Protein Soil Release Using Protease as Monitored with a Quartz Crystal Microbalance

摘要

Detergency is a complex procedure comprising both chemical and mechanical pro- cesses. In order to fully understand the chemical process, it is necessary to uncover its basic steps by setting up a simplified modeling system. In this study, we attempt to find the key to the detergency mechanism by revealing the adsorption of enzymes and surfactants onto proteins and the degradation and subsequent release of the proteins using a quartz crystal microbalance (QCM) measurement that can quantify minute weight changes in water over time.
