| Abstract: | In this paper,preliminary study on the laccase/mediator system(LMS) biobleaching of bagasse kraft pulp was carried out.Laccase was produced using a selected strain of Panus conchatus.Activity of laccase was measured with ABTS as substrate.A mediator —N-hydroxyacetanilide(NHA) was synthesized by reaction of hydroxybenzenamine with acetyl chloride.Laccase in the presence of NHA and oxygen was used for the bleaching of bagasse kraft pulp.It was found that the optimum conditions for the treatment of laccase/mediator system were:pH 5.0,temperature 50℃,reaction time 2 h,the charge of laccase 2.5U/g pulp,NHA 0.01g/g pulp and oxygen pressure 0.3 MPa respectively. |
