A Gram-negative, rod-shaped bacterium (designated strain UST030701-295T) with fast gliding motility was isolated from the surface of the sponge Lissodendoryx isodictyalis in the Bahamas. Colonies of UST030701-295T were yellow in colour, 2-4 mm in diameter, convex with a smooth surface and entire margins. UST030701-295T was heterotrophic, strictly aerobic and required NaCl for growth (1.0-4.0%). Growth was observed at pH 6.0-10.0 and at 12-44 °C. Phylogenetic analysis of the 16S rRNA gene sequence placed UST030701-295T within the genus Winogradskyella of the family Flavobacteriaceae, sharing 94.7-95.8% similarity with the three recognized members of the genus. The G+C content of the DNA was 32.8 mol% and the predominant fatty acids were iso-C15:1, iso-C15:0, iso-C15:0 2-OH, iso-C15:0 3-OH, iso-C16:0 3-OH, C16:1ω7 and iso-C17:0 3-OH (together representing 75.4% of the total); these data supported the affiliation of UST030701-295T to the genus Winogradskyella. UST030701-295T differed from the three recognized species of Winogradskyella in 7-17 traits. Molecular evidence together with phenotypic characteristics suggests that UST030701-295T represents a novel species within the genus Winogradskyella, for which the name Winogradskyella poriferorum sp. nov. is proposed. The type strain is UST030701-295T (=NRRL B-41101T=JCM 12885T).
