Two Gram-positive-staining, endospore-forming, rod-shaped, motile bacteria, strains DCY35T and C17, were isolated from soil of a ginseng field in South Korea and were characterized in order to determine their taxonomic positions. 16S rRNA gene sequence analysis revealed that the two strains belonged to the family Paenibacillaceae; strain DCY35T showed highest levels of similarity to strain C17 (99.9 %), Brevibacillus invocatus LMG 18962T (98.9 %), B. centrosporus DSM 8445T (98.0 %), B. borstelensis DSM 6347T (97.6 %), B. formosus DSM 9885T (97.4 %), B. agri DSM 6348T (97.3 %), B. brevis DSM 30T (97.3 %) and B. levickii LMG 22481T (97.0 %). Chemotaxonomic analyses revealed that strains DCY35T and C17 possess menaquinone MK-7, common to members of the genus Brevibacillus, and that the predominant fatty acids were iso-C15 : 0 (37.3 % of the total), anteiso-C15 : 0 (32.9 %), iso-C14 : 0 (11.8 %) and iso-C16 : 0 (6.5 %). The results of physiological and biochemical tests clearly demonstrated that strains DCY35T and C17 represent a distinct species. Based on these data, the two strains are considered to represent a novel species of the genus Brevibacillus, for which the name Brevibacillus panacihumi sp. nov. is proposed. The type strain is DCY35T (=KCTC 13206T =JCM 15085T).

The GenBank/EMBL/DDBJ accession numbers for the 16S rRNA gene sequences of strains DCY35T and C17 are EU383033 and EU383032, respectively.

A table giving levels of DNA–DNA relatedness among strains DCY35T and C17 and the type strains of eight closely related Brevibacillus species is available with the online version of this paper.
