生物表面活性剂在环境生物工程中的应用

生物表面活性剂是由细菌，酵母或真菌生成的天然产物，由于其化学结构和物理性质相近或优于许多人工合成表面活性剂，并且对淡水，海水地球生态系统毒性较低，因而在环境污染的治理方面，特别是对石油和有机溶剂类污染现场的生物补救，具有极大的应用潜力。

Application of Biosurfactants in Environmental Biotechnology

Biosurfactants are natural products derived from bacteria,y6ast,or fungi.Due to their chemical structures and physical properities equal to,or exceeding,synthetic surfactants,and their low toxicity profile to freshwater,marine,and terrestrial ecosystems,biosurfactants are potential candidates for a variety Of environmental application,particularly for bioremediation of polluted materials,such as oil and organic solvent.The solubilization and emulsification of toxic pesticides by biosurfactants aid in degradation of such hazardous materials from contaminated site.The future success of biosurfactant technology in bioremediation will require the precise targeting of the biosurfactant system to the physical conditions and chemical nature of the pollution-affected site.
