Abstract

The increase in pulp brightness and modification of pulp properties are some of the outcomes using xylanases in biobleaching. The effects produced on pulp could be evaluated and compared only in connection with the properties of the enzymes used. Therefore screening of various xylanases with novel properties and their testing on pulp are required in the process of selection of the optimal conditions for biobleaching. It appears that cellulase-free xylanase preparations of different microbial origin could reduce the xylan content of acid sulfite pulps. The bleachability of these pulps seems to improve in samples where xylan has been mostly affected enzymatically. However, the brightness gain obtained declines reversely to the increase in the number of chemical bleaching steps involved in the biobleaching.
