| fulvimarina pelagi gen. nov., sp. nov., a marine bacterium that forms a deep evolutionary lineage of descent in the order "rhizobiales". | three brownish-yellow bacterial strains were isolated from the western sargasso sea by high-throughput culturing methods and characterized by polyphasic approaches. all isolates were gram-negative, strictly aerobic, chemoheterotrophic, non-motile short rods that contained carotenoid pigments. phylogenetic analyses based on 16s rrna gene sequences, dna-dna hybridization and dna g+c content, along with phenotypic characteristics, revealed that they belonged to the same species. the strains utilize ... | 2003 | 14657114 |
| martelella mediterranea gen. nov., sp. nov., a novel alpha-proteobacterium isolated from a subterranean saline lake. | a bacterial strain was isolated from the water of lake martel in mallorca (spain). the isolate, designated macl11(t), was halotolerant and strictly aerobic. the cells were non-motile, non-spore-forming, gram-negative short rods. comparative 16s rrna gene sequence analysis revealed that macl11(t) represents a separate line of descent within the order 'rhizobiales' of the class 'alphaproteobacteria'. strain macl11(t) was most closely related to the genera rhizobium (93.3 % sequence similarity to r ... | 2005 | 15774691 |
| aurantimonas ureilytica sp. nov., isolated from an air sample. | a novel strain, designated 5715s-12(t), was isolated from an air sample collected from suwon region, republic of korea, using r2a medium. the cells were strictly aerobic, gram-negative, motile, short rods. comparison of the 16s rrna gene sequence of strain 5715s-12(t) showed the highest sequence similarities to aurantimonas altamirensis s21b(t) (95.9 %) and aurantimonas coralicida wp1(t) (95.4 %). phylogenetic trees indicated that the strain formed a cluster with members of the family aurantimon ... | 2007 | 17684243 |
| molecular genetic analysis of a dimethylsulfoniopropionate lyase that liberates the climate-changing gas dimethylsulfide in several marine alpha-proteobacteria and rhodobacter sphaeroides. | the alpha-proteobacterium sulfitobacter ee-36 makes the gas dimethylsulfide (dms) from dimethylsulfoniopropionate (dmsp), an abundant antistress molecule made by many marine phytoplankton. we screened a cosmid library of sulfitobacter for clones that conferred to other bacteria the ability to make dms. one gene, termed dddl, was sufficient for this phenotype when cloned in pet21a and introduced into escherichia coli. close dddl homologues exist in the marine alpha-proteobacteria fulvimarina, lok ... | 2008 | 18237308 |
| genome sequence of fulvimarina pelagi htcc2506t, a mn(ii)-oxidizing alphaproteobacterium possessing an aerobic anoxygenic photosynthetic gene cluster and xanthorhodopsin. | fulvimarina pelagi is a mn(ii)-oxidizing marine heterotrophic bacterium in the order rhizobiales. here we announce the draft genome sequence of f. pelagi htcc2506(t), which was isolated from the sargasso sea by using dilution-to-extinction culturing. the genome sequence contained a xanthorhodopsin gene as well as a photosynthetic gene cluster, which suggests the coexistence of two different phototrophic mechanisms in a single microorganism. | 2010 | 20639329 |
| reclassification of aurantimonas altamirensis (jurado et al. 2006), aurantimonas ureilytica (weon et al. 2007) and aurantimonas frigidaquae (kim et al. 2008) as members of the genus aureimonas gen. nov., and emended descriptions of the genera aurantimonas and fulvimarina. | members of the genera aurantimonas and fulvimarina have been largely described on the basis of 16s rrna sequence, biochemical tests and limited chemotaxomic data. examination of the polar lipid compositions of members of these two genera indicate that although the patterns were similar with regards the phospholipid and amino lipid compositions, there were clear differences in the presence/absence of the glycolipid sulfoquinovosyldiacylglycerol (sqdg). this glycolipid was absent in aurantimonas c ... | 2010 | 21186293 |
