莲腐败病生防细菌3b培养条件的研究
Study of Medium and Cultural Conditions for Biocontrol Bacterial Strain 3b against Fusarium oxysporum f. sp. nelumbicola
摘要
Abstract
3b strain of bacteria was isolated after confrontation culture of bacteria and pathogens from the field soil infected by Fusarium oxysporum f. sp. nelumbicola. Antagonistic activity of strain 3b was evaluated under different culture conditions. The result showed that the strain could produce more antifungal substances under the optimum condition (culturing in PDB medium for 48 hours under 32℃and pH 7.0). Bacillus subtilis 3b is a bioagent with good effect of controlling rhizome rot of lotus. All results indicated that the best control effect on rhizome rot of lotus was made by directly using microorganism agents. These studies implied that there might be a promise to control the disease effectively with bioagents.关键词
