摘　　要：初步研究表明来自德国小蠊Blattella germanicaLinnaeus肠道的细菌能产生广谱的抗真菌活性物质,对白色念珠菌Candida albican、深红酵母Rhodotorula rubra(Demme)Lod-der、丝核菌Rhixoctoniasolani Huhn.、黄萎轮枝孢菌Verticillium alboatrumReinke、镰刀菌Fusarium solani(mart.)Sacc.、黄曲霉Aspergillus flavusLink、黑曲霉Aspergillus nigerVanTieghem都有明显的抑制作用。推测蜚蠊肠道细菌有助其抵抗病原真菌,同时也为开发用于医药、农业的广谱抗真菌的活性物质提供新途径。Cuhural suspension of bacteria, which isolated from Blattella germanica Linnaeus, has broad- rang antifungi activity. These active compounds can markedly inhibit the growth of Candida albican, Verticillum alboatrum, Fusarium sp., Rhodotorula rubra, Aspergillus niger, Aspergillus flavus, Rhizopus nigricans, Aspergillus ficuum, Rhixoctonia solaai, Trichoderma viride. It was presumed that the intestinal bacteria of cockroach can prevent the host from infection by pathogenic fungi. The active compounds produced by these intestinal bacteria have potential worth to develop new fungicide for medicine and agriculture
