| Abstract: | A strictly aerobic, gram-negative, non-motile, reddish-pink pigmented, rod-shaped strain designated N5EA6-3A2BT, was isolated from an unidentified marine sponge by use of a bait-streaked agar technique. Phylogenetic analyses based on
the 16S rRNA gene sequence revealed that the novel isolate represented a distinct and deep evolutionary lineage of descent
in the family Flammeovirgaceae within the phylum Bacteroidetes and clustered with as yet uncultured bacteria. The most closely related established species was Roseivirga spongicola UST030701-084T (89% sequence similarity) in the family of Flammeovirgaceae. The strain could be differentiated phenotypically and physiologically from recognized members of the family Flammeovirgaceae. The G+C content of DNA was 43 mol%, the major respiratory quinone was menaquinone 7 (MK-7) and iso-C15:0, C16:1ω5c and iso-C17:0
3-OH were the major fatty acids. From the distinct phylogenetic position and combination of genotypic and phenotypic characteristics,
the name Porifericola rhodea gen. nov., sp. nov. is proposed. The type strain of Porifericola
rhodea is N5EA6-3A2BT (=MBIC08357T = NBRC 107748T). |
