The enzymatic oxidation of lignin monomers via horseradish peroxidaseproduces small ogliomers that can have biological activity. These oxidation products were first investigated via 'beaker reactions,' where all substrates/enzyme were added to a single beaker. Reactions were then repeated using a flow-bioreactor containing immobilized enzyme. Product outcomes will be presented. Reaction products were analyzed using HPLC as well as other chromatographic methods. Additional results will be presented that discuss the stability/activity of the immobilized enzyme after repeated use.
