Umboniibacter roseus sp. nov., isolated from coastal seawater

Abstract

A Gram-reaction-negative, non-motile, strictly aerobic, dark pink-pigmented and rod-shaped bacterial isolate, designated 14-121-B13 T , was isolated from surface seawater off the coast of the South Sea at Namhae-gun, Republic of Korea. Cells were catalase-and oxidase-positive and required NaCl for growth. Strain 14-121-B13T grew optimally at 30 8C, in the presence of 2 % (w/v) NaCl and at pH 7.5-8.0.Neighbour-joining, maximum-likelihood and maximumparsimony phylogenetic trees based on 16S rRNA gene sequences showed that strain 14-121-B13 T clustered with the type strain of Umboniibacter marinipuniceus, with which it exhibited 96.7 % sequence similarity. The DNA G+C content of strain 14-121-B13 T was 48.9 mol%. The major cellular fatty acids were summed feature 3 (C 16 : 1 v7c and/or C 16 : 1 v6c) and C 16 : 0 . The major respiratory quinone was ubiquinone Q-7 and the polar lipids detected in strain 14-121-B13 T were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, an unidentified aminolipid, unidentified phospholipids, unidentified aminophospholipids and unidentified lipids. Based on the phenotypic, chemotaxonomic and phylogenetic data presented, strain 14-121-B13
