Abstract
A Gram-stain negative, aerobic, oxidase and catalase positive, non-flagellated, pink coloured bacterium with gliding motility, designated as strain UDD1T was isolated from soil. The bacterium lacked flexirubin-type pigments. Phylogenetic analysis based on its 16S rRNA gene sequence revealed that strain UDD1T formed a lineage within the family Cytophagaceae of the phylum Bacteroidetes, and forms a distinct clade with type strains of the closely related genus Pontibacter with similarities of 91.36-93.62%. Strain UDD1T contained MK-7 as the predominant menaquinone and summed feature 4 (iso-C17:1 I and/or anteiso-C17:1 B) and iso-C15:0 as the major fatty acids. The major polar lipids were phosphatidylethanolamine and an unidentified glycolipid. The DNA G+C content of strain UDD1T was 49mol%. On the basis of phenotypic, genotypic and phylogenetic analyses, the strain UDD1T represents a novel species of a new genus in the family Cytophagaceae, for which the name Edaphorhabdus rosea gen. nov., sp. nov., is proposed. The type strain of Edaphorhabdus rosea is UDD1T (= KCTC 62117T = JCM 32366T). The Digital Protologue Database Taxon number for strain UDD1T is GA00058.
