Abstract	A thermoalkalophilic and cellulase-free xylanase produced from Arthrobacter sp. MTCC 5214 by solid-state fermentation using wheat bran as a carbon source was evaluated for prebleaching of kraft pulp. The UV absorption spectrum of the compounds released by enzyme treatment showed a characteristic peak at 280 nm, indicating the presence of lignin in the released colouring matter. Enzymatic prebleaching of kraft pulp showed 20% reduction in kappa number of the pulp without much change in viscosity. Enzymatic treatment reduced the amount of chlorine by 29% without any decrease in brightness. The viscosity of xylanase treated pulp was 4.0 p, whereas the viscosity of the pulp treated exclusively with chlorine was 4.1 p.
