Abstract

Biopulping is the process of pretreating chips with fungus before mechanical pulping, resulting in significant energy savings and sheet strength improvements. This work presents sugar analysis, methylene blue adsorption, and titration data suggesting an increase in acid group content in wood is common with biopulping treatment. Some discussion of possible mechanisms of acid generation and fungal self-protection is presented.
