Abstract

A milky-white-coloured, aerobic, Gram-stain-positive, rod-shaped and motile bacterial strain (GW78) was isolated from forest soil. GW78 was catalase-positive and oxidase-negative. The strain was able to grow optimally at 37 °C and at pH 7.0 in Reasoner's 2A media. The phylogenetic and 16S rRNA gene sequence analysis of GW78 showed its affiliation with the genus . The 16S rRNA gene sequence of GW78 revealed 98.3 % similarity to its nearest neighbour VKPM B-7519. Its chemotaxonomic properties included MK-7 as the sole menaquinone, phosphatidylglycerol, diphosphatidylglycerol, phosphatidylmonomethylethanolamine and phosphatidylethanolamine as major polar lipids, and anteiso-C, C 11 and anteiso-C as predominant fatty acids. Digital DNA–DNA hybridization and average nucleotide identity results with its closest relatives were <74.0 % and <14.0 %, respectively. Overall, 16S rRNA gene sequence comparisons, phylogenetic and genomic evidence, and phenotypic and chemotaxonomic data allow the differentiation of GW78 from other members of the genus . Thus, we propose that strain GW78 represents a novel species of the genus , with the name sp. nov. The type strain is GW78 (=KCTC 43430=NBRC 116023).
