Myroides marinus sp. nov., a member of the family Flavobacteriaceae, isolated from seawater.

A Gram-negative, aerobic, non-motile, yellow-pigmented, rod-shaped bacterium (strain JS-08(T)) isolated from seawater was subjected to a polyphasic taxonomic study. 16S rRNA gene sequence analysis indicated that strain JS-08(T) belongs to the genus Myroides, a member of the phylum Bacteroidetes. Its closest phylogenetic relative was Myroides odoratimimus JCM 7460(T), with which it shared 97.0 % 16S RNA gene sequence similarity. Strain JS-08(T) contained menaquinone-6 (MK-6) as the predominant menaquinone, and the dominant fatty acids were iso-C(15 : 0), iso-C(17 : 0) 3-OH and a summed feature consisting of iso-C(15 : 0) 2-OH and/or C(16 : 1)ω7c. The DNA G+C content of strain JS-08(T) was 34.2 mol%. Based on phenotypic, genotypic and phylogenetic evidence, it is suggested that strain JS-08(T) represents a novel species of the genus Myroides, for which the name Myroides marinus sp. nov. is proposed. The type strain is JS-08(T) ( = KCTC 23023(T)  = JCM 16529(T)).
