| reclassification of marine agrobacterium species: proposals of stappia stellulata gen. nov., comb. nov., stappia aggregata sp. nov., nom. rev., ruegeria atlantica gen. nov., comb. nov., ruegeria gelatinovora comb. nov., ruegeria algicola comb. nov., and ahrensia kieliense gen. nov., sp. nov., nom. rev. | the bootstrapped 16s rdna sequence-based neighbor-joining phylogeny has suggested that the marine species of the genus agrobacterium have no relation to the terrestrial agrobacterium species. agrobacterium atlanticum iam 14463(t) (a superscript (t)=type strain), agrobacterium ferrugineum iam 12616(t), agrobacterium gelatinovorum iam 12617(t), agrobacterium meteori iam 14464(t), agrobacterium stellulatum iam 12621(t) and iam 12614, and the invalidly published marine species "agrobacterium kielien ... | 1998 | 12501429 |
| physiological, ecological, and phylogenetic characterization of stappia, a marine co-oxidizing bacterial genus. | bacteria play a major role in marine co cycling, yet very little is known about the microbes involved. thirteen co-oxidizing stappia isolates obtained from existing cultures, macroalgae, or surf samples representing geographically and ecologically diverse habitats were characterized using biochemical, physiological, and phylogenetic approaches. all isolates were aerobic chemoorganotrophs that oxidized co at elevated (1,000 ppm) and ambient-to-subambient concentrations (<0.3 ppm). all contained t ... | 2007 | 17142374 |
| [anoxygenic phototrophic bacterial community of lake shira (khakassia)]. | the anoxygenic phototrophic bacterial community of the brackish meromictic lake shira (khakassia) was investigated in august 2001, july 2002, and february-march 2003. in all the periods of investigation, the prevailing microorganisms were purple sulfur bacteria similar to lamprocystis purpurea in morphology and pigment composition. their highest number (3 x 10(5) cells/ml) was recorded in july 2002 at the depth of 15 m. according to 16s rrna gene analysis, the strain of purple sulfur bacteria is ... | 2007 | 17974211 |
| zhangella mobilis gen. nov., sp. nov., a new member of the family hyphomicrobiaceae isolated from coastal seawater. | a gram-negative, pale-yellow, non-spore-forming bacterium, motile with single polar flagella, strain e6t, was isolated from coastal seawater collected from tianjin, china, and its taxonomic position was investigated using a polyphasic approach. strain e6t requires nacl for growth and grows optimally at ph 8.2 and 36 degrees c and in the presence of 2.0% (w/v) nacl. it is positive for catalase and oxidase, and reduces nitrate to nitrite. the major fatty acids (>10%) are c18:1omega7c (64.71%) and ... | 2009 | 19620375 |
| Pseudahrensia aquimaris gen. nov., sp. nov., isolated from sea water of Yellow Sea in Korea. | A Gram-staining-negative, non-motile, ovoid to rod-shaped bacterial strain, designated HDW-32T, was isolated from seawater of the Yellow Sea, Korea. Strain HDW-32T grew optimally at pH 7.0-8.0, at 30 °C and in the presence of 2-3 % (w/v) NaCl. Strain HDW-32T exhibited highest 16S rRNA gene sequence similarity value (95.1 %) to Nitratireductor basaltis J3T, and sequence similarity values of 94.8 % to Ahrensia kielensis IAM 12618T and less than 94.2 % to other species used in the phylogenetic anal ... | 2011 | 22021581 |
