Abstract

The lignocellulosic materials, faba bean straw and green pea pods were chemically pretreated by sodium hydroxide or glacial acetic acid. The amount of cellulose residues from faba bean straw and green pea pods decreased gradually by increasing NaOH concentration under conditions of 3 ha 100°C and 48h. 25°C. While. pretreatment offaba bean straw with glacial acci Ic ac’id shoved higher yield of ccl litiose ( Sڑ()11 and 7(ijfl ) iu1c .. Ho s: i:.. above conditions. The chemical composition of faba straw and green pea pods were determined. Cellulose, hemicellulose and lignin contents were 32.3, 23.0 and 13.1% for crude faba bean straw and 29.22O4and10.6%forcrude green pea pods. After pretreatment, the extracted cellulose. hemicellulose and lignin contents were found to be (725, 10.5 and 7.2%) in faba bean straw and (80.0. 8. 1 and 4.8%) in pea pods, respectively. The rate of saccharification process were 62.2% by T. reesei, 59.9% by T. harzianum and 562% by A. niger for extracted cellulose of faba bean straw at concentration of 8% and the period of reaction was 6h. While. the saccharifi0cation rates were to 66.3. 58.8 and 65.0% by using the same above-mentioned fungi for extracted cellulose of green pea pods residue at concentration of 10% after 6 h. Production of ethanol by fermentation of the resultant glucose which produced frein saccharification processes amounted to 89.5;X4. ::iid S5. 7’ by using hydrolyzed carboxymethyl cellulose of T. reesei, I. nc2r:danunl ana A. niger, respectively. While, the ethanol produced from saccharification processes of faba bean straw and green pea pods estimated to (89.5, 89.5 and 88.5%) and (83.6, 89.5 and 88.0%) respectively by using produced cellulase from the aboveementioned fungi.
