| roseovarius nanhaiticus sp. nov., a member of the roseobacter clade isolated from marine sediment. | an aerobic, gram-staining-negative, rod or ovoid-shaped bacterial isolate, strain nh52j(t), was isolated from a sandy sediment sample from the south china sea. strain nh52j(t) exhibited tumbling motility, formed beige or faint pink colonies, gave a positive reaction in tests for catalase and oxidase and required nacl for growth. optimal growth was observed at ph 7.8-9.3, at 30 degrees c and in the presence of 2.0-4.0 % (w/v) nacl. the novel strain did not synthesize bacteriochlorophyll a, and th ... | 2010 | 19667376 |
| roseovarius indicus sp. nov., isolated from deep sea water of indian ocean. | a taxonomic study was carried out on strain b108t, which was isolated from a pahs-degrading consortium, enriched from the deep sea water of the indian ocean. the isolate was gram-negative, rod-shaped and non-mobile. growth was observed at salinities from 1 to 15 % and at temperatures from 10 to 39 °c, and it was unable to degrade tween 80 or gelatin. 16s rrna gene sequence comparisons showed that strain b108t was most closely related to rva. halotolerans lmg 24468t (97.1 %), followed by rva. pac ... | 2010 | 20851912 |
| nitropelagi marinus gen. nov., sp. nov., isolated from seawater, je-bu island, south korea. | a gram-stain-negative, non-spore forming, non-motile and aerobic strain, designated jb22(t), was isolated from seawater, je-bu island, south korea. strain jb22(t) was catalase and oxidase positive. optimal growth of jb22(t) was observed at 30 °c and ph 7.0. nacl tolerance range was 1-9 % (w/v) with an optimum of 2.0 % concentration. the phylogenetic analysis based on 16s rrna gene sequence of strain jb22(t) showed the highest sequence similarity to those of pelagicola litorisediminis d1-w8(t) (9 ... | 2016 | 27246498 |
| roseovarius scapharcae sp. nov., isolated from ark shell scapharca broughtonii. | a gram-stain-negative, non-motile, aerobic and ovoid or rod-shaped bacterium, designated ma4-5t, was isolated from ark shell (scapharca broughtonii) collected from the south sea, south korea. the novel strain grew optimally at 25 °c, at ph 7.0-8.0 and in the presence of 2.0 % (w/v) nacl. neighbour-joining and maximum-likelihood phylogenetic trees based on 16s rrna gene sequences showed that strain ma4-5t forms a coherent cluster with the type strains of roseovarius albus, roseovarius aestuarii a ... | 2015 | 26410220 |
| pontivivens insulae gen. nov., sp. nov., isolated from seawater. | a gram-stain-negative, aerobic, non-motile and coccoid, ovoid or rod-shaped bacterial strain, designated gysw-23(t), was isolated from seawater off geoje island in the south sea, south korea. strain gysw-23(t) grew optimally at 25 °c, at ph 7.0-8.0 and in the presence of approximately 2.0-3.0% (w/v) nacl. phylogenetic trees based on 16s rrna gene sequences revealed that strain gysw-23(t) forms a distinct evolutionary lineage independent of other taxa of the family rhodobacteraceae. it exhibited ... | 2015 | 26012580 |
| nioella nitratireducens gen. nov., sp. nov., a novel member of the family rhodobacteraceae isolated from azorean island. | a novel gram-negative, non-spore forming, rod-shaped aerobic bacterium, designated ssw136(t), was isolated from a surface seawater sample collected at espalamaca (in faial island), azores. growth was found to occur from 10 to 37 °c, ph 6.0-8.0, and with 2-11 % of nacl. 16s rrna gene sequence indicated that the strain ssw136(t) belongs to the family rhodobacteraceae. strain ssw136(t) exhibited 96.3, 95.9, 95.7 and 95.5 sequence similarity to the type strains oceanicola litoreus m-m22(t), roseovar ... | 2015 | 25500750 |
| roseovarius albus sp. nov., a new alphaproteobacterium isolated from the mediterranean sea. | strain 4sm10(t), an aerobic marine, gram-negative, heterotrophic and non pigmented bacterium isolated from seawater from vinaroz in castellón, spain, was characterized using a polyphasic approach. analysis of the 16s rrna gene sequence placed the strain within the roseobacter clade in the family rhodobacteraceae. phylogenetic analyses also showed that strain 4sm10(t) forms a stable clade with species of the genus roseovarius, being related to roseovarius nubinhibens ism(t) and roseovarius aestua ... | 2014 | 24488274 |
