Flammeovirga pectinis sp. nov., isolated from the gut of the Korean scallop, Patinopecten yessoensis

Abstract

A novel Gram-stain-negative, aerobic, rod-shaped, reddish-orange-coloured, gliding bacterial strain, designated L12M1^T, was isolated from the gut of the Korean scallop, Patinopecten yessoensis. Phylogenetic analysis based on 16S rRNA gene sequence revealed that strain L12M1^T formed a monophyletic clade with the strains in the genus Flammeovirga and showed highest 16S rRNA gene sequence similarity to Flammeovirga kamogawensis YS10^T (98.66 %). The major cellular fatty acids of strain L12M1^T were iso-C_{15 : 0} and C_{20 : 4}ω6,9,12,15c. The predominant isoprenoid quinone was MK-7. The major polyamines were spermidine, cadaverine and the minor polyamine was putrescine. The DNA G+C content was 32.1 mol%. The phylogenetic, phenotypic, biochemical, chemotaxonomic and genotypic results indicated that strain L12M1^T represents a novel species of the genus Flammeovirga, for which the name Flammeovirga pectinis sp. nov. is proposed. The type strain is L12M1^T (=KCTC 62750^T=JCM 33169^T).
