摘要: The potential of Parthenium sp. as a feedstock for enzymatic saccharification was investigated by using chemical and biological pretreatment methods. Mainly pretreatments (acid alkali) were compared with lignolytic fungi Marasmiellus palmivorus PK-27. Structural changes well crystallinity cellulose examined through scanning electron microscopy, fourier transform infra red X-ray diffraction analysis, respectively after pretreatment. Total reducing sugar released during pretreated substrates also evaluated. Among the methods, alkali (1 % NaOH) treated substrate showed high recovery acid perceptible polymerised lignin (7.53 ± 0.5 mg/g) significantly higher amount (513.1 ± 41.0 mg/gds) to uninoculated (163.4 ± 21.2) 48 h hydrolysis. This is first report enzyme production from M. palmivorus, prevalent in oil palm plantations Malaysia its application delignification Alkali treatment proves be suitable method enhanced yield which may used bioethanol
