摘要:

利用酸碱沉淀法分离提纯解淀粉芽孢杆菌JK-JS3分泌的杀线活性物质,获得具有杀线活性的水溶液,通过气质联用方法对其化合物的结构进行分析和鉴定,从该杀线组合物中共鉴定出3种化合物,分别为5-甲基-1-苯基-6H-1,3,5-三嗪-2-硫酮、2,2-二甲基-N-苯丙硫代酰胺和樟脑醛缩氨脲。对3种化合物在SciFinder数据库中进行专利和文献检索,未检索到上述化合物具有杀松材线虫活性的报道。

Abstract:

Bacillus amyloliquefaciens JK-JS3, isolated from the leaf of the Pinus massoniana in Dr.Sun Yat-sen's mausoleum, is a bacterium and has high nematicidal activity to a nematode(Bursaphelenchus xylophilus). A water solution with the nematicidal activity was isolated and purified from the bacterium culture medium by acid and alkali sedimentation method, and the components was analyzed by gas chromatography and mass spectrum. The result showed that the nematicidal activity components was composed of three compounds which included Hexahydro-5-methyl-1-phenyl-1,3,5-triazine-2-thione, 2,2-dimethyl-N-phenylpropanethioamide and Semiarbazide,4-(1,7,7-trimethylbicyclo hepty1-2-ideno)-.The three compounds have not been reported to have the nematicidal activity before based on a search of information and patents of the three chemical compounds in the SciFinder.

Key words: Bursaphelenchus xylophilus, Bacillus amyloliquefaciens, nematicidal active substance, structure analysis
