Abstract

Strain 7SM30 an aerobic marine, Gram-negative, heterotrophic and yellow- to orange-pigmented bacterium isolated from seawater from Castellón, Spain, was characterized using a polyphasic approach. Analysis of the 16S rRNA gene sequence showed that the isolate represented a novel lineage within the family . The most closely related genera were , and . Cells of strain 7SM30 were non-motile rods that required sea salts for growth, used a wide variety of carbohydrates as sole carbon and energy sources and, unlike species of the genera and , did not possess flexirubin-type pigment or hydrolyse agar. Strain 7SM30 contained MK6 as the sole respiratory quinone. Phosphatidylethanolamine (PE) was the only identifiable polar lipid, although other lipids were also detected. The predominant cellular fatty acids were saturated C and monounsaturated C. The DNA G+C content was around 40 mol%. On the basis of extensive phenotypic and phylogenetic comparative analysis, it is concluded that the new strain represents a novel genus and species, for which the name gen. nov., sp. nov., is proposed. The type strain of the type species is 7SM30 (=CECT 7477=KCTC 22655).
