Umboniibacter roseus sp nov., isolated from coastal seawater

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-B13(T) grew optimally at 30 degrees C, in the presence of 2 % (w/v) NaCl and at pH 7.5-8.0. Neighbour-joining, maximum-likelihood and maximum-parsimony 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)omega 7c and/or C-16 : (1)omega 6c) 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(T) is considered to represent a novel species of the genus, Umboniibacter for which the name Umboniibacter roseus sp. nov. is proposed. The type strain is 14-121-B13(T) (=DSM 29882(T)=KCTC 42467(T)).
