Phenanthrene was solubilized in two different nonionic surfactants, Tween80 and Triton X-100. The bioavailability of phenanthrene to the bacteria isolated from the petroleum contaminated soils was studied based on the rotary flasks experiments. The results showed that the concentration of nonionic surfactants above the critical micelle concentration (CMC) can increase the solubility of phenanthrene in water and were innoxious to the phenanthrene-degrading bacteria; phenanthrene solubilized in the micelles of Tween80 was bioavailable and biodegradable. The research demonstrated the potential of surfactant-enhanced bioremediation of soils contaminated by hydrophobic organic compounds (HOCs).
菲在两种不同的非离子表面活性剂吐温80和曲拉通X-100中溶解。基于摇瓶实验研究了菲对从石油污染土壤中分离出的细菌的生物可利用性。结果表明，高于临界胶束浓度（CMC）的非离子表面活性剂浓度可提高菲在水中的溶解度，且对菲降解细菌无毒害作用；溶解在吐温80胶束中的菲具有生物可利用性且可生物降解。该研究证明了表面活性剂强化修复疏水性有机化合物（HOCs）污染土壤的潜力。
