芽孢杆菌(Bacillus)FJSC01对烟草土传病原菌的拮抗作用及其鉴定
Journal of Fujian Agriculture and Forestry University(Natural Science Edition)（2021）
Abstract
从番茄根际土壤分离到1株芽孢杆菌(Bacillus)FJSC01,其对烟草土传病原菌青枯拉尔氏菌(Ralstonia solanacearum)、胡萝 卜软腐果胶杆菌(Pectobacterium carotovorum)、尖镰孢菌(Fusarium oxysporum)、胶孢炭疽菌(Colletotrichum gloeospori-oides)、立枯丝核菌(Rhizoctonia solani)、疫霉菌(Phytophthora parasitica)和灰葡萄孢菌(Botrytis cinerea)等具有明显的拮抗作用.盆栽试验结果表明,菌株FJSC01对烟草青枯病的防效为40％.基于病原菌培养性状、形态特征、生理生化特性、16S rDNA系统演化分析,将菌株FJSC01鉴定为甲基营养型芽孢杆菌(Bacillus methylotrophicus).
