Avermectins are a series of 16 - membered macrocyclic lactones produced by streptomyces avermitilis with potent anthelmintic and insecticidal activity . they are the most effective agricultural pesticides and antiparasitic agents , and used widely in medical , veterinary and agricultural fields 阿維鏈霉菌( streptomycesavermitilis )產生的阿維菌素( avermectins )是一組高效、低毒、廣譜的殺蟲抗生素,在醫藥、農業和畜牧業生產中具有良好的應用價值和廣闊的市場前景。

In this paper , the important effect on the organisms life activities of plant essential oil as well as the terpenoids in it is described . it also introduces the researching progress of the plant essential oil in antiboisis , disinfection , mothkilling , anthelmintic action , insect killing , ovicidal action and its effect on the plants growth 論述了植物精油及其中所含的萜類化合物對生物的生命活動的重要作用.對植物精油在抗菌、殺菌、誘蟲、驅蟲、殺蟲、殺卵和影響植物生長等方面的研究進展進行了介紹

In addition to avermectins , s . avermitilis produces oligomycin , a strongly toxic compound . gene deletion vector pxl05 was used to disrupt oligomycin polyketide synthase ( pks ) encoding genes ( olma ) in streptomyces avermitilis cz8 - 73 , the producer of anthelmintic avermectins b and the cell growth inhibitor oligomycin . olma gene cluster in the chromosome was displaced by deletion allele on the plasmid via double crossover 本研究以產阿維菌素b和寡霉素的阿維鏈霉菌cz8 - 73為出發菌株,構建了基因缺失載體pxl05 ,并將其轉入cz8 - 73中,通過缺失載體和染色體之間的同源雙交換,對染色體上長達90kb的寡霉素聚酮合酶( pks )基因簇( olma )進行了缺失。
