Abstract

Abstract : A Gram-stain-negative, non-spore-forming, aerobic, motile, ovoid or short rod shaped bacterium, designed strain B17 T, was isolated from the culture broth of Picochlorum sp. 122. Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain B17 T forms a stable cluster with Oceanicolagranulosus MCCC 1A10589 T (with the highest 16S rRNA gene similarity of 95.8 %) and Roseisalinusantarcticus DSM 11466 T in the family Rhodobacteraceae . The only detected respiratory quinone was Q-10. The major cellular fatty acids were C18 : 1 ω7c/ω6 c, C17 : 1 iso I/anteiso B and C16 : 0 . The major polar lipids were phosphatidylglycerol, diphosphatidylglycerol, an unidentified phospholipid and two unidentified lipids. The genome G+C content was 69 mol%. Characteristics, such as a long lag phase, being motile with single polar flagellum, no aminolipid content, and little or no C18 : 1 ω7 c 11-methyl and C19 : 0 cyclo ω8 c content could significantly distinguish strain B17 T from its closely related type strains. Therefore strain B17 T is suggested to represent a new species in a new genus, for which Histidinibacterium lentulum gen. nov., sp. nov. is proposed. The type strain B17 T (=MCCC 1K03225 T =KCTC 52553 T ).
