Production of cellulose by CDB strains
Those isolates showing the ability to utilize cellulose were inoculated into MSM broth with different cellulose sources to determine cellulase activity. The result was observed at 560 nm and OD values were calculated spectrophotometrically. The result indicated that CDB 12 showed the highest level of cellulase activity followed by CDB 13 and CDB 21 in blotting paper. Overall, the result showed that cellulase enzyme activity was high in blotting paper when compared to the other two substrate sources tested (Table 2).
