title: Labedella gwakjiensis gen. nov., sp. nov., a novel actinomycete of the family Microbacteriaceae.
abstract: A Gram-positive, non-motile, non-mycelium-forming, rod-shaped actinomycete, designated KSW2-17T, was isolated from dried seaweed collected from beach sand along the coast of Jeju, Republic of Korea. The organism had ornithine as the diagnostic cell-wall diamino acid, MK-10 and MK-11 as the major menaquinones, and phosphatidylglycerol and diphosphatidylglycerol as polar lipids. The fatty acid profile included predominantly iso- and anteiso-branched acids and a minor amount of tuberculostearic acid (10-methyl C18:0). The DNA G+C content was 68.0 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that the seaweed isolate formed a distinct clade within the radiation of the family Microbacteriaceae and had highest sequence similarity (96.1-96.3%) to members of the genera Cryobacterium, Frigoribacterium and Rathayibacter. On the basis of phenotypic and genotypic evidence, strain KSW2-17T is considered to represent a novel species of a new genus, for which the name Labedella gwakjiensis gen. nov., sp. nov. is proposed. The type strain is KSW2-17T (=JCM 14008T=KCTC 19176T).
