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

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’

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.
