| bacillus niabensis sp. nov., isolated from cotton-waste composts for mushroom cultivation. | a group of five bacilli, designated strains 4t12, 4t19(t), 5m45, 5m53 and 5t52, isolated from cotton-waste composts for mushroom cultivation, were examined. these strains were gram-positive, aerobic, motile, spore-forming rods. 16s rrna gene sequence analyses revealed that the isolates belonged to the genus bacillus, showing the highest levels of similarity (approx. 96.6-96.9 %) with respect to bacillus herbersteinensis dsm 16534(t). the values for dna-dna hybridization (approx. 85-96 %) among t ... | 2007 | 17684280 |
| isolation of heterotrophic bacteria from palk bay sediments showing heavy metal tolerance and antibiotic production. | analysis of culturable and unculturable bacteria and their potential bioactive compounds from palk bay is yet to be explored. the present study for the first time characterizes the culturable bacteria from palk bay sediment using 16s rrna gene sequencing. the characterized bacteria were also screened for antibacterial activity against human and aquaculture pathogens. in the 16s rrna gene sequence analysis characterized that most of the bacteria were affiliated to members of firmicutes and less w ... | 2010 | 20015629 |
| bacillus crassostreae sp. nov., isolated from an oyster (crassostrea hongkongensis). | a novel gram-stain-positive, motile, catalase- and oxidase-positive, endospore-forming, facultatively anaerobic rod, designated strain jsm 100118(t), was isolated from an oyster (crassostrea hongkongensis) collected from the tidal flat of naozhou island in the south china sea. strain jsm 100118(t) was able to grow with 0-13% (w/v) nacl (optimum 2-5%), at ph 5.5-10.0 (optimum ph 7.5) and at 5-50 °c (optimum 30-35 °c). the cell-wall peptidoglycan contained meso-diaminopimelic acid as the diagnosti ... | 2015 | 25713049 |
| bacillus halosaccharovorans sp. nov., a moderately halophilic bacterium from a hypersaline lake. | a novel gram-stain-positive, moderately halophilic bacterium, designated strain e33(t), was isolated from water of the hypersaline lake aran-bidgol in iran and characterized taxonomically using a polyphasic approach. cells of strain e33(t) were motile rods and produced ellipsoidal endospores at a central or subterminal position in swollen sporangia. strain e33(t) was a strictly aerobic bacterium, catalase- and oxidase-positive. the strain was able to grow at nacl concentrations of 0.5-25 % (w/v) ... | 2013 | 23291894 |
| bacillus cellulasensis sp. nov., isolated from marine sediment. | a novel bacterial strain nio-1130(t) was isolated from sediment sample taken from chorao island, goa province, india, and subjected to a taxonomic investigation. the strain was gram-positive, aerobic, and motile. phylogenetic analysis based on 16s rrna gene sequences placed the isolate within the genus bacillus and strain nio-1130(t) showed highest sequence similarity with bacillus halosaccharovorans dsm 25387(t) (98.4%) and bacillus niabensis cip 109816(t) (98.1%), whereas other bacillus specie ... | 2016 | 26410293 |
| bacillus endolithicus sp. nov., isolated from pebbles. | strain jc267t was isolated from pebbles collected from pingleshwar beach, gujarat, india. cells are gram-stain-positive, facultatively anaerobic, non-motile rods forming sub-terminal endospores in swollen ellipsoidal to oval sporangia. strain jc267t contains anteiso-c15 : 0, iso-c15 : 0, iso-c14 : 0, iso-c16 : 0, c16 : 0 and anteiso-c17 : 0 as major (>5 %) cellular fatty acids. polar lipids include phosphatidylglycerol, phospholipids (pl1-3), glycolipids (gl1-2) and an unidentified lipid. cell-w ... | 2015 | 26373875 |
| a heavy metal tolerant novel bacterium, bacillus malikii sp. nov., isolated from tannery effluent wastewater. | the taxonomic position of a gram-stain positive and heavy metal tolerant bacterium, designated strain nccp-662(t), was investigated by polyphasic characterisation. cells of strain nccp-662(t) were observed to be rod to filamentous shaped, motile and strictly aerobic, and to grow at 10-50 °c (optimum 30-37 °c) and at ph range of 6-10 (optimum ph 7-8). the strain was found to be able to tolerate 0-12 % nacl (w/v) and heavy metals (cr 1200 ppm, pb 1800 ppm and cu 1200 ppm) in tryptic soya agar medi ... | 2015 | 26362330 |
| effective microbial calcite precipitation by a new mutant and precipitating regulation of extracellular urease. | microbial calcite precipitation is a promising and environmental friendly biological technology in remediation of the surface and subsurface of porous media, especially for in situ soil remediation. the present study isolate a urea-degrading strain lh1 from soil on soybean root, identified as bacillus niabensis strain (99% similarity) by 16s rrna gene sequencing analysis. then, using ultraviolet mutagenesis method, a mutant lhum107 with outstanding urease-producing ability was further obtained t ... | 2014 | 24994684 |
