Catalyst potential of laccase-mediator systems
(1.10.3.2) which can reduce elemental oxygen to water in a four-electron step and simultaneously perform a one-electron oxidation of many aromatic substrates2. Due to the redox potential, laccase alone can only oxidize phenolic lignin structures. The addition of a mediator, a small chemical
