Three novel bacterial strains, PVAS-1(T), B3W22(T) and B8W22(T), were isolated from cryotubes used to collect air samples at altitudes of between 27 and 41 km. Based on phenotypic characteristics, chemotaxonomic features, DNA-DNA hybridization with the nearest phylogenetic neighbours and phylogenetic analysis based on partial 16S rRNA gene sequences (PVAS-1(T), 1196 nt; B3W22(T), 1541 nt; B8W22...

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), are very similar to one another (>98 % s...

Polyaromatic hydrocarbons (PAHs) with high molecular weight (more than three benzene rings) were difficult to degrade in saline environment. The present study details about the bacterial consortium enriched from industrial sludge from salt manufacturing company, Tuticorin, Tamilnadu (India), which was capable of degrading 1, 4 dioxane (Emerging micropollutant) and also phenanthrene as sole carb...

The present study focus on the biodegradation of trinitrotoluene (TNT) by Bacillus sp. YRE1 isolated from red effluent in free state and also cells immobilized on charcoal and polystyrene. TNT degradation was monitored weekly for 168 hours, at 262 nm. Immobilized Bacillus sp. YRE1 was checked for its ability to degrade TNT by exposing it to different temperatures. It was found that both charcoa...

Pseudomonas sp. strain ADP contains the genes, atzA, -B, and -C, that encode three enzymes which metabolize atrazine to cyanuric acid. Atrazine-catabolizing pure cultures isolated from around the world contain genes homologous to atzA, -B, and -C. The present study was conducted to determine whether the same genes are present in an atrazine-catabolizing bacterial consortium and how the genes an...

The alkaliphilic hemicellulolytic bacterium Bacillus sp. N16-5 has a broad substrate spectrum and exhibits the capacity to utilize complex carbohydrates such as galactomannan, xylan, and pectin. In the monosaccharide mixture, sequential utilization by Bacillus sp. N16-5 was observed. Glucose appeared to be its preferential monosaccharide, followed by fructose, mannose, arabinose, xylose, and ga...

The alkaliphilic halotolerant bacterium Bacillus sp. N16-5 is often exposed to salt stress in its natural habitats. In this study, we used one-colour microarrays to investigate adaptive responses of Bacillus sp. N16-5 transcriptome to long-term growth at different salinity levels (0%, 2%, 8%, and 15% NaCl) and to a sudden salt increase from 0% to 8% NaCl. The common strategies used by bacteria ...

A total of 540 one-day old male broilers Ross 308 were allocated to 6 treatments in a completely randomized designed with a 2×3 factorial arrangement (aflatoxin B1 (AFB1) and probiotics) with 6 replicates and 15 birds in each. Factors include aflatoxin B1 (control, 500 ppb) and probiotics (control, 108 cfu/mL Bacillus sp. MBIA2.40, 0.2 g Gallipro per kg). Results showed that adding 500 ppb AFB1...

A phage, designated CP-51, that carries out generalized transduction in Bacillus cereus and B. anthracis, has recently been isolated from soil. Transducing phages for members of the genus Bacillus have been described previously for B. subtilis and B. licheniformis (2-6). Those that have been best characterized are PBS-1 for B. subtilis (4) and SP-10 and SP-15 for both B. subtilis and B. licheni...

Takahashi, I. (McMaster University, Hamilton, Ontario, Canada). Localization of spore markers on the chromosome of Bacillus subtilis. J. Bacteriol. 89:1065-1067. 1965.-Attempts were made to locate spore markers on the chromosome by determining the mapping distance of ery(r), str(r), phe, tyr, and ser markers to which the spore markers are closely linked. The results obtained indicated that locu...
