Abstract

Eco-efficient biotechnological applications are important innovations for modern industrial developments. Oxidoreductases, e.g. laccases and manganese peroxidases (MnPs), provide interesting possibilities. In many cases these enzymes require low molecular weight co-substrates to mediate oxidation. In this study, various types of lignin model compounds were investigated both as mediators and as final targets to find out their effect and potential in oxidation reactions, catalyzed by laccases and MnPs. Especially acetosyringone and methyl syringate mediated the laccase-catalyzed oxidation. These phenolics were also found to facilitate MnP-catalyzed reactions of non-phenolic compounds. Oxidation potentials, pH and chemical stability of the mediator affected the oxidation efficiency.
