摘要 昆虫病原线虫共生细菌能够产生多种次生代谢产物,如抑菌物质、杀虫蛋白和胞外酶等。其中产生抗生素是共生细菌的普遍特征,并且其代谢产物对多种植物病原菌具有抑制作用,特别是对疫霉具有较好的拮抗作用。对共生细菌的有效抑菌成分进行分离提取,有助于发现新的抗生素。本文综述了昆虫病原线虫共生细菌对植物病原菌的抑制作用以及抑菌作用活性物质的种类、致病机理、产生条件等方面的研究进展。 A variety of secondary metabolites can be produced by the symbiotic bacteria of entomopathogenic nematode, such as antibacterial complex, insecticidal proteins and exo-enzymes, and so on. The production of antibiotics is common to symbiotic bacteria, and the metabolites of the symbiotic bacteria exhibit a broad spectrum of activity against a range of plant pathogenic fungi and bacteria, especially to the Phytophthora genus. New antibiotics can be found through purification and identify the active components of the symbiotic bacteria which have a strong antimi- crobial activity against the plant pathogens. This article was done to introduce the evolvement against the plant pathogens,the kinds, nosogenesis and producing conditions of the active antimicrobial substances produced by the symbionts of the entomopathogenic nematode.
