We studied the deinking of recycled mixed oiffice paper (MOP) using two endo-glucanases. CalB and CelE. Treatment of MOP pulp with either enzyme followed by a flotation stage significantly reduced rior to those of CeIB. CelB was more effective than CelE at hydrolyzing pulp cellulose. Ink particles in MOP treated with CelB tended to be smaller than those treated with DelE. Ink particles smallen than 20 μm were not efficiently removed by flotation.
