Hydrolytic enzymes effects on straw cellulosic pulp

Over 3,000 million tons of cereal straw is produced in the world per annum.(1) Among these amounts of renewable materials (particularly for production of chemical derivatives from cellulose, hemicellulose and lignin), the wheat straw is probably one of the most important as compared with other biomass resources. Its chemical modification to obtain cellulosic pulps by improving the efficiency of the already existing processes and the quality of the finished products should offer an attractive solution in the production of paper products and composite panels. In this study some properties of cellulosic pulp obtained by treatment with alkali (KOH) at a temperature of 900 C and bleached by chlorine free methods were investigated.
