The inhibitory effect was strongest in King B2 medium, the optimum temperature for the highest antimicrobial activity was 33℃, and the optimal pH9.0. In the antagonistic test of BEB2 to the banana wilt disease, the inhibition was obvious with different in vitro methods, and the control effect of pot experiment was good.

结果发现，香蕉内生拮抗细菌BEB2为枯草芽孢杆菌；不同温度、pH值和培养基下的BEB2发酵液对香蕉枯萎病菌生长的抑制能力具显著差异，在King B2培养基上抑菌作用最强，最适抑菌温度为32 ℃，最适抑菌pH值为9.0。
