| 中文摘要 |
| 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、海水及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。此外,生物表面活性剂对有毒杀虫剂的增溶与乳化作用也有助于在污染场地降解这些有害物质。今后,生物表面活性剂技术要成功地应用于生物补救处理,需重点研究和开发与污染场地的物理条件和化学性质极其适应的生物表面活性剂系统。 |
| 英文摘要 |
| Biosurfactants are natural products derived from bacteria,yeast,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. |
