B006 辣椒疫霉病生防芽孢杆菌快速筛选及菌株的代 谢活性物质研究 摘要： 疫霉病是辣椒种植过程中严重威胁辣椒产量的一种病害，研究辣椒 疫霉病生防的筛选方法以及代谢活性物质对疫霉病的防治具有重要的意 义。本研究采用快速筛选法对从辣椒根际土壤中分离出的芽孢杆菌进行 B006 筛选，并对菌株的代谢活性物质进行研究。结果表明，通过快速筛 B006 Bacillus subtilisB006 选法，可有效筛选出芽孢杆菌，并鉴定其为。 对辣椒疫霉病具有一定的防治效果，其代谢产物具有较高的抗菌活性。 本研究为辣椒疫霉病的生防提供了一种有效的筛选方法，并为深入研究 芽孢杆菌的代谢活性物质提供了参考。 关键词：辣椒；疫霉病；芽孢杆菌；生防；代谢活性物质 Abstract ： Phytophthora blight is aserious disease that threatens the pepper production during its cultivation process. The study of screening methods for biological control of pepper phytophthora blight and the metabolites of bacteria against phytophthora blight has important significance. In this study, afast screening method was used to screen the spore rod bacteria isolated from pepper rhizosphere soil, and the metabolites of strain B006 were studied. The results showed that Bacillus subtilis B006 was effectively screened by afast screening method. B006 has acertain inhibitory effect on phytophthora blight, and its metabolites have high antibacterial activity. This study provides an effective screening method for biological control of pepper phytophthora blight, and provides areference for in-depth study of metabolites of spore rod bacteria.
