Canna edulis. Ker starch processing wastewater from craft villages contains high organic concentration such as starch, cellulose, xylan, protein… and especially high starch concentration after the states of grinding, sedimentation and filtration. The concentration of COD and BOD5, SS and coliform of wastewater are hundreds times higher than standards.

A carboxymethylcellulose (CMC)-degrading bacterium was isolated from soil, identified as Bacillus methylotrophicus according to the physiological properties and analyses of 16S rRNA and a partial sequence of the gyrase A (gyrA) gene, and named as B. methylotrophicus Y37. The CMCase enzyme was purified to homogeneity by 20.4-fold with 21.73% recovery using single-step hydrophobic interaction chromatography and biochemically characterized. CMCase showed a molecular weight of approximately 50 kDa as determined by SDS-PAGE.
