Canonical biocontrol bacteria were considered to inhibit pathogenic bacteria mainly by secreting antibiotic metabolites or enzymes. Recent studies revealed that some biocontrol bacteria can inhibit pathogenic bacteria through contact-dependent killing (CDK) mediated by contact-dependent secretion systems. The CDK was independent of antibiotic metabolites and often ignored in normal biocontrol activity assay.

通过种间接触依赖性杀灭鉴定非典型拮抗细菌

传统的生物防治细菌被认为主要通过分泌抗生素代谢物或酶来抑制病原菌。最近的研究表明，一些生防细菌可以通过接触依赖性分泌系统介导的接触依赖性杀伤（CDK）来抑制病原菌。 CDK 独立于抗生素代谢物，并且在正常生物防治活性测定中经常被忽略。
