Abstract

A Gram-reaction-negative, rod-shaped, facultatively anaerobic, motile bacterium, designated strain AR1, was isolated from a freshwater stream in Jeonju, South Korea. Strain AR1 showed highest 16S rRNA gene sequence similarity (96.83 %) and also formed a separate clade with GPTSA-6 in the phylogenetic tree reconstructed among the members of the family . Major cellular fatty acids are summed feature 3 (Cω7/Cω6) and C. Diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylglycerol are the predominant polar lipids. The genomic DNA G+C content was found to be 54.7 mol%. However, earlier studies on 16S rRNA gene, , and universal target region of sequences of the members of the genus recommended the transfer of to a new genus. Hence, based on the comparative polyphasic data obtained during the present study and also on the previous recommendations, it is proposed that be transferred to a novel genus as gen. nov., comb. nov. with strain GPTSA-6 (=DSM 17445=MTCC 7090=CIP 109378=CCUG 54939) as the type strain of the type species of the genus. Also, it is proposed that strain AR1 be designated as a representative of a novel species of this new genus, namely sp. nov. The type strain is AR1 (=KCTC 42754=JCM 31503).
