The Gram-stain-negative, rod-shaped bacterial strain designated RU-1-R-18(T) was isolated from intertidal sediment on Sakhalin Island in Russia. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain RU-1-R-18(T) was related to the genus Puniceibacterium and shared highest sequence similarities with the type strain Puniceibacterium antarcticum KACC 16875(T) (97.9%). The predominant cellular fatty acid was C-18:1 omega 7c. The polar lipid profile contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, one unidentified aminophospholipid and seven unidentified polar lipids. The genomic DNA G+C content of strain RU-1-R-18(T) was 59.1 mol%. Combined data from phenotypic, phylogenetic and DNA-DNA relatedness studies demonstrated that strain RU-1-R-18(T) represents a novel species of the genus Puniceibacterium, for which the name Puniceibacterium sediminis sp. nov. is proposed (type strain RU-1-R-18(T)=LMG 28384(T)=DSM 29052(T)).
