In an attempt to screen out cellulase producing bacteria from herbivorous animal fecal matter it was possible isolate a potent bacterium cow dung. The identified as Bacillus sp. using 16S rDNA based molecular phylogenetic approach. effect of different agricultural wastes, paper wastes and carboxymethyl cellulose on endoglucanase production tested found produce maximally at 8% cellulose. precipitated by ammonium sulfate saturation purified DEAE- Sepharose column. purification achieved 8.5...
A polyphasic approach was used to characterize a bacterium, GPTSA 11(T), isolated from warm spring located in reserve forest Assam, India. The cells are Gram-variable, strictly aerobic, sporulating motile rods. major fatty acids of the strain C(15 : 0) anteiso (48.42 %), C(16 iso (11.59 1)omega11c (6.16 (6.03 C(17 (5.68 %) and 1)omega7c alcohol (5.01 %). presence acid distinguishes this other closely related species genus Paenibacillus. contains MK-7 as diagnostic menaquinone. G+C content...
A buff-yellow-pigmented bacterium, strain K22-20 T , which was isolated from a cold desert of the Indian Himalayas, subjected to polyphasic taxonomic study. Phenotypic and chemical properties were consistent with its classification in genus Ornithinimicrobium . The major fatty acids iso-C 17 : 1 ω 9 c ( cis -15-methyl 7-hexadecenoic acid), 15 0 (13-methyl tetradecanoic 16 (14-methyl pentadecanoic acid) (15-methyl hexadecanoic acid). G+C content genomic DNA 71 mol%. According 16S rRNA gene...
In the course of a study prokaryotic diversity landfill site in Chandigarh, India, strain designated SK 55T was isolated and characterized using polyphasic approach. Its 16S rRNA gene sequence showed closest similarity (98.3 %) to that Sporosarcina macmurdoensis CMS 21wT. The strains other hitherto described species less than 95.5 %. Strain contains peptidoglycan A4α type (l-Lys–d-Asp), MK-8 MK-7 as major menaquinones iso-C15 : 0 fatty acid. 55T, ureae, genus, had some polar lipids common...
An aquatic bacterium, strain GPTSA100-15T, was isolated on nutritionally poor medium TSBA100 (tryptic soy broth diluted 100 times and solidified with 1.5 % agarose) characterized using a polyphasic approach. The isolate unable to grow commonly used rich media such as tryptic agar, nutrient agar Luria-Bertani agar. Phylogenetic analysis based 16S rRNA gene sequences revealed that the affiliated family 'Flexibacteraceae' in phylum Bacteroidetes. Phylogenetically, it showed closest similarity...
A bacterial strain designated GPTSA 20(T), which was isolated from a warm spring in Assam, India, characterized by using polyphasic approach. The cells were Gram-negative, aerobic rods, could not utilize or produce acid most of the carbohydrates tested. predominant fatty acids C(15:0) iso (25.04%), C(17:1) omega9c (19.28%), C(16:0) (17.73%) and C(11:0) 3-OH (9.34%). G+C content 75 mol%. From 16S rRNA gene sequence analysis (1433 nucleotides, continuous stretch), it confirmed that 20(T)...
The taxonomic position of an actinomycete, strain K07-23T, isolated from a cold desert the Himalayas, India, was established by polyphasic approach. exhibited phenotypic characters that were typical genus Rhodococcus. 16S rRNA gene sequence (1467 bases) comparisons confirmed K07-23T belongs to similarity studies showed isolate is very closely related Nocardia corynebacterioides DSM 20151T (98.6 %), which has been recently reclassified as Rhodococcus corynebacterioides. It 94.4-96.6 % with...
A Gram-negative, facultatively anaerobic bacterial strain designated GPTSA-6 T was isolated from a water sample collected warm spring in Assam, India. Preliminary analysis of the 16S rRNA gene sequence this isolate revealed its affiliation to family Aeromonadaceae . Detailed characterization using polyphasic approach indicated that is most closely related Aeromonas sobria but differs significantly existing members genus Analysis almost-complete (1430 nt) closest relative (99.23 % similarity)...
A novel facultatively anaerobic strain, designated GPTSA 19 T , was isolated from a warm spring and characterized using polyphasic approach. The strain behaved as Gram-negative in the Gram staining procedure but showed Gram-positive reaction aminopeptidase test. mesophilic rod with ellipsoidal endospores. On basis of 16S rRNA gene sequence analysis, closest similarity (96.0 %) Paenibacillus motobuensis MC10 . other species genus <95.8 %. also had PAEN 515F 682F signature stretches that...
Rhodococcus sp. strain BUPNP1 can utilize the priority environmental pollutant 4-nitrophenol (4-NP) as its sole source of carbon and energy. In this study, genome transcriptome sequencing were used to gain mechanistic insights into 4-NP degradation. The draft is 5.56 Mbp encodes 4,963 proteins, which are significantly enriched in hypothetical proteins compared other A novel catabolic 43 gene cluster 'nph' was identified that all genes required for conversion acetyl-CoA succinate, via...
A polyphasic taxonomic approach was employed to characterize a strain designated GPTSA100-9 T , which isolated from water sampled warm spring. The micro-organism, comprising Gram-negative, strictly aerobic rods, could not grow on nutritionally rich media such as tryptic soy broth. Analysis of the 16S rRNA gene sequence (1396 nt) revealed that it is member genus Flavobacterium sharing 99.8 % similarity with CFB group bacterium A0653 (AF236016), 93.4 ‘[ Flexibacter ] aurantiacus subsp....
An organophosphate (OP) degrading chemotactic bacterial strain BUR11 isolated from an agricultural field was identified as a member of Pseudomonas genus on the basis its 16S rRNA gene sequence. The could utilize parathion, chlorpyrifos and their major hydrolytic intermediates sole source carbon for growth exhibited positive response towards most them. Optimum concentration parathion recorded to be 200 ppm 62% which degraded within 96 h at 37 °C. Growth studies indicated moderately...
Polyphasic characterization of an actinomycete strain VT-36 T isolated from a sugar-cane field soil sample collected in Punjab State, India, revealed that the belongs to genus Kitasatospora . The strain's chemotaxonomic characters and G+C content DNA (76·5 mol%) were typical members genus. Analysis 16S rRNA gene sequence supported generic affiliation showed its closest phylogenetic relative was putterlickiae F18-98 (=DSM 44665 ) (98·3 % similarity). similarities with type strains all other...
