Strain W126(T), a Gram-reaction-positive, spore-forming, rod-shaped, facultatively anaerobic bacterium, motile by means of peritrichous flagella, was isolated from selenium mineral soil in Hubei province of China. 16S rRNA gene sequence analysis demonstrated that this isolate belonged to the genus Paenibacillus, with 97.9 % sequence similarity to Paenibacillus anaericanus MH21(T), while compared with the other species of the genus Paenibacillus, the 16S rRNA gene sequence similarities were less than 96.0%. DNA-DNA hybridization between strain W126(T) and Paenibacillus anaericanus DSM 15890(T) was 24%. The major isoprenoid menaquinone was menaquinone-7. Anteiso-C(15 : 0) was the major fatty acid. The DNA G+C content was 42.3 mol%. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, three unknown aminophospholipids and an unknown lipid. Strain W126(T) contained A1γ-meso-diaminopimelic acid in the cell-wall peptidoglycan. The phenotypic, chemotaxonomic and genotypic data indicate that strain W126(T) represents a novel species of the genus Paenibacillus, for which the name Paenibacillus selenii sp. nov. is proposed. The type strain is W126(T) ( = KCTC 33420(T) = CCTCC AB 2014003(T)).
