Abstract

A Gram-negative, motile and rod-shaped bacterial strain, designated ISL-43, was isolated from a marine solar saltern of the Yellow Sea, Korea, and its taxonomic position was investigated by means of a polyphasic study. Strain ISL-43 grew optimally at pH 7.0–8.0 and 30 °C and in the presence of approximately 2 % NaCl. It contained Q-8 as the predominant ubiquinone and C, C 8, C 7 and/or iso-C 2-OH, and C 7 as the major fatty acids. The DNA G+C content was 58.4 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain ISL-43 fell within the genus , clustering with M18 with a bootstrap value of 100 %. Strain ISL-43 exhibited 16S rRNA gene sequence similarity values of 98.1 and 95.5 % to M18 and M9, respectively. Strain ISL-43 exhibited DNA–DNA relatedness values of 17 and 10 % to KCTC 12357 and KCTC 12356, respectively. On the basis of phenotypic, phylogenetic and genetic data, strain ISL-43 represents a novel species within the genus , for which the name sp. nov. is proposed. The type strain is ISL-43 (=KCTC 22484=CCUG 56757).
