| dynamics of bacterial class bacilli in the deepest valley lake of kashmir-the manasbal lake. | in recognition of the importance of bacteria as ecological indicators of the aquatic systems a comprehensive and systematic analysis was carried out on manasbal lake, the deepest spring fed valley lake of kashmir. the main objective envisaged was to analyze bacterial community composition (bcc) and for this purpose systematic and regular sampling of waters from ten different sampling stations, predetermined in the lake according to differences in degree of human interference and also as zones of ... | 2017 | 28087491 |
| bacillus aerius sp. nov., bacillus aerophilus sp. nov., bacillus stratosphericus sp. nov. and bacillus altitudinis sp. nov., isolated from cryogenic tubes used for collecting air samples from high altitudes. | 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 % sequence similarity) and show a similarity of 98-99 % with bacillus licheniformis and 98 % with bacillus ... | 2006 | 16825614 |
| isolation and characterization of methane utilizing bacteria from wetland paddy ecosystem. | methylotrophic bacteria which are known to utilize c1 compounds including methane. research during past few decades increased the interest in finding out novel genera of methane degrading bacteria to efficiently utilize methane to decrease global warming effect. moreover, evaluation of certain known plant growth promoting strains for their methane degrading potential may open up a new direction for multiple utility of such cultures. in this study, efficient methylotrophic cultures were isolated ... | 2014 | 24469547 |
| characterization of a salt-tolerant bacterium bacillus sp. from a membrane bioreactor for saline wastewater treatment. | high salt concentrations can cause plasmolysis and loss of activity of cells, but the salt-tolerant bacterium can endure the high salt concentrations in wastewater. in this research 7 salt-tolerant bacteria, which could survive in dry powder products and could degrade organic contaminants in saline wastewater, were isolated from a membrane bioreactor. the strain ny6 which showed the fastest growth rate, best property for organic matter degradation and could survive in dry powder more than 3 mont ... | 2014 | 25079850 |
| purification and physicochemical properties of lipase from thermophilic bacillus aerius. | a thermophilic bacterial isolate producing lipase was isolated from soil of hot spring and identified as bacillus aerius (mtcc 10978). peak lipase activity was observed when 30 h old inoculum was used and incubated in shaking conditions for 48 h. the optimal temperature and ph for the bacterial growth and lipase production was found to be 55°c and 8.0 respectively with cottonseed oil as carbon source, yeast extract and beef extract as nitrogen source. the enzyme produced by thermophilic bacillus ... | 2014 | 25391687 |
| the status of the species bacillus aerius. request for an opinion. | during a recent study assessing the diversity of the species bacillus licheniformis, it became apparent that the type strain of bacillus aerius was not available from any established culture collection or from the authors who originally described it. other authors have reported similar findings when trying to obtain the strain (lai et al., 2014), therefore, this species cannot currently be included in any further scientific studies. it is proposed that, if suitable replacements for type strains ... | 2015 | 25908707 |
| evaluation of probiotic bacillus aerius b81e isolated from healthy hybrid catfish on growth, disease resistance and innate immunity of pla-mong pangasius bocourti. | infectious diseases have been found to be a major cause of mortality in fish hatcheries. probiotics have been introduced to replace antibiotics commonly used for treatment of bacterial infection in aquaculture. this study was conducted to isolate, screen, and evaluate the probiotic bacillus spp. for potential use as a feed supplement to enhance fish growth, disease resistance and innate immunity of pla-mong pangasius bocourti. bacillus aerius strain b81e was selectively isolated from the intesti ... | 2018 | 29162546 |
| comparative study of free and immobilized lipase from bacillus aerius and its application in synthesis of ethyl ferulate. | in the present study, a purified lipase from bacillus aerius immobilized on celite matrix was used for synthesis of ethyl ferulate. the celite-bound lipase exposed to glutaraldehyde showed 90.02% binding efficiency. it took two hours to bind maximally onto the support. the ph and temperature optima of the immobilized lipase were same as those of free enzyme i.e 9.5 and 55°c. among different substrates both free and immobilized lipase showed maximum affinity towards p-nitrophenyl palmitate (p-npp ... | 2014 | 25099909 |
| production and characterization of biodiesel using nonedible castor oil by immobilized lipase from bacillus aerius. | a novel thermotolerant lipase from bacillus aerius was immobilized on inexpensive silica gel matrix. the immobilized lipase was used for the synthesis of biodiesel using castor oil as a substrate in a solvent free system at 55°c under shaking in a chemical reactor. several crucial parameters affecting biodiesel yield such as incubation time, temperature, substrate molar ratio, and amount of lipase were optimized. under the optimized conditions, the highest biodiesel yield was up to 78.13%. the c ... | 2015 | 25874205 |
