Abstract

A strictly aerobic, non-spore-forming, Gram-negative bacterium, designated strain HW7, was isolated from a rice field in Korea. Cells of strain HW7 were short rod-shaped and motile with single polar flagella. The major cellular fatty acids of strain HW7 were C and summed feature 3 (C 7 and/or iso-C 2-OH). The genomic DNA G+C content was 56 mol% and the major isoprenoid quinone was Q-8. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain HW7 forms a distinct lineage with respect to closely related genera within the class and that the levels of 16S rRNA gene sequence similarity with respect to the type species of related genera are less than 93 %. On the basis of the physiological and phylogenetic data, strain HW7 represents a novel genus and species of the , for which the name gen. nov., sp. nov. is proposed. The type strain is HW7 (=KCTC 12585=DSM 17879).
