【摘要】 生物表面活性剂(Bio-surfactant)是由微生物产生的具有高表面活性的生物分子。由于其对生态系统无毒害作用,且可生物降解,因此,在提高原油产收率和环境污染治理等各方面得到了广泛应用。然而能否大幅度提高生物表面活性剂发酵产量是其能否实现商业化的一个首要问题。为此文章纵观了目前提高产量的研究重点,并对应用诱变育种和构建基因工程菌手段提高产量的发展前景作了展望。更多还原

【Abstract】 Biosurfactant as a high surface active agent synthesized by microorganism is widely used due to its low toxicity to environment. However, output of biosurfactant by fermentation is one of the key problems on how to make it into market. Means used in enhancing the production of biosurfactant are proposed and future development is prospected.更多还原
