Abstract

A Gram-stain-negative, rod-shaped, motile by gliding and yellow-pigmented bacterium, designated strain 10Alg 139, was isolated from the Pacific red alga . The phylogenetic analysis based on 16S rRNA gene sequences showed that the novel strain belonged to the genus , a member of the family , the phylum , with highest sequence similarity to KMM 3938 (99.3 %) and 93.3–98.6 % to other recognized species. The prevalent fatty acids of strain 10Alg 139 were iso-C 3-OH, C 3-OH, iso-C iso-C, C and Cω6. The polar lipid profile consisted of the major lipids phosphatidylethanolamine, two unidentified aminolipids and four unidentified lipids. The main respiratory quinone was menaquinone 6. The DNA G+C content of the type strain is 31.8 mol%. The new isolate and the type strains of recognized species of the genus were readily distinguished based on a number of phenotypic characteristics. A combination of the genotypic and phenotypic data showed that the isolate from alga represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is 10Alg 139 (=KCTC 52773=KMM 6729).
