2.9. Effect of pH on the catalytic activity of free and immobilized enzyme
The influence of pH on the catalytic activity of free and immobilized maltase was investigated by performing the enzyme assay at different pH ranging from 5.0 to 8.0. Different buffers such as acetate buffer (pH: 5.0–6.0), citrate buffer (pH: 5.0–6.0) and potassium phosphate buffer (pH: 7.0–8.0) with same ionic strength (100.0 mM) were used.
