| phylogenetic analysis of culturable marine bacteria in sediments from the south korean yellow sea. | biogeochemical and microbiological characterization of marine sediments taken from the yellow sea of south korea was carried out. one hundred and thirty six bacterial strains were isolated, characterized and phylogenetic relationship was evaluated. the gene sequences of 16s rdna regions were examined to study the phylogenetic analysis of bacterial community in the marine sediments. among 136 isolates, 5 bacterial isolates were identified as novel members, remaining 131 isolates were fall into 5 ... | 2011 | 21675219 |
| oceanisphaera ostreae sp. nov., isolated from seawater of an oyster farm in the south sea, korea, and emended description of the genus oceanisphaera romanenko et al. 2003. | a gram-staining-negative, motile, non-spore-forming and short rod or rod-shaped bacterial strain, t-w6(t), was isolated from seawater of an oyster farm in the south sea, korea. strain t-w6(t) grew optimally at 25 °c and in the presence of 2 % (w/v) nacl. phylogenetic analyses based on 16s rrna gene sequences revealed that strain t-w6(t) joined the cluster comprising oceanisphaera species by a bootstrap resampling value of 90.8 %, and this cluster joined the clade comprising members of the genera ... | 2011 | 21257693 |
| oceanisphaera arctica sp. nov., isolated from a marine sediment of kongsfjorden, svalbard, arctic. | a novel gram-negative, coccoid shaped, non-motile bacterium, designated strain v1-41t, was isolated from a marine sediment sample collected at a depth of 200 m from kongsfjorden, svalbard, arctic. the cell suspension was brownish. cells of the strain v1-41t are positive for catalase, oxidase, lysine decarboxylase and ornithine decarboxylase and negative for gelatinase and lipase. cells of v1-41t hydrolyze esculin, starch and urea but not casein and dna. the fatty acids were dominated by saturate ... | 2010 | 20729309 |
| zobellella denitrificans gen. nov., sp. nov. and zobellella taiwanensis sp. nov., denitrifying bacteria capable of fermentative metabolism. | two denitrifying strains of heterotrophic, facultatively anaerobic bacteria, designated zd1(t) and zt1(t), were isolated from sediment samples collected from mangrove ecosystems in taiwan. the isolates were gram-negative. cells grown in broth cultures were straight rods that were motile by means of a single polar flagellum. the isolates grew optimally in 1-3 % nacl, but nacl was not an absolute requirement for growth; only strain zt1(t) grew in 13-14 % nacl. both isolates grew between 10 and 45 ... | 2006 | 16738093 |
| oceanisphaera donghaensis sp. nov., a halophilic bacterium from the east sea, korea. | a taxonomic study was carried out on two isolates, strains bl1(t) and bl11, from marine sediment collected from the east sea, korea. comparative 16s rrna gene sequence studies showed that these isolates clearly affiliated with the gammaproteobacteria. bl1t and bl11 were most closely related to oceanisphaera litoralis kmm 3654t (97.6 and 97.7 % 16s rrna gene sequence similarity, respectively). the level of 16s rrna gene sequence similarity between strains bl1t and bl11 was 99.7 %. the two isolate ... | 2006 | 16585712 |
| oceanimonas smirnovii sp. nov., a novel organism isolated from the black sea. | a slightly creamy, melanogenic, gram-negative, aerobic bacterium was isolated from seawater sample collected in the karadag natural reserve of the eastern crimea, the black sea. the novel organism was chemoorganotrophic, had no obligate requirement in nacl, tolerated to 12% nacl, grew between 10 and 45 degrees c, was slightly alkaliphilic, and was not able to degrade starch, gelatin, agar, and tween 80. 16s rrna gene sequence-based analyses of the new organism revealed that oceanimonas doudoroff ... | 2005 | 15830805 |
