碩士 === 國立中山大學 === 海洋環境及工程學系研究所 === 88 === In this research，we used three kinds of surfactant ，including Triton X-100(nonionic surfactant)，Triton QS-15 and SDS(anionic surfactant) ，to study the effects of PAHs degradation bacteria on phenanthrene. In addition， we also discussed the treatment effects of salicylate， which was functioned as an inducer，on degradation of phenanthrene by the microorganisms with and without the three surfactants. According to the experimental results，the conclusions were as following： 1. Biodegradation of PAHs was interfered by species surfactant，which was affected by the experimental factor，species of surfactant and bacteria. 2. In the low level of Triton X-100 system ，salicylate could enhance the degradation of phenanthrene. 3. The effect of degrading phenanthrene was obvious by adding salicylate to the system. 4. In the system containing Aluminum oxide and Triton QS-15， it could not enhance the degradation effects on phenanthrene. In the future study， we suggest to further discuss the enhancing effects of surfactant on bioremediation of PAHs.
