摘    要:井冈霉素是最成功的生物源杀菌剂之一,也是防治水稻纹枯病的最常用与最有效的农药之一。文章综述了井冈霉素的理化性质及关于井冈霉素生物活性的研究,井冈霉素不仅抑制海藻糖酶活性,而且还具有抑制真菌的纤维素降解酶、多聚半乳糖醛酸酶和肌醇生物合成的活性;总结了井冈霉素的检测方法,通过色谱与质谱联用等方法来完成,最低检测量达到了0.4 ng。提出井冈霉素的生物合成是先将葡萄糖经过戊糖磷酸途径生成景天庚酮糖-7-磷酸,然后将葡萄糖与景天庚酮糖-7-磷酸经过10个酶催化,最终合成了井冈霉素A。最后评价了井冈霉素的发酵生产工艺,经过培养基组分优化、补料添加、发酵条件控制与分离工艺改进,井冈霉素的生产工艺也日趋完善。

Abstract:Jinggangmycin is one of the most successful bio-pesticides and is mainly used to protect Oryza sativa against Rhizoctonia solani. This paper reviewed the physicochemical property of jinggangmycin and the researches about the bioactivity of Jinggangmycin. jinggangmycin not only inhibited the activity of trehalase, cellulose-degrading enzymes and polygalacturonase but also affected the biosynthesis of inositol. Then the author summed up the detection method of Jinggangmycin. The lowest limit of jinggangmycin that could be detected was 0.4 ng with the LC-MS or GC-MS method. Then biosynthesis pathway of jinggangmycin was put forward, which was producing sedoheptulose-7-phosphate using glucose by pentose phosphate pathway and then catalyzing glucose and sedoheptulose-7-phosphate by 10 enzymes. The manufacturing technique of jinggangmycin has been greatly improved with the optimization of media components and feed-batch, the control of fermentation conditions and the separation process.
Keywords:jinggangmycin   validamycin   bio-pesticide   Streptomyces hygroscopicus   rice sheath blight
