Abstract:
:Among a group of marine isolates that were found to be positive for genes of the bacterial photosynthetic reaction centre, a strain was selected for characterization that was phylogenetically close to the genus Roseovarius. The strain, designated DFL-24T, originated from a culture of Alexandrium ostenfeldii (dinoflagellate) and contained small amounts of bacteriochlorophyll a, corresponding to about 1 % of the amount found in intensely pigmented aerobic phototrophs such as Roseobacter litoralis. Cells were rods of 0.5-0.7x1.3-3.0 microm often with uneven ends, suggesting a budding mode of division. True motility was not observed. Electron micrographs of ultrathin sections revealed a Gram-negative cell-wall structure. Cultures did not grow without addition of sea salts and tolerated up to 10 % (w/v) sea-water salts. Acetate, butyrate, tricarboxylic acid cycle intermediates, glutamate and glycerol were used as growth substrates, but not glucose or fructose. Biotin, thiamine and nicotinic acid were required as growth factors. The DNA G+C content was 63 mol%. 16S rRNA gene sequence analysis placed the strain within the Roseobacter lineage of the 'Alphaproteobacteria'. Its closest phylogenetic neighbour was Roseovarius tolerans showing 96.4 % 16S rRNA gene sequence similarity. Based also on its physiological and biochemical characteristics, the strain is considered to represent a novel species of the genus Roseovarius, Roseovarius mucosus sp. nov. Strain DFL-24T (=DSM 17069T=NCIMB 14077T) is the type strain. The 16S rRNA gene sequence of DFL-24T was found to have a similarity of 99.7 % with an unidentified strain, 253-13 (=DSM 17070), which was likewise characterized and shown to constitute another strain of the species.
