A Gram-stain-positive, oxidase- and catalase-positive, aerobic, rod-shaped bacterium, designated strain SK-3146T, was isolated from animal feed. Phylogenetic analysis, based on 16S rRNA gene sequence comparisons, revealed that the strain formed a distinct lineage within the genus Paenibacillus that was closely related to Paenibacillusyunnanensis JCM 30953T (98.6 %), Paenibacillusvulneris CCUG 53270T (98.0 %) and Paenibacilluschinjuensis DSM 15045T (96.9 %). Cells were non-motile, endospore-forming and formed milky colonies on NA and R2A agar media. Growth of strain SK-3146T occurred at temperatures of 18-45 °C, at pH 6.0-9.5 and between 0.5-3.0 % NaCl (w/v). The major menaquinone was MK-7, with lesser amounts of MK-6 present. The cell wall peptidoglycan of strain SK-3146T contained meso-diaminopimelic acid. The major fatty acids were anteiso-C15 : 0 and iso-C16 : 0. The major polar lipids were diphosphatidylglycerol and phosphatidylethanolamine. The DNA G+C content was 53.8 mol% and the DNA-DNA hybridization relatedness values between strain SK-3146T and P.yunnanensis JCM 30953T and P.vulneris CCUG 53270T were 26.13±0.8 % and 38.7±0.6 %, respectively. The phenotypic, phylogenetic and chemotaxonomic results indicate that strain SK-3146T represents a novel species of the genus Paenibacillus, for which the name Paenibacillus konkukensis sp. nov. is proposed. The type strain is SK-3146T (=KACC 18876T=LMG 29568T).
