- 摘要:
- 采用硅胶柱层析的方法,对snef8菌株中的杀线虫活性物质进行了初步的分离,生物法测定各组份的杀线虫活性,减压浓缩有活性的组份制备粗提液。结果表明:菌液中的杀线虫活性物质主要集中于第8~第12号管中,其杀线虫活性接近于100%。此法不但可以除去部分杂质,提高粗提液的纯度,还可以应用制备型硅胶柱,大量制备富集粗提液,将其作为生物农药应用于农业生产,其防治根结线虫病效果较好。
- Abstract:
- The preliminary separation of the activity substances from the Fermentation against Meloidogyne incognitawas investigated by using silica gel column chromatography.The activity against Meloidogyne incognitaof each component was tested by vivo measurement.The crude extracts was prepared by decompressed and concentrated the activity component.The result showed that the activity substances against Meloiogyne incognita was in the bottles from No.8 to No.12.The methods could not only remove some impurities,improve the purity of the crude extracts,but also enrich lots of crude extracts by using the preparative silica gel column chromatography.This crude extracts could be used in agricultural production directly and the control effects was better.
