Tumebacillus soli sp. nov., isolated from non-rhizosphere soil

A Gram-stain-positive, strictly aerobic, motile, spore-forming, rod-shaped bacterial strain, CAU 11108T, was isolated from soil in Danghangpo, Republic of Korea, and its taxonomic position was investigated using a polyphasic approach. The bacterium grew optimally at 37 °C, at pH 8, and in the presence of 1 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequence similarity revealed that strain CAU 11108T formed a distinct lineage within the genus Tumebacillus and was most closely related to Tumebacillus luteolus U13T (98.2 %). The strain contained menaquinone-7 (MK-7) as the major respiratory quinone and iso-C15 : 0 and anteiso-C15 : 0 as the major fatty acids. The DNA G+C content was 54.6 mol%. On the basis of phenotypic differentiation, phylogenetic and chemotaxonomic data, strain CAU 11108T represents a novel species of the genus Tumebacillus, for which the name Tumebacillus soli sp. nov. is proposed. The type strain is CAU 11108T (=KCTC 33141T=CECT 8918T).
