Four of cellulolitic bacteria isolates had beencharacterized. The determination of cellulase activity was conducted at the highest production time, using crudeenzymes with the modification of Miller methods (1959) on pure cellulose substrates such as CMC (Carboxymethylcellulose), Avicel and Filter paper Whatman No. 1 as well as agriculture waste such as rice straw, corn cob and bananapeel. Cellulase from C4-4, C5-1, C5-3 and C11-1 showed optimum activity at pH 5, 70°C, pH 3.5, 90°C, pH 5, 80°Cand pH 8, 70°C, respectively. Avicel is a appropriate substrate for C4-4 cellulase whereas CMC for the other three.C11-1 cellulase has the highest cellulase enzyme activity...
