Abstract
A Gram-negative, aerobic, motile and rod-shaped bacterium, designated strain T7-07 T, was isolated from compost in Daejeon, Korea. Phylogenetic analysis based on 16S rRNA gene sequencing showed that strain T7-07 T had 99.0% gene sequence similarity with Arenimonas malthae KACC 14618 T and 94.7-95.9% with other recognized species of the genus Arenimonas. Cells formed creamy white to yellowish colonies on R2A agar and contained Q-8 as the predominant ubiquinone, C 15: 0 iso, C 16: 0 iso, C 17: 1 iso ω9c and C 11: 0 iso 3-OH as the major fatty acids, and diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylmethylethanolamine and an unknown aminolipid as the major polar lipids. The DNA G+C content of strain T7-07 T was 68.3 mol%. DNA-DNA reassociation experiments between T7-07 T and Arenimonas malthae KACC 14618 T resulted in a mean relatedness value of 22.2 %. Combined genotypic and phenotypic data supported the conclusion that the strain T7-07 T represents a novel species, for which the name Arenimonas daejeonensis sp. nov. is proposed. The type strain is T7-07 T (=KCTC 12667 T=DSM 18060 T).
