近年来,植物病害的生物防治越来越受到重视,生防细菌是在植物病害防治中应用最广、最有开发潜力的微生物。解淀粉芽孢杆菌(Bacillus amyloliquefaciens)是一种与枯草芽孢杆菌(Bacillus subtilis)亲缘性很高的细菌,不仅能够产生多种抗菌物质,如Iturin等环脂肽类物质,抑制植物病原菌生长,而且具有促进植物生长、诱导植物抗性的活性。因此,该菌被认为是继枯草芽孢杆菌后的又一生防菌,应用潜力巨大。然而, In recent years, biological control of plant diseases more and more attention, biocontrol bacteria is the most widely used in the prevention and treatment of plant diseases, the most development potential of microorganisms. Bacillus amyloliquefaciens is a kind of bacterium with high affinity with Bacillus subtilis. It can not only produce a variety of antibacterial substances such as Iturin and other cycloaliphatic peptides, inhibit the growth of plant pathogens, but also have Promote plant growth, and induce plant resistance activity. Therefore, the bacterium is considered to be a further bacterium after Bacillus subtilis, which has great potential for application. however,
