An actinomycete strain, designated M1T8B9T, was isolated from cow dung in Suwon, Republic of Korea. The isolate was a Gram-positive, nonmotile, and non-spore-forming bacterium. Phylogenetic evaluation based on 16S rRNA gene sequence similarity showed that this isolate belongs to the genus Microbacterium, with its closest neighbors being Microbacterium soli DCY17T (98.2%) and Microbacterium esteraromaticum DSM 8609T (98.0%). The polar lipid pattern consisted of diphosphatidylglycerol, phosphatidylglycerol, and one unknown glycolipid. Strain M1T8B9T contained the major fatty acids C15:0 anteiso, C16:0 iso, C17:0 anteiso, and C15:0 iso, and the cell-wall peptidoglycan was of type B2β. According to DNA-DNA hybridization studies, strain M1T8B9T showed 42% and 26% relatedness with M. soli DCY17T and M. esteraromaticum DSM 8609T, respectively. On the basis of the data presented, strain M1T8B9T is considered to represent a novel species of the genus Microbacterium, for which the name Microbacterium suwonense sp. nov. is proposed. The type strain is M1T8B9T (=KACC 14058T =NBRC 106310T).
