sp. nov., isolated from a brown algae reservoir Free

Abstract

A Gram-stain-negative, non-flagellated, rod-shaped bacterial strain able to move by gliding, designated WS-MY9, was isolated from a brown algae reservoir in South Korea. Strain WS-MY9 grew optimally at 25 °C, at pH 7.0–8.0 and in the presence of 2 % (w/v) NaCl. A neighbour-joining phylogenetic tree based on 16S rRNA gene sequences showed that strain WS-MY9 clustered with the type strain of with a bootstrap resampling value of 100 %. Strain WS-MY9 exhibited 16S rRNA gene sequence similarity values of 98.5 and 96.7 % to the type strains of and , respectively, and less than 96.1 % sequence similarity to other members of the family . Strain WS-MY9 contained MK-6 as the predominant menaquinone and anteiso-C, iso-C 3-OH, iso-C G and iso-C as the major fatty acids. The major polar lipids of strain WS-MY9 were phosphatidylethanolamine and two unidentified lipids. The DNA G+C content of strain WS-MY9 was 35.0 mol% and its DNA–DNA relatedness value with KCTC 12103 was 15 %. The phylogenetic and genetic distinctiveness and differential phenotypic properties revealed that strain WS-MY9 is separate from the two recognized species of the genus . On the basis of the data presented, strain WS-MY9 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is WS-MY9 ( = KCTC 32259 = CCUG 63684).
