    • Biosurfactants produced by microbes are used to control pests. The biosurfactants can be produced by cultivating a biosurfactant-producing microbe, producing a fermentation broth, and obtaining the biosurfactant from the fermentation broth. Alternately, the biosurfactants can be produced in situ in the environment of the pests by applying a carbon substrate to the pests' environment, which permits naturally-occurring biosurfactant-producing microbes to grow and to generate the biosurfactants. The biosurfactants have pesticidal qualities, and can be used to control a variety of pests, while being biodegradable and otherwise avoiding adverse environmental effects that have often been associated with conventional synthetic pesticides.
    • 由微生物生产的生物表面活性剂用于防治害虫。 生物表面活性剂可以通过培养生物表面活性剂生产微生物,产生发酵液,从发酵液中获得生物表面活性剂来生产。 或者,生物表面活性剂可以在害虫的环境中原位生成,通过将碳底物施加到害虫的环境中,这使天然存在的生物表面活性剂生成微生物生长并产生生物表面活性剂。 生物表面活性剂具有杀虫特性,可用于控制各种害虫,同时可生物降解,另外避免常规合成农药常常引起的不利环境影响。
