摘要：
We studied the deinking of recycled mixed office paper (MOP) using two endo-glucanases, CelB and CelE. Treatment of MOP pulp with either enzyme followed by a floatation stage significantly reduced both dirt count and residual ink area and increased brightness. CelE appeared to have deinking effects superior to those of CelB. 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 CelE. Ink particles smaller than 20 mum were not efficiently removed by flotation.
