A Gram-stain-positive, aerobic, white-coloured, rod-shaped bacteria, designated as a strain dW9 T , was isolated from soil. Strain dW9 T was catalase-positive and oxidase-negative. Strain dW9 T grew at temperature of 20-37℃ and at pH of 5.0-7.0. Phylogenetic and 16S rRNA gene analysis indicated that strain dW9 T belonged to the genus Paenibacillus with its closest relative being Paenibacillus filicis S4 T (97.4% sequence similarity). The genome size of dW9 T was 7,787,916 bp with DNA G+C content of 51.3%. The digital DNA-DNA hybridization (dDDH) and average nucleotide identity (ANI) values of dW9 T with its closest relatives were found to be <22.0% and <74.0%, respectively. The only respiratory quinone was MK-7, and the major fatty acids were antiso-C 15:0 and iso-C 16:0 . Overall, the comprehensive taxonomic analysis revealed that strain dW9 T met all the fundamental criteria to be classified as a novel species within the genus Paenibacillus. Accordingly, we propose the name Paenibacillus gyeongsangnamensis sp. nov., with the type strain dW9 T (=KCTC 43431 T =NBRC 116022 T ).
