<jats:title>Abstract</jats:title><jats:p>The adsorption of cellulases from <jats:italic>Trichoderma viride</jats:italic> was studied during the hydrolysis of newspaper. By measuring individual enzyme activities it was found that in the early stage of hydrolysis enzyme components showing C<jats:sub><jats:italic>x</jats:italic></jats:sub>A; were adsorbed preferentially to those showing C<jats:sub>1</jats:sub>A; afterwards ths situation was inverted. Electrophoretic resolution of proteins in hydrolysates showed a continuous decrease of enzyme proteins in solution, and furthermore suggested that the enzymes once adsorbed remained immobilized on the substrate (even after extensive digestion). Experiments to recover the enzyme that had remained in solution after typical hydrolysis showed a potential saving of up to 40%.</jats:p>
