Psychrotrophic proteolytic bacteria from cold environment of Gangotri glacier, Western Himalaya, India

Recovery of metallo-tolerant and antibiotic resistant psychrophilic bacteria from Siachen glacier, Pakistan

“…Scientists have discovered that glaciers can be a favorable environment to support active and diverse communities of micro- as well as macrobiota [9, 10]. The presence of bacteria in polar and non-polar glaciers have been reported by many researchers through both culture-dependent and culture-independent techniques [11–13]. Dormant and vegetative forms of bacteria exist under ice of glacier and are adapted to this unique ecosystem by one or more diverse mechanisms [14].…”

Extracellular cold-active lipase of Microbacterium luteolum isolated from Gangotri glacier, western Himalaya: Isolation, partial purification and characterization

“…Psychrophiles and psychrotrophic organisms play a major role in degradation of organic matter in microbial ecosystem of Gangotri glacier. Thus, it would be of much interest to study nature of extracellular enzyme such as lipase secreted by cold adapted bacteria that are active not only in permanently cold areas but in habitats which experiences temperature fluctuation [2]. Some of these organisms depending on their optimal growth temperature are also known as psychrotolerant or psychrotrophs [28].…”

Seasonal variation of snow microbial community structure in the East Rongbuk glacier, Mt. Everest

“…Xiong et al isolated yeasts from two snow samples in Xixiabangma Peak, Himalaya [9] and revealed that the number of bacteria were 6.9×10 6 and 17.9×10 6 cells/mL −1 , respectively. Baghela et al [10] studied proteolytic bacteria in the cold Gangotri glacier, Western Himalaya, India. Yoshitaka et al [11] examined the snow algae in a Himalayan glacier and the changes of algal biomass and community structure along the altitude gradient.…”
