Bizionia sediminis sp nov., isolated from coastal sediment

A Gram-stain-negative, aerobic, non-gliding, rod-shaped and orange-coloured bacterium, designated strain P131(T), was isolated from marine sediment of the coast of Weihai, China, and subjected to a polyphasic study. Strain P131(T) was found to grow optimally at 28-30 degrees C, at pH 7.0-7.5 and in the presence of 2-3% (w/v) NaCl. In a phylogenetic analysis based on 16S rRNA gene sequences, strain P131(T) was found to belong to the genus Bizionia and exhibited 94.6-97.0% 16S rRNA gene sequence similarity with recognized Bizionia species. The dominant cellular fatty acids of strain P131(T) were identified as iso-C-15:0, iso-C-15:0 G, iso-C-17:0 3-OH and iso-C-17:1 omega 9c. The predominant polar lipids were phosphatidylethanolamine, phospholipid, two aminolipids and two unidentified lipids. The predominant respiratory quinone was menaquinone MK-6 and the DNA G+C content was 36.7 mol%. On the basis of the phylogenetic and phenotypic evidence presented, strain P131(T) represents a novel species of the genus Bizionia, for which the name Bizionia sediminis sp. nov. is proposed. The type strain is P131(T) (=KCTC 42587(T) =MCCC 1H00124(T)).
