Full-length and truncated forms of a modular thermostable xylanase (EC 22.214.171.124., glycoside hydrolase family 10) were used in bleaching sequences of hardwood and softwood kraft pulps. Enzymatic treatment led to brightness gains of all pulps but the result depended on the pulp source. The presence of the additional domains in the full-length enzyme (including carbohydrate-binding modules) did not improve the bleaching process. No significant change in viscosity was seen after enzyme treatments indicating an unaffected pulp fibre length.
