| halomonas neptunia sp. nov., halomonas sulfidaeris sp. nov., halomonas axialensis sp. nov. and halomonas hydrothermalis sp. nov.: halophilic bacteria isolated from deep-sea hydrothermal-vent environments. | to assess the physiological and phylogenetic diversity of culturable halophilic bacteria in deep-sea hydrothermal-vent environments, six isolates obtained from low-temperature hydrothermal fluids, sulfide rock and hydrothermal plumes in north and south pacific ocean vent fields located at 1530-2580 m depth were fully characterized. three strains were isolated on media that contained oligotrophic concentrations of organic carbon (0.002 % yeast extract). sequencing of the 16s rrna gene indicated t ... | 2004 | 15023967 |
| halomonas titanicae sp. nov., a halophilic bacterium isolated from the rms titanic. | a gram-negative, heterotrophic, aerobic, non-endospore-forming, peritrichously flagellated and motile bacterial strain, designated bh1(t), was isolated from samples of rusticles, which are formed in part by a consortium of micro-organisms, collected from the rms titanic wreck site. the strain grew optimally at 30-37°c, ph 7.0-7.5 and in the presence of 2-8 % (w/v) nacl. we carried out a polyphasic taxonomic study in order to characterize the strain in detail. phylogenetic analyses based on 16s r ... | 2010 | 20061494 |
| halomonas salicampi sp. nov., a halotolerant and alkalitolerant bacterium isolated from a saltern soil. | a gram-stain-negative, halotolerant and alkalitolerant bacterium, designated strain bh103t, was isolated from saltern soil in gomso, korea. cells of strain bh103t were strictly aerobic, motile, straight rods and grew at ph 7.0-10.8 (optimum, ph 8.5), at 10-55 °c (optimum, 28 °c) and at salinities of 0-23 % (w/v) nacl (optimum, 14 % nacl). phylogenetic analyses based on 16s rrna gene sequences indicated that strain bh103t belongs to the genus halomonas, showing highest sequence similarity to halo ... | 2015 | 26431725 |
| halomonas sulfidaeris-dominated microbial community inhabits a 1.8 km-deep subsurface cambrian sandstone reservoir. | a low-diversity microbial community, dominated by the γ-proteobacterium halomonas sulfidaeris, was detected in samples of warm saline formation porewater collected from the cambrian mt. simon sandstone in the illinois basin of the north american midcontinent (1.8 km/5872 ft burial depth, 50°c, ph 8, 181 bars pressure). these highly porous and permeable quartz arenite sandstones are directly analogous to reservoirs around the world targeted for large-scale hydrocarbon extraction, as well as subsu ... | 2014 | 24238218 |
| halomonas olivaria sp. nov., a moderately halophilic bacterium isolated from olive-processing effluents. | a moderately halophilic, gram-stain-negative, non-sporulating bacterium designed as strain tyrc17(t) was isolated from olive-processing effluents. the organism was a straight rod, motile by means of peritrichous flagella and able to respire both oxygen and nitrate. growth occurred with 0-25 % (w/v) nacl (optimum, 7 %), at ph 5-11 (optimum, ph 7.0) and at 4-50 °c (optimally at 35 °c). it accumulated poly-β-hydroxyalkanoate granules and produced exopolysaccharides. the predominant fatty acids were ... | 2014 | 24030688 |
