A high-lignin-content softwood kraft pulp was reacted with laccase in the presence of 1-hydroxybenzotriazole (HBT), N-acetyl-N-phenylhydroxylamine (NHA), and violuric acid (VA). The biodelignification response with violuric acid was superior to both

The present study explores the efficiency of delignification achieved during standard oxygen, double-oxygen, and mini-oxygen [(E + O)Dkf=0.05(E + O)] delignification of high- (kappa = 56.2) and low- (kappa = 26.6) lignin-content softwood (SW) kraft p
