The lignin peroxidase (LiP) biosynthesized from white rote species Aspergillus flavus SBC4-5 has been studied for high yield pulping from com stalks. Size reduced com stalks were treated by LiP with activity of 1.2 - 1.7 U/ml followed by the hydrogen peroxide pulping with adding acetic acid and TiO2 as catalyst. The results showed that the treatment of corn stalks by LiP in optimal conditions as follows: LiP dosage 10 U/g with the adding of 0, 1 mM H2O2/g of oven dried corn stalks (odw), solid to liquid ratio S:L=1:2, at 30°C and pH 3.0 for 5-6 hours improved delignification process and mechanical strengths of produced pulp. The mechanical properties of unbleached high yield pulp (breaking length:3892m
tear index: 3,66 mN.m2/g
burst index:1,38 kPa.m2/g) were improved by 7-14 percent compared to that of blank. This is a new direction on amicable technology for pulp production from crops.
