Abstract

Two novel spore-forming bacteria with broad antimicrobial activity were isolated from roots of . The isolates, SD17 and SD18, were facultatively anaerobic and showed variable Gram reaction. Growth was observed between 20 and 45 °C. DNA G+C content of SD17 was 51·7 mol%, and the major fatty acid was anteiso-C (54·1 %). 16S rRNA gene sequence similarity of SD17 ranged from 98·6 to 91·3 % with other species. The phylogenetic tree showed that isolate SD17 formed a significant monophyletic clade with KCTC 2393 and IFO 15659. DNA–DNA relatedness values for strain SD17 with KCTC 2393 and IFO 15659 were 17·4 and 19·8 %, respectively. These isolates thus merit species status within , for which the name sp. nov. is proposed. The type strain is SD17 (=KCTC 10016BP=NBRC 100335).
