Abstract:
Laccase is a ceruloplasmin widely used in industrial production. It is mainly used in catalytic degradation of lignin and its catalytic process is safe and environmental friendly. Small molecule medium is not only commonly used as a catalyst in the laccase catalytic reactions, but also can participate in the reaction as a substrate. In this study, the reactions of small molecules as substrates and laccase are investigated by the data of changes in the absorption wavelength of the reaction system recorded by ultraviolet spectrometer and analysis of the reaction of laccase and small molecules using MATLAB R2013a. It can be seen by the final results of hierarchical clustering analysis and calculation of the Euclidean distance that the entire medium system can be divided into three categories, namely, (i) Cumaric Acid, Sinapic Acid and HBT, (ii) Cumaric Acid and ABTS, and (iii) Ferulic Acid and Syringic Acid. The results of this study provide new ideas for finding and verifying potential medium systems.
