Abstract

A novel actinobacterium designated strain MSW19T was isolated from a seawater sample in Republic of Korea Cells were aerobic Grampositive nonendosporeforming and nonmotile cocci Colonies were circular convex opaque and vivid yellow in colour A phylogenetic tree based on 16S rRNA gene sequences exhibited that the organism formed a distinct clade within the radius encompassing representatives of the family Propionibacteriaceae The phylogenetic neighbors were the type strains of the genera Friedmanniella Microlunatus Micropruina Propionicicella and Propionicimonas Levels of 16S rRNA gene sequence similarity between the isolate and members of the family were less than 953 The cell wall peptidoglycan of the organism contained LLdiaminopimelic acid as the diagnostic diamino acid The isolate contained MK9H4 as the predominant menaquinone aiC150 as the major fatty acid and polar lipids including phosphatidylglycerol phosphatidylethanolamine and an unknown phospholipid The G+C content of the DNA was 696 mol On the basis of the phenotypic and phylogenetic data presented here the isolate is considered to represent a novel genus and species in the family Propionibacteriaceae for which the name Ponticoccus gilvus gen nov sp nov is proposed The type strain is strain MSW19T = KCTC 19476T= DSM 21351T
