Biopulping from Banana Pseudo - Stem of Num-Wa by Trichoderma viride

Abstract

Study in the application of ligninolytic fungi for biopulping from banana pseudo-stem of Num-Wa was found that the incremental of T. viride had no effect to Kappa number and lignin degradation but depend on cultured time. The banana pseudo-stem of Num-Wa biopulping by T. viride with varied hydrogen peroxide bleaching (i.e. 0, 8, 10, 12, 14 and 16%) had kappa number lower than the product which was made from the chemical process. Paper produced from banana pseudo-stem of Num-Wa biopulping by T. viride used less hydrogen peroxide for bleaching than the chemical-made paper but yield more brightness in all level of hydrogen peroxide concentrations. Comparison the selective paper produced from T. viride bleaching with 12% hydrogen peroxide to the selective paper produced from chemistry bleaching with 14% hydrogen peroxide found that bursting strength had lower value by 3.3 and 3.9 kg/cm², respectively. However, tearing strength of paper produced from T. viride had higher than the paper produced from chemistry bleaching by 24.33 and 19.23 mN.m²/g, respectively.
