Abstract

Seven non-motile, facultatively anaerobic, alginolytic marine bacteria were isolated from the cultured clams and . Phylogenetic analysis based on 16S rRNA gene sequences showed that these marine bacteria were closely related to the recently described species , and (≥99.0 % sequence similarity). Phylogenetic analysis based on the housekeeping genes , and grouped the isolates together and allocated them to the species group. Amplified fragment length polymorphism DNA fingerprinting also grouped them together and enabled them to be differentiated from recognized species of the clade. DNA–DNA hybridizations showed that the isolates belonged to a novel species; phenotypic features such as the ability to grow at 4 °C and in the presence of 6 % NaCl also enabled them to be separated from other species. The DNA G+C content of RD 15.11 is 44.4 mol%. The genotypic and phenotypic data showed that the isolates represent a novel species in the clade. The name sp. nov. is proposed, with RD 15.11 (=CECT 7222 =LMG 23858) as the type strain.
