Ortho-, meta-, and para-phenylenediamines were polymerized using hydrogen peroxide as an oxidant and horseradish peroxidase as a catalyst in mixed solvents of 1,4-dioxane and water. The yield of the polymers was strongly dependent on solvent composition, and maximum yields were obtained at 15-30% 1,

Enzymatic oxidative polymerization of p-alkylphenols using horseradish peroxidase as catalyst has been carried out in two polymerization solvent systems: a mixture of phosphate buffer (pH 7) and 1,4-dioxane, and a reverse micellar solution, yielding powdery polymeric materials. The polymer yield was
The potential of manganese peroxidase (MnP) from Phanerochaete chrysosporium to cross-link wheat arabinoxylans, and to covalently link cysteine and tyrosine to the ferulic acid esteriΓΌed on arabinoxylans, was investigated. MnP was able to gel arabinoxylans by oxidative coupling of their feruloyl gro
