Abstract

Cells of strain SW33, isolated from the seawater of Asan Bay, Republic of Korea, were characterized as Gram-stain-negative, aerobic, rod-shaped, motile and non-spore-forming. Phylogenetic analysis revealed that strain SW33 belonged to the genus and clustered distantly with the other genera in the family in the phylogenetic tree. The 16S rRNA sequences of strain SW33 revealed high similarities to SA4-48 (98.7 %), KDW4 (97.4 %) and PSC101 (97.3 %). The major fatty acids were C (27.9 %), summed feature 3 (32.2 %) and summed feature 8 (17.2 %). The predominant quinone was Q-8, and the polar lipid profile consisted of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and an unidentified amino lipid. The DNA G+C content was 38.3 mol%. The DNA–DNA relatedness values with the three species of KCTC 23240, KCTC 22500 and KCTC 32274 were 22, 23 and 18 %, respectively. Based on the phenotypic characteristics and taxonomic analyses, we propose that strain SW33 represents a novel species within the genus , for which the name sp. nov. with the type strain SW33 (=KCTC 52743=CICC 24249) is proposed.
