Strain DCY16T, a Gram-positive, spore-forming, rod-shaped, motile bacterium, was isolated from soil and characterized in order to determine its taxonomic position. 16S rRNA gene sequence analysis revealed that strain DCY16T belonged to the genus Paenibacillus; highest sequence similarities were with Paenibacillus validus JCM 9077T (94.4 %), P. chinjuensis WN9T (94.4 %), P. naphthalenovorans DSM 14203T (94.2 %), P. ehimensis KCTC 3748T (92.8 %) and P. elgii KCTC 10016BPT (92.4 %). Chemotaxonomic data revealed that strain DCY16T possessed menaquinone MK-7 and the predominant fatty acids were C15 : 0 anteiso, C17 : 0 anteiso, C16 : 0 and C16 : 0 iso. The DNA G+C content of strain DCY16T was 50.9 mol%. Results of physiological and biochemical tests clearly demonstrated that strain DCY16T represents a distinct Paenibacillus species. Based on these data, DCY16T (=KCTC 13141T =JCM 14928T) should be classified as the type strain of a novel species, for which the name Paenibacillus ginsengihumi sp. nov. is proposed.
An extended phylogenetic tree based on 16S rRNA gene sequences showing the relationship between strain DCY16T and members of the genus Paenibacillus is available as supplementary material with the online version of this paper.
