Corynebacterium marinum sp. nov. isolated from coastal sediment

A taxonomic study was performed on strain D7015T, which was isolated from coastal sediment close to a coal-fired power station in Qingdao, China. Strain D7015T comprised Gram-positive, non-motile diphtheroid rods, which grew in the presence of 0-8% (w/v) NaCl and at 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 C18:1ω9c (56.18%), C16:0 (38.02%), C16:1ω7c (4.45%), C18:0 (1.0%) and C14:0 (0.35%). On the basis of the morphological, physiological and phylogenetic characteristics, strain D7015T was classified in the genus Corynebacterium. It exhibited a 16S rRNA gene sequence similarity of 95.9% and a DNA:DNA relatedness value of 20.4% with Corynebacterium halotolerans DSM 44683T. Strain 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 strain D7015T (=CGMCC 1.6998T =NRRL B-24779T) as the type strain
