A marine bacterial strain, designated strain JUB59 T , was isolated from surface seawater in Antarctica and subsequently characterized. Cells were found to be Gram-negative, non-motile rods forming butyrous, shiny, yellowish orange colonies on marine agar. Growth occurred at 2–28 °C (optimally at 22–25 °C) but not at 30 °C; Na + ions were required, but 9 % NaCl (w/v) was not tolerated. Phylogenetic analysis, based on comparisons of the complete 16S rRNA gene sequence of the novel isolate with the sequences of closely related strains, showed that strain JUB59 T belonged to the family Flavobacteriaceae , representing a novel species of the genus Bizionia . The highest levels of sequence similarity were found with respect to Bizionia myxarmorum ADA-4 T (97.4 %) and Bizionia algoritergicola APA-1 T (97.1 %). However, the DNA–DNA relatedness of strain JUB59 T with respect to these two strains was low (15.9–17.3 and 19.3–22.1 %, respectively). The predominant fatty acids of strain JUB59 T were iso-15 : 1 10 c (18.1 %), iso-15 : 0 (17.3 %), anteiso-15 : 0 (13.9 %), iso-17 : 0 3-OH (9.2 %), 15 : 0 (6.0 %) and iso-16 : 0 3-OH (5.3 %). The main polar lipids were phosphatidylethanolamine, an aminolipid, an amino-positive phospholipid and two unidentified lipids. MK-6 was the major respiratory quinone (>90 %) and the DNA G+C content was 34 mol%. On the basis of the data obtained, strain JUB59 T represents a novel species of the genus Bizionia , for which the name Bizionia argentinensis sp. nov. is proposed. The type strain is JUB59 T (=DSM 19628 T =CCM-A-29 1259 T ).
The GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequence of strain JUB59 T is EU021217 .
A complete phylogenetic tree, details of the fatty acid and polar lipid compositions and micrographs of strain JUB59 T are available as supplementary material with the online version of this paper. |
