Abstract

A taxonomic study was performed on strain D7015, which was isolated from coastal sediment close to a coal-fired power station in Qingdao, China. Cells of strain D7015 were Gram-positive, non-motile, diphtheroid rods that 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 DNA G+C content was 65.0 mol%. The major fatty acids were C 9 (56.18 %), C (38.02 %), C 7 (4.45 %), C (1.0 %) and C (0.35 %). On the basis of morphological, physiological and phylogenetic characteristics, strain D7015 was classified in the genus . It exhibited a 16S rRNA gene sequence similarity of 95.9 % and a DNA–DNA relatedness value of 20.4 % with DSM 44683. Strain D7015 was sufficiently different from recognized species of the genus to be considered to represent a novel species. The name sp. nov. is proposed, with strain D7015 (=CGMCC 1.6998=NRRL B-24779) as the type strain.
