌种类为05种。而Bhagirathi-Kharak冰川冰中微生物的α -多样性也为17,有06种细菌、05种放线菌和06种真菌。Gangotri冰川冰中微生物α -多样性为19,细菌09种,放线菌05种,真菌05种。目前的研究工作可以为类似学科的其他研究提供一个体面的参考。现有的数据还将帮助研究人员研究嗜冷动物,它们在冰川中的存在以及它们对社会的重要性。

PSYCHROPHILIC MICROBIAL DIVERSITY AND PHYSICOCHEMICAL CHARACTERISTICS OF GLACIERS IN THE GARHWAL HIMALAYA, INDIA
The main objective of the current research work was to investigate the physicochemical properties of ice samples collected from the snout of three important glaciers located in the Garhwal Himalaya along with the psychrophilic microbial diversity. This study was carried out for two years from 2015 to 2016 with two sampling attempts each year. Ice samples were collected from all the pre-identified sampling sites at a depth of 5cm to observe and record the characteristics and to isolate and identify the psychrophilic diversity of microorganisms. Overall fourteen physical and chemical properties of ice samples were recorded. The psychrophilic microbial diversity was identified through the morphological, biochemical and MALDI-TOF-MS techniques. The α–diversity of microbes in the ice of Satopanth glacier was 17 with 08 bacterial species, 04 actinomycetes species and 05 fungal species. However, the α–diversity of microbes in the ice of Bhagirathi-Kharak glacier was also 17 with 06 bacterial species, 05 actinomycetes species and 06 fungal species. The α–diversity of microbes in the ice of Gangotri glacier was 19 with 09 bacterial species, 05 actinomycetes species and 05 fungal species. The present research work can be a decent reference for additional investigations in a similar discipline. The available data will also help the researchers to study the psychrophiles, their existence in glaciers and their importance to society.
