Bacterial diversity of soil samples from the western Himalayas, India.
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-independentExpand

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 onExpand

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 beExpand

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 kDaExpand

Effect of propionate toxicity on methanogenesis of night soil at phychrophilic temperature.
The effect of propionate concentrations on biodegradation of human waste (night soil) was studied at 10 degrees C. Propionate was toxic for the biomethanation at all the pH tested (6.0, 7.0 and 8.0).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 ofExpand
