Maribacter pelagius sp nov., isolated from seawater

A Gram-stain-negative, gliding, non-endospore-forming and slightly halophilic bacterial strain, CBA3204(T), was isolated from seawater and characterized by polyphasic taxonomic analysis. Phylogenetic analysis based on 16S rRNA sequences revealed that strain CBA3204(T) formed a distinct lineage within the family Flavobacteriaceae. The 16S rRNA sequences of strain CBA3204(T) had a sequence similarity level of 96.96% to Maribacter arcticus KOPRI 20941(T) as the nearest phylogenetic neighbour. The strain grew optimally at 25-30 degrees C and in the presence of 2-4% (w/v) NaCl. The dominant menaquinone was MK-6 and the major fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH and iso-C15 : 1 G. The DNA G+C content was 35.1 mol%. There were some differences in phenotypic properties among strain CBA3204T and other Maribacter species. On the basis of polyphasic analysis containing phenotypic, phylogenetic and chemotaxonomic data, strain CBA3204(T) (= KACC 17671(T) = JCM 19533T) is proposed as a novel species Maribacter pelagius sp. nov.
