Spongiiferula fulva gen. nov., sp. nov., a Bacterium of the Family Flavobacteriaceae Isolated from a Marine Sponge

A Gram stain-negative, strictly aerobic, brown-pigmented, non-motile, rod-shaped, chemoheterotrophic bacterial strain-designated A6F-119T was isolated from a marine sponge (Rhabdastrella sp.). Phylogenetic analyses based on the 16S rRNA gene sequence revealed that the new strain represented a member of the family Flavobacteriaceae of the phylum Bacteroidetes and that it showed highest sequence similarity (93 %) to Tenacibaculum maritimum NBRC 15946T. The strain could be differentiated phenotypically from the recognized members of the family Flavobacteriaceae. The DNA G + C content of strain A6F-119T was determined to be 30.8 mol%; MK-6 was identified as the major menaquinone; and the presence of iso-C15:0, iso-C17:0 3-OH, and C16:1 ω7c and/or C16:1 ω6c as the major (>10 %) cellular fatty acids. A polar lipid profile was present consisting of phosphatidylethanolamine, an unidentified aminolipid, and three unidentified lipids. From the distinct phylogenetic position and combination of genotypic and phenotypic characteristics, the strain is considered to represent a novel genus for which the name Spongiiferula fulva gen. nov., sp. nov. is proposed. The type strain of S. fulva is A6F-119T (= KCTC 42752T = NBRC 111402T)
