Pulps were treated either with a purified single enzyme or the enzymes were successively added in different combinations. The residual pulps were delignified with alkaline peroxide and analysed for kappa number and ISO-brightness. 5 units and combination with lignin modifying enzymes improved the value by a further one unit. Lignin modifying enzymes when acting alone gave equal or even poorer pulp values than the reference.
