A white-colored bacterial strain designated J20-6ᵀwas isolated from peat soil collected in Russia. Based on the 16S rRNA gene sequence similarities, the strain J20-6ᵀbelonged to the genus Paenibacillus, and the closest relatives were Paenibacillus frigoriresistens YIM 016ᵀ(98.2 %), Paenibacillus alginolyticus DSM 5050Tᵀ(97.9 %), Paenibacillus chondroitinus DSM 5051ᵀ(97.4 %), Paenibacillus pocheonensis Gsoil 1138ᵀ(96.9 %), and Paenibacillus pectinilyticus RCB-08ᵀ(96.6 %). Cells are gram-positive, motile, facultative aerobic, endospore forming, and rod shaped. The cell wall contains MK-7 as the predominant menaquinone and meso-diaminopimelic acid as the diagnostic diamino acid. The major fatty acid is anteiso-C₁₅:₀, and the major polar lipids are diphosphatidylglycerol and phosphatidyl-ethanolamine. The DNA G+C content of the strain J20-6ᵀwas 49.9 mol %. The phenotypic, chemotaxonomic, and phylogenetic data clearly suggest that the strain J20-6ᵀbelongs to the novel member of the genus Paenibacillus, for which the name Paenibacillus alba sp. nov., is proposed. The type strain is J20-6ᵀ(=KEMC 7302-005ᵀ = JCM 18165ᵀ).
