Abstract
A Gram-negative, short-rod-shaped, orange-pigmented bacterium, strain LYYY01T, was isolated from a mangrove sediment sample collected from Yunxiao mangrove National Nature Reserve, Fujian Province, China. 16S rRNA gene sequence comparisons showed that strain LYYY01T is a member of the family Flavobacteriaceae , forming a distinct lineage with species of the genera Meridianimaribacter , Sediminibacter , Gelidibacter and Subsaximicrobium . The 16S rRNA gene sequence similarity between strain LYYY01T and the type strains of related species ranged from 93.9 to 90.9 %. Growth was observed at temperatures from 10 to 38 °C, at salinities from 1 to 7 % and at pH from 6 to 10. The DNA G+C content of the strain was 38.6 mol% and the major respiratory quinone was menaquinone-6 (MK-6). The major fatty acids were iso-C15 : 1 (27.6 %), iso-C15 : 0 (24.0 %), iso-C17 : 0 3-OH (12.0 %) and iso-C16 : 0 3-OH (6.2 %). According to its morphology, physiology, fatty acid composition and 16S rRNA gene sequence data, strain LYYY01T is considered to represent a novel species of a new genus in the family Flavobacteriaceae , for which the name Mangrovimonas yunxiaonensis gen. nov., sp. nov. is proposed. The type strain of Mangrovimonas yunxiaonensis is LYYY01T ( = CGMCC 1.12280T = LMG 27142T).
