Strain DY6ᵀ, a Gram-positive endospore-forming motile rod-shaped bacterium, was isolated from soil in South Korea and characterized to determine its taxonomic position. Phylogenetic analyses based on the 16S rRNA gene sequence of strain DY6ᵀ revealed that strain DY6ᵀ belongs to the genus Paenibacillus in the family Paenibacillaceae in the class Bacilli. The highest degree of sequence similarities of strain DY6ᵀ were found with Paenibacillus gansuensis B518ᵀ (97.9%), P. chitinolyticus IFO 15660ᵀ (95.3%), P. chinjuensis WN9T (94.7%), and P. rigui WPCB173ᵀ (94.7%). Chemotaxonomic data revealed that the predominant fatty acids were anteiso-C₁₅:₀ (38.7%) and C₁₆:₀ (18.0%). A complex polar lipid profile consisted of major amounts of diphosphatidylglycerol, phosphatidylethanolamine, and phosphatidylglycerol. The predominant respiratory quinone was MK-7. Based on these phylogenetic, chemotaxonomic, and phenotypic data, strain DY6ᵀ (=KCTC 33026ᵀ =JCM 18491ᵀ) should be classified as a type strain of a novel species, for which the name Paenibacillus swuensis sp. nov. is proposed.
