Balneola vulgaris
Description and significance
Balneola vulgaris is an aerobic, Gram-negative bacterium, named type strain 13IX/A01/164T. It was isolated from surface waters in the north-western Mediterranean Sea off the coast of France in the Bay of Baynuls-sur-Mer . Cells are motile, straight rods, 2.5 mm long and 0.2 mm wide. Balneola vulgaris forms orange colonies on marine agar medium.
Balneola vulgaris 13IX/A01/164T is an interesting addition to the family, Crenotrichaceae, because it does not exhibit the extremophilic qualities of other members. To date, most bacterium in the family Crenotrichaceae have been thermophilic or halophilic, favoring environments that high in heat or high in salt, respectively.
Phylogenetic Affiliation
The 16S rRNA gene was amplified and sequenced and the sequence was compared to those available in GenBank. Alignments and similarities showed that strain 13IX/A01/164T is phylogentically affiliated to the family Crenotrichaceae within the phylum Bacteroidetes. It is most closely related to Rhodothermus marinus NR-32T (16S rRNA gene sequence similarity of 87 %). Strain 13IX/A01/164T is also closely related to strains of Salinibacter ruber, Thermonema rossianum and Thermonema lapsum.
Cell Metabolism
13IX/A01/164T is an aerobic bacterium, requiring oxygen to oxidize substrates and generate energy. Metabolic test showed that Balneola vulgaris are able to use the following as carbon sources for energy: N-acetylgalactosamine, adonitol, arabinose, arabitol, erythritol, fructose, fucose, glucose, lactulose, maltose, methyl glucoside, sorbitol, acetate, hydroxyphenylacetate and propionate.
Ecology
Balneola vulgaris 13IX/A01/164T grows 10– 40 degrees C (optimum 30 degrees C), pH 5.0–10.0 (optimum pH 8.0), and a salinity range of 0–50 g l-1 (optimum 20 g l -1). These "normal" characteristics are unique; as indicated earlier, most members of the family Crenotrichaceae favor extreme environments.
Samples were collected in September 2001 in the bay of Banyuls-sur-Mer (42u 299 N 3u 089 E) by submerging a sterile bottle 0.5m deep and opening it to collect sea water. Balneola vulgaris 13IX/A01/164T was isolated from these water samples.
