Application of biological system to pulping and bleaching process

Abstract

Recent advances in the knowledge of ligninolytic enzyme system and recent trial to apply biological system to pulping and bleaching process are reviewed. Although a remarkable progress in the enzymology of lignin biodegradation was achieved in these ten years, the application of ligninolytic system to pulping and bleaching is not very successuful. Enzymatic degradation of carbohydrate, on the other hand, has been found to be useful for bleaching and fiber modification.
