High-altitude cold habitats of the Himalayas are little explored with respect to bacterial diversity. Diverse bacterial species and phylotypes obtained by culture-dependent and culture-independent… Expand
Biomethanation under psychrophilic conditions.
The biomethanation of organic matter represents a long-standing, well-established technology. Although at mesophilic and thermophilic temperatures the process is well understood, current knowledge on… Expand
Effect of various carbon and nitrogen sources on cellulose synthesis by Acetobacter xylinum
The effect of various carbon and nitrogen sources on cellulose membrane production by Acetobacter xylinum was evaluated. Among the carbon sources, sucrose, glucose and mannitol were found to be… Expand
Purification and characterisation of extracellular protease produced by Clostridium sp. from Schirmacher oasis, Antarctica
One anaerobic, proteolytic bacterium isolated from Schirmacher oasis, Antarctica was characterised taxonomically. Based on morphology, biochemical characteristics and 16S rRNA sequence the isolate… Expand
Purification and characterization of thermo-labile alkaline phosphatase from an Antarctic psychrotolerant Bacillus sp. P9
A psychrotolerant Bacillus sp. from Antarctica produced an alkaline phosphatase in the culture supernatant. The strain showed 98.4% 16s rDNA sequence identity with Bacillus sphaericus. The 76 kDa… Expand

Production of biogas from night soil at psychrophilic temperature
Abstract Anaerobic digestion of night soil was carried out in a 25 l digester at 10°C using an adapted inoculum. Biogas production was studied at 20, 25, 30, 35 and 40 days hydraulic retention time.… Expand
Proteolytic heterotrophic bacteria of cyanobacterial assemblage from Schirmacher oasis, Antarctica, capable of growing under extreme conditions
Physiologically diverse groups of bacteria were isolated from cyanobacterial assemblages of Schirmacher oasis Antarctica. Psychrotrophs have been the most dominant, with little population of… Expand
