纤维素酶与表面活性剂的相互作用及其在洗涤剂中的应用
Interaction of cellulase with surfactants and their application in detergent
摘要
Abstract
Effects of surfactants on cellulase activity were studied. The interaction mechanism between surfactants and cellulase was discussed by dynamic light scattering (DLS), fluorescence spectrum and ATR-FTIR. The DLS results showed that anionic surfactants were adsorbed onto cellulase surface, which made cellulase zeta potential distribute in the lower negative charge region. There was no obvious difference of cellulase zeta potential between in nonionic surfactants and deionized water. As shown in spectroscopy, the anionic surfactants had stronger influence on the main chain and side chain of cellulase than nonionic surfactant AEOs. The washing performance data of liquid detergent with and without cellulase indicated that adding cellulase into liquid detergent can enhance detergency of liquid detergent.关键词
