Summary The tyrosinases from Agaricus bisporus and Streptomyces eurythermus, laccases from Polyporus versicolor and Pleurotus ostreatus, and peroxidase from horseradish were strongly adsorbed on different bentonites and a clay-humus complex but less to on kaolinite and quartz. The adsorption was significantly dependent on the pH, reaching maxima in the range of the specific isoelectric points; it was less influenced by the valency and type of exchangeable cations. Most of the enzymes lost their activity when adsorbed on bentonite. The activity of desorbed enzymes was distinctly diminished when compared with free enzyme preparations. Conclusions from this behaviour were drawn as to the possible use of phenoloxidases as agents to transform phenolics in soil.
