井冈霉素对3种生防芽孢杆菌的生长抑制活性

管碟法测定了井冈霉素对12株枯草芽孢杆菌（Bacillus subtilis）、6株苏云金芽孢杆菌（B．thuringiensis）及3株蜡质芽孢杆菌（Bacillus cereus）的离体抑制活性。结果表明，不同种以及同种不同菌株的芽孢杆菌对井冈霉素的敏感性存在差异，但从总体上看，井冈霉素A对大多数枯草芽孢杆菌的抑制作用较强．而对大多数蜡质芽孢杆菌和苏云金芽孢杆菌的抑制活性较低，在1．00×10^5mg／L浓度下仅有轻微的抑制作用。

Effects of Jinggangmycin on 3 Species of Bacillus

Antimicrobial effects of Jinggangmycin on 12 isolates of Bacillus subtilis, 6 isolates of B. thuringiensis, and 3 isolates of B. cereus were determined by cylinder-plate method in vitro. The results indicated that there were differences in the sensitivity of different species of Bacillus and different isolates of the same species to Jinggangmycin. As a whole, most isolates of B.subtilis were relatively sensitive to Jinggangmycin, while most isolates of B. thuringiensis and B.cereus were insensitive to it, o...
