In: Journal of Agricultural Research Kafrelsheikh Univeristy 2008.v.34(4)Summary: Cellulose is the main constituent of higher plants, including rice straw and sugarcane bagasse. The chemical analysis showed that the cellulose content was 34.6 % and 42.186 % in rice straw and sugarcane bagasse respectively. The optimum conditions to obtain cellulose from rice straw, was 1.5 % NaOH concentration, 55°C, J: 15 and 150 minutes and in the: same-· conditions silica content reduced from7:2% to 4.5% and cellulose content was increased from 34.6 % to 38.73 %. On the other hand, the optimum conditions to produce cellulose from sugarcane bagasse was 2.5 % NaOH concentration, 70°C, J: 15 and 150 minute and in the same conditions sifica content reduced from 3% to 1.3% and cellulose content wasinereased from 42. J86 % to 44.98 %. The results showed .. that the optimum temperature and time on the cellulose isolation was J10°C and 10 minutes which gave 38.52% and 43.73% cellulose in rice straw and sugarcane bagasse respectively.
