研究的动机吡嘧磺隆是农药“草克星”的化学名称。查询资料后我们发现,吡嘧磺隆是人工合成的化合物,在自然环境中较难分解,对多种敏感作物产生毒害作用。用什么方法能够解决吡嘧磺隆的毒害问题呢?我们想到微生物是自然界中生长、进化速度最快的类群,在吡嘧磺隆高浓度环境下(如农药厂排污口处),是否会有个别微生物进化出解毒能力呢?如果能够筛选到这种解毒微生物, Research Motivation Pyrimethazone is the chemical name for Pesticide “Grass Nemesis ”. After inquiring about the data, we found that pyrazosulfuron-ethyl is a synthetic compound that is harder to decompose in the natural environment and toxic to many sensitive crops. In what ways can we solve the problem of toxicity of pyrazosulfuron? We think of microorganisms as the most rapidly growing and evolving groups in nature. Whether pyrethrum pyroxen high concentration (such as the pesticide factory outlet) Individual microbes evolved detoxification ability? If you can screen to this detoxification microorganisms,
