PENGARUH KADAR LIGNIN TERHADAP PRODUKSI ENZIM SELULASE DARI TRICHODERMA VIRIDE MENGGUNAKAN SUBSTRAT ECENG GONDOK

Abstract

ABSTRACT

Pretreatment is done by removing the lignin (delignification) biomass conversion, thus increasing productivity of cellulase enzymes. In this study, the delignification was conducted by soaking for 24 hours  at room temperature using 5% ammonia solution, 0,1 N NaOH, 1,4% H₂SO₄ and also in physics. The result showed levels of lignin after-treament was 4,47% (ammonia), 9,27% (0,1 N NaOH), 10,24% (0,01 N H2SO4), 14,24% (without treatment).
