Tellurirhabdus rosea gen. nov., sp. nov., a new member of the family Cytophagaceae isolated from soil in South Korea

Abstract

Strain U15(T), rod-shaped, catalase and oxidase positive, non-motile, hot pink pigmented, Gram-negative bacterium, was isolated from soil of Udo port, Udo Island, South Korea. Growth was observed at 10-48 degrees C, pH 6-11, and 0% (w/v) NaCl. Optimum growth conditions are 30-40 degrees C, pH 7-10, and 0% (w/v) NaCl. Phylogenetic analysis based on 16S rRNA sequences showed that strain U15(T) forms a distinct clade with type strains of the family Cytophagaceae, with similarities below 89%. The major polar lipids are phosphatidylethanolamine and phosphatidylserine. Strain U15(T) was found to contain MK-7 as the only menaquinone, and iso-C-15:0, C(16:1)5c, iso-C-17:0 3-OH and summed feature 3 (comprising C(16:1)7c and/or C(16:1)6c) as the major fatty acids (>10%). The DNA G+C content of strain U15(T) was determined to be 54.3mol%. Based on the phylogenetic, phenotypic characteristics and chemotaxonomic analysis data, strain U15(T) (=KCTC 62116(T)=JCM 32361(T)) should be classified as representing a novel species of a novel genus within the family Cytophagaceae for which the name Tellurirhabdus rosea gen. nov., sp. nov., is proposed.
