Biomass immobilization technique has been put to practical use in advanced waste water treatment processes. The conventional immobilization technique, however, poses a problem with respect to mass transfer resistances for substrate and product molecules to the microorganisms inside immobilization gel matrices. The problem can be solved by utilization of functional gels as an immobilizing medium, which reversibly shrink and swell when external conditions change such as temperature, pH, solvent composition and so on. In this study, visible light-stimulus-response NIPA-CH(N-isopropylacrylamide-Chlorophyllin) gels were applied to examine a possibility of the utilization in waste water treatment processes. The purpose of this study was to investigate physical properties of the NIPA-CH gels such as swelling ratios, repetitive behaviour, and the influence of the immobilized microorganisms upon the swelling capacities. The NIPA-CH gels showed sufficient swelling ratios under cyclic visible light stimuli, and it was suggested that the mass transfer of substrates would be enhanced by the shrinking and swelling effects of the visible light-stimulus-response NIPA-CH gels.

生物质固定化技术已在污水深度处理工艺中得到了实际应用。然而，传统的固定化技术在底物和产物分子对固定化凝胶基质内微生物的传质阻力方面存在问题。利用功能凝胶作为固定介质可以解决这一问题。功能凝胶在温度、pH、溶剂成分等外界条件发生变化时，会发生可逆的收缩和膨胀。在本研究中，应用可见光刺激反应NIPA-CH（n -异丙基丙烯酰胺-叶绿素）凝胶来研究其在废水处理工艺中的应用可能性。本研究的目的是研究NIPA-CH凝胶的物理性质，如膨胀率，重复行为，以及固定化微生物对膨胀能力的影响。在可见光循环刺激下，NIPA-CH凝胶表现出足够的膨胀率，可见光刺激响应型NIPA-CH凝胶的收缩和膨胀效应可以增强底物的传质能力。
