Salegentibacter mishustinae sp. nov., isolated from the sea urchin Strongylocentrotus intermedius

Abstract

A bacterial strain, designated KMM 6049T, was isolated from the sea urchin Strongylocentrotus intermedius inhabiting the Sea of Japan. The bacterium studied was strictly aerobic, heterotrophic, yellow-pigmented, non-motile, Gram-negative and oxidase-, catalase-, β-galactosidase- and alkaline phosphatase-positive. 16S rRNA gene sequence analysis indicated that strain KMM 3524T was closely related to Salegentibacter holothuriorum and Salegentibacter salegens (sharing 97.7 and 98% sequence similarity, respectively). DNA-DNA relatedness levels between strains KMM 6049T and S. holothuriorum KMM 3524T and S. salegens DSM 5424T were 24 and 45%, respectively, indicating that KMM 6049T belongs to a novel species of the genus Salegentibacter, for which the name Salegentibacter mishustinae sp. nov. is proposed. The type strain is KMM 6049T (=KCTC 12263T=LMG 22584T=NBRC 100592T).
