title: Luteibaculum oceani gen. nov., sp. nov., a carotenoid-producing, lipolytic bacterium isolated from surface seawater, and emended description of the genus Owenweeksia Lau et al. 2005.
abstract: A yellow-pigmented, Gram-staining-negative, strictly aerobic, rod-shaped, non-flagellated, non-spore-forming, lipolytic and gliding marine bacterium designated strain CC-AMWY-103B(T) was isolated from surface seawater collected at Kending, Taiwan. The strain shared the highest 16S rRNA gene sequence similarity of 89.4% with Owenweeksia hongkongensis JCM 12287(T) and Brumimicrobium mesophilum YH207(T), and established a distinct phyletic lineage associated with the members of the family Cryomorphaceae. The polar lipid profile of strain CC-AMWY-103B(T) consisted of phosphatidylethanolamine, ten unidentified lipids and four unidentified aminolipids. The major fatty acids (>5% of the total) were iso-C15 : 0, iso-C15 : 1 G, C15 : 1ω5c, iso-C17 : 0 3-OH and C15 : 1ω8c. The DNA G+C content was 44.2 ± 0.3 mol%. The predominant respiratory quinone was menaquinone-6 (MK-6) and the major polyamine was spermidine. Based on its genetic, phylogenetic, phenotypic and chemotaxonomic distinctiveness, strain CC-AMWY-103B(T) is proposed to represent a distinct member of the family Cryomorphaceae, for which the name Luteibaculum oceani gen. nov., sp. nov. is proposed; the type strain of Luteibaculum oceani is CC-AMWY-103B(T) ( = JCM 18817(T) = BCRC 80551(T)). An emended description of the genus Owenweeksia is also proposed.
