Bacterium Strain

A novel Gram-negative, obligately aerobic, non-motile, rod-shaped bacterium, strain M97T, was isolated from marine sediment of a cage-cultured ark clam farm on the south coast of Korea. Strain M97T was positive for oxidase and catalase. Optimal growth occurred at 37 °C, with 1–2 % (w/v) NaCl and at pH 7–8. The main cellular fatty acids were C16 : 0, C18 : 1ω7c, C12 : 0 3-OH and cyclo-C19 : 0ω8c. The polar lipids comprised diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, an unknown aminolipid and three unknown lipids. The predominant respiratory quinone was ubiquinone-10 (Q-10). Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain M97T belongs to the genus Tropicimonas , with highest sequence similarity to Tropicimonas aquimaris DPG-21T (99.0 %). The DNA G+C content of strain M97T was 68.5 mol%. Mean DNA–DNA relatedness between strain M97T and T. aquimaris DPG-21T was 46±10 %. Based on phylogenetic, phenotypic and genotypic analyses, strain M97T is considered to represent a novel species of the genus Tropicimonas , for which the name Tropicimonas sediminicola sp. nov. is proposed. The type strain is M97T ( = KACC 15544T = JCM 17731T).

A novel Gram-staining-negative, coccoid, non-motile bacterium, designated strain V1-41T, was isolated from a sample of marine sediment collected, at a depth of 200 m, from Kongsfjorden (an inlet on the west coast of Spitsbergen, an island that forms part of the Svalbard archipelago in the Arctic Ocean). The strain formed cream–brown colonies on marine agar. Cells of the novel strain were positive in tests for catalase, oxidase, lysine decarboxylase and ornithine decarboxylase activities but negative for gelatinase and lipase activities. They hydrolysed aesculin, starch and urea, but not casein or DNA. Most of the cellular fatty acids were medium-chain and saturated (37.1 %) or long-chain and unsaturated (27.8 %), with C12 : 0 (37.1 %), C18:1ω7c, and summed features 2 (19.3%) and 3 (24.1%) predominating. The major respiratory quinone was Q-8. The polar lipids consisted of phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, two unidentified aminophospholipids, four unidentified phospholipids and one other unidentified lipid. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the novel strain’s closest known relatives were Oceanisphaera litoralis DSM 15406T (98.5 % sequence similarity) and Oceanisphaera donghaensis BL1T (98.3 %). In DNA–DNA hybridizations, however, the levels of relatedness between strain V1-41T and O. litoralis DSM 15406T and between the novel strain and O. donghaensis DSM 17589T were found to be only 19 % and 29 %, respectively. Based on these low levels of similarity at the DNA–DNA level and the phenotypic and chemotaxonomic differences from O. litoralis DSM 15406T and O. donghaensis DSM 17589T, strain V1-41T represents a novel species of the genus Oceanisphaera for which the name Oceanisphaera arctica sp. nov. is proposed. The type strain is V1-41T ( = CCUG 58690T = KCTC 23013T = NBRC 106171T).
