Abstract
White-rot fungus Trameteshirsute (T.h. 19-6) was used for modifying the eucalyptus CTMP fibres. Results show that the T.h. 19-6 removed mainly lignin (by 7.42%) and extractive (by 11.52%) after a short period of 5days incubation. Due to the fungal degradation of the fibre wall materials, the middle lamella remainder on the fibre surface was significantly reduced and the fibre wall structure was loosened, which led to an increase in fibre internal bonding strength by 32% and an increase in handsheet tensile index and tear index by 49%, and 34%, respectively. A subsequent PFI refining process further amplified the fungal treatment effect, resulting in extensive fibre internal fibrillation. Compared with untreated pulp, fungus-treated pulp reached the same freeness levels with less PFI revolutions, indicating potential energy saving in the refining process.
