The investigation on the reaction of enzymatic oxidation of guaiacol as lignin model compound with hydrogen peroxide in the presence of horseradish peroxidase in water – DMSO binary solvents was done. Using the method of gas chromatography – mass spectrometry the five dimeric products of guaiacol oxidative coupling are identified. The possibility of the using of peroxidase in the mixtures of water with DMSO in the range of solvent compositions up to 30% (w/w) DMSO is shown. For the solvent compositions up to 30% vol. of DMSO the absence of the solvent effect on guaiacol oxidation products is stated.
