CMS 19YT, a psychrophilic bacterium, was isolated from a cyanobacterial mat sample from a pond in Antarctica and was characterized taxonomically. The bacterium was aerobic, gram-positive, non-spore-forming, non-motile, exhibited a rod-coccus growth cycle and produced a yellow pigment that was insoluble in water but soluble in methanol. No growth factors(More)
Ten cultures of Pseudomonas spp. were established from soil samples collected in and around a lake in Antarctica. Based on their morphology, biochemical and physiological characteristics, and moles percent G + C of their DNA, they were identified as P. fluorescens, P. putida, and P. syringae. This is the first report on the identification of Pseudomonas(More)
The bacterial diversity of a soil sample collected in the vicinity of Lake Zub, Schirmacher Oasis, Antarctica, was determined both by establishing pure colonies of culturable bacteria and by cloning the total 16S rDNA of the soil and establishing the phylogeny of the clones. Analysis of the 16S rRNA gene clones indicated that the bacteria belonged to the(More)
Strain DVS 5a1 was isolated from a moraine sample from the McMurdo Dry Valleys region of Antarctica. The strain is aerobic, Gram-positive, with white aerial mycelia and brown substrate mycelia, sporulating, has meso-diaminopimelic acid, arabinose and galactose in the cell wall, MK-8 (H4) as the major menaquinone and a mol% G+C content of DNA of 71% thus(More)
An arsenic- and radiation-resistant bacterium, strain Wt/1a(T), was isolated from water from an arsenic-contaminated aquifer located in the Chakdah district of West Bengal, India. The bacterium stains Gram-negative and is rod-shaped, non-motile, non-sporulating and red-pigmented. Cell-wall peptidoglycan contains ornithine as the diamino acid, MK-8 is the(More)
Strain HHS 22(T) was isolated from a glacial water sample from the snout of the Hamta glacier located in the Himalayan mountain ranges of India. Phenotypic, chemotaxonomic and phylogenetic analyses established the affiliation of the isolate to the genus Pedobacter. HHS 22(T) exhibits high 16S rRNA gene sequence similarity with Pedobacter cryoconitis (98 %).(More)
Strain PN5(T) is a Gram-positive, aerobic, motile, rod-shaped, peritrichously flagellated bacterium that was isolated from the Pindari glacier using nutrient agar medium. Cells of PN5(T) are catalase-positive and oxidase-negative and contain lysine, glutamic acid and alanine in the peptidoglycan (peptidoglycan type A4alpha). Further, the cells are(More)
Three 16S rRNA gene clone libraries (P1L, P4L and P8L) were constructed using three soil samples (P1S, P4S and P8S) collected near Pindari glacier, Himalayas. The three libraries yielded a total of 703 clones. Actinobacteria, Firmicutes and Proteobacteria were common to the three libraries. In addition to the above P1L and P8L shared the phyla(More)
Four novel bacterial strains were isolated from cryogenic tubes used to collect air samples at altitudes of 24, 28 and 41 km. The four strains, 24K(T), 28K(T), 41KF2a(T) and 41KF2b(T), were identified as members of the genus Bacillus. Phylogenetic analysis based on 16S rRNA gene sequences indicated that three of the strains, 24K(T), 28K(T) and 41KF2a(T),(More)
Strain HHS 11(T) was isolated from a water sample collected from the snout of Hamta glacier located in the Himalayan mountain ranges of India. Phenotypic, chemotaxonomic and phylogenetic analyses established the affiliation of the isolate to the genus Dyadobacter. HHS 11(T) possessed 96 and 95% 16S rRNA gene sequence similarity with respect to Dyadobacter(More)
