Myroides pelagicus sp. nov., isolated from seawater in Thailand

Abstract

An aerobic, Gram-negative, non-motile, yellow-to-orange pigmented and rod-shaped bacterium, designated strain SM1T, was isolated from seawater in Thailand and subjected to a polyphasic taxonomic study. Phylogenetic analyses based on 16S rRNA gene sequences revealed that the novel isolate shared 93–95 % sequence similarity with species of the genus Myroides. The DNA–DNA relatedness values of strain SM1T with Myroides odoratimimus JCM 7460T and Myroides odoratus JCM 7458T were below 70 %. The DNA G+C content of strain SM1T was 33.6 mol%, the major menaquinone was MK-6 and the major fatty acids were C15 : 0 iso, C17 : 1 ω9c iso and C17 : 0 iso 3-OH. Based on its phenotypic and chemotaxonomic characteristics, strain SM1T was classified as representing a novel species of the genus Myroides, for which the name Myroides pelagicus sp. nov. is proposed. The type strain is SM1T (=IAM 15337T=KCTC 12661T).
