Abstract:
A Gram-negative, motile, rod-shaped marine bacterium, designated RKSG542 T , was isolated from the sea sponge Verongula gigantea collected at a depth of 20 m off the west coast of San Salvador, The Bahamas. Phylogenetic analyses based on 16S rRNA gene and genome sequences place RKSG542 T in a monophyletic clade with members of the genus Pseudovibrio . Strain RKSG542 T shared 〈 96.7 % 16S rRNA gene sequence similarity, 〈 72.2 % average nucleotide identity, 〈 66.7 % average amino acid identity, and 〈 24.8 % digital DNA–DNA hybridization with type strains of the family Stappiaceae . Growth occurred at 22–37 °C (22–30 °C optimum), at pH 7–9 (pH 7 optimum), and with 0.5–5 % (w/v) NaCl (2 % optimum). The predominant fatty acids ( 〉 10 %) were summed feature 8 (C 18 : 1 ω 6 c and/or C 18 : 1 ω 7 c ), C 18 : 0 and C 16 : 0 , and the respiratory lipoquinone was Q-10. The polar lipid composition comprised phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, three unknown aminolipids, six unknown phospholipids and four unknown lipids. The DNA G+C content of the genome sequence was 52.5 mol%. Based on the results of biochemical, phylogenetic and genomic analyses, RKSG542 T (=TSD-76 T =LMG 29867 T ) is presented here as the type strain of a novel species within the genus Pseudovibrio (family Stappiaceae , order Hyphomicrobiales , class Alphaproteobacteria ), for which the name Pseudovibrio flavus sp. nov. is proposed.
