- Abstract
A Gram-positive bacterium, designated M-GX18, was isolated from the rhizosphere soil of mango (Guangxi Province, China). The isolate produced nematicidal volatile compounds with activities against the root-knot nematode Meloidogyne incognita. The organism was motile, catalase- and oxidase-positive, spore-forming and rod shaped. The predominant menaquinone was MK-7 and the major cellular fatty acid profiles were iso-C, anteiso-C and iso-C. The DNA G+C content was 38.9%. A phylogenetic analysis based on 16S rRNA gene sequences showed that this organism represented a new species of the genus Lysinibacillus. Strain M-GX18 exhibited high 16S rRNA gene sequence similarity with its closest neighbors Lysinibacillus sphaericus (98.5%), Lysinibacillus fusiformis (98.1%) and Lysinibacillus xylanilyticus (98.6%). The physiological, biochemical and chemotaxonomic data, including DNA-DNA hybridization relatedness data, indicate that strain M-GX18 can be distinguished from all the related species of the genus Lysinibacillus. Therefore, on the basis of the polyphasic taxonomic data presented, a new species of the genus Lysinibacillus, Lysinibacillus mangiferahumi, with the type strain M-GX18 (=DSM 24076 = CCTCC AB 2010389) is proposed.
