Abstract

A Gram-reaction-positive, aerobic, rod-shaped, spore-forming bacterium, SK3146T, was isolated from complete feed in South Korea and characterized in order to determine its taxonomic position. On the basis of 16S rRNA gene sequence similarity, strain SK3146T was shown to belong to the family Paenibacillaceae, being related to Paenibacillus vulneris CCUG 53270T (98.1%) and Paenibacillus chinjuensis WN9T (96.9 %). The phylogenetic distances from other described species with validly published names within the genus Paenibacillus were greater than 3.3%. The G+C content of genomic DNA is 48.1±0.2 mol%. Phenotypic and chemotaxonomic data (major menaquinone, MK-7; fatty acid profile, anteiso-C15:0 and iso-C16:0) supported the affiliation of strain SK3146T to the genus Paenibacillus. The results of DNA-DNA hybridization test and physiological and biochemical tests allowed strain SK3146T to be distinguished genotypically and phenotypically from Paenibacillus species with validly published names. Strain SK3146T, therefore, represents a novel species of the genus Paenibacillus for which the name Paenibacillus konkukensis sp. nov., is proposed. Some biological activities of this strain should be characterized in future works, expecting for beneficial probiotics applicable to animal feed additive.
