Meridianimaribacter flavus gen. nov., sp. nov., a member of the family Flavobacteriaceae isolated from marine sediment of the South China Sea

Abstract

A Gram-staining-negative, rod-shaped marine bacterium, designated strain NH57NT, isolated from sandy sediment in the Mischief Reef of the South China Sea, was characterized based on its physiological and biochemical features, fatty acid profile and phylogenetic position. 16S rRNA gene sequence analysis revealed a clear affiliation with the family Flavobacteriaceae. Strain NH57NT showed the closest phylogenetic relationship with members of the genera Gaetbulibacter, Gelidibacter, Subsaxibacter, Subsaximicrobium and Yeosuana; levels of 16S rRNA gene sequence similarity between strain NH57NT and the type strains of related species ranged from 94.9 to 91.2 %. Cells of strain NH57NT were motile by gliding and grew on solid media as yellow colonies at 9–37 °C, pH 6.5–8.5 and in the presence of 0.5–4.0 % NaCl. The DNA G+C content was 32.7 mol% and the predominant fatty acids were iso-C15 : 1 (22.7 % of the total), iso-C15 : 0 (20.7 %), iso-C17 : 0 3-OH (9.5 %), iso-C16 : 0 3-OH (8.3 %), C15 : 0 (7.8 %) and iso-C15 : 0 3-OH (5.8 %). Based on the physiological and phylogenetic data, and on the fatty acid composition, strain NH57NT is considered to represent a novel species of a new genus in the family Flavobacteriaceae, for which the name Meridianimaribacter flavus gen. nov., sp. nov. is proposed. The type strain of Meridianimaribacter flavus is NH57NT (=CCTCC AB 208318T=LMG 24839T=MCCC 1A03544T).

Seonamhaeicola aphaedonensis gen. nov., sp. nov., a member of the family Flavobacteriaceae isolated from a tidal flat sediment

“…Comparative 16S rRNA gene sequence analysis indicated that the novel strain is phylogenetically most closely affiliated to the genera Meridianimaribacter and Mangrovimonas , members of the family Flavobacteriaceae . The genus Meridianimaribacter was proposed by Wang et al (2010) and at the time of writing comprises a single species with validly published name, Meridianimaribacter flavus . The genus Mangrovimonas was recently proposed by Li et al (2013) with the description of a single novel species, Mangrovimonas yunxiaonensis .…”
