| Popis: | An actinobacterial strain, designated ViU22T, was isolated from a natural uranium-rich soil and was studied using a polyphasic approach. Cells formed orange-pigmented colonies, were rod-shaped, Gram-positive (non-staining method), non-motile and non-spore-forming. This organism grew in 0–4.5 % (w/v) NaCl and at 15–37 °C, with optimal growth occurring in 0.5 % (w/v) NaCl and at 30 °C. Comparative 16S rRNA gene sequence analysis revealed that the strain ViU22T belonged to the genus Microbacterium . It exhibited highest 16S rRNA gene sequence similarity with the type strains of Microbacterium testaceum (98.14 %) and Microbacterium binotii (98.02 %). The DNA–DNA relatedness of strains ViU22T with the most closely related type strains Microbacterium testaceum and Microbacterium binotii DSM 19164T was 20.10 % (±0.70) and 28.05 % (±0.35), respectively. Strain ViU22T possessed a type B2β peptidoglycan with partial substitution of glutamic acid by 3-hydroxy glutamic acid. The major menaquinones were MK-11 and MK-12. Major polar lipids detected in the strain ViU22T were diphosphatidylglycerol, phosphatidylglycerol, an unknown phospholipid and unknown glycolipids. The predominant fatty acids were anteiso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0, a pattern reported for other Microbacterium species. The major cell-wall sugars were galactose, xylose and mannose and the DNA G+C content was 71 mol%. Together, the DNA–DNA hybridization results and the differentiating phenotypic characteristics, showed that strain ViU22T should be classified as the type strain of a novel species within the genus Microbacterium , for which the name Microbacterium lemovicicum sp. nov. is proposed. The type strain is ViU22T ( = ATCC BAA-2396T = CCUG 62198T = DSM 25044T). |
