Brevibacterium anseongense sp. nov., isolated from soil of ginseng field

Gram-positive, aerobic, non-motile, pale-yellow, and rodshaped bacterium, designated as Gsoil 188^T, was isolated from the soil of a ginseng field in Pocheon, South Korea. A phylogenetic analysis based on 16S rRNA gene sequence comparison revealed that the strain formed a distinct lineage within the genus Brevibacterium and was most closely related to B. epidermidis NBRC 14811^T (98.4%), B. sediminis FXJ8.269^T (98.2%), B. avium NCFB 3055^T (98.1%), and B. oceani BBH7^T (98.1%), while it shared less than 98.1% identity with the other species of this genus. The DNA G + C content was 68.1 mol%. The predominant quinone was MK-8(H₂). The major fatty acids were anteiso-C_15:0 and anteiso-C_17:0. The cell wall peptidoglycan of strain Gsoil 188^T contained meso-diaminopimelic acid. The major polar lipids were phosphatidylglycerol, diphosphatidylglycerol, and an unidentified aminolipid. The physiological and biochemical characteristics, low DNA-DNA relatedness values, and taxonomic analysis allowed the differentiation of strain Gsoil 188^T from the other recognized species of the genus Brevibacterium. Therefore, strain Gsoil 188^T represents a novel species of the genus Brevibacterium, for which the name Brevibacterium anseongense sp. nov. is proposed, with the type strain Gsoil 188^T (= KACC 19439^T = LMG 30331^T).
