Influence of CBM source on cellulase activities. A. Kinetics studies on microcrystalline cellulose hydrolysis by the wild-type cellulases versus the chimaeric cellulases. B. Kinetics studies on microcrystalline cellulose hydrolysis by the combination of wild-type versus chimeric cellulases versus mixtures of wild-type and chimaeric enzymes. For convenience, keys and pictograms of the various enzymes are provided. For free enzymes combination, micromolar enzyme concentrations correspond to each one of the enzymes. Triplicates of each reaction were carried out, and standard deviations are indicated.
