Interpretive Summary: This manuscript describes a new species of marine bacteria, Corynebacterium marinum, and a formal species description is reported in the manuscript. Bacteria from the marine environment possess novel or unusual biochemical characteristics that make them attractive for various agricultural or biotechnological purposes. As such, this strain was deposited into the ARS Culture Collection for future use.
A taxonomic study was performed on strain D7015T, which was isolated from coastal sediment close to a coal-fired power station in Qingdao, China. D7015T comprised Gram-positive, non-motile diphtheroid rods, which grew in 0-10 % (w/v) NaCl and 4-37°C, with optimum growth at 1% (w/v) NaCl and 30-32°C. The G+C content was 65.0 mol%. The major fatty acids were C18:1'9c (56.18%), C16:0 (38.02%), C16:1'7c (4.45%), C18:0 (1.0%) and C14:0 (0.35%). On the basis of the morphological, physiological and phylogenetic characteristics, D7015T was classified in the genus Corynebacterium. It exhibited a 16S rRNA gene sequence similarity of 95.9% and DNA:DNA relatedness value of 20.4% with C. halotolerans DSM 44683T. D7015T was sufficiently different from hitherto described Corynebacterium species to be considered as a novel species. The name Corynebacterium marinum sp. nov. is proposed with D7015T (= CGMCC 1.6998T = NRRL B-24779T) as the type strain.
