ABSTRACT
Bioactive cellulose derivatives have been synthesised by coupling enzymes/antibiotics on carboxymethyl cellulose acid chloride and cellulose carbonate. The effect of pH and temperature on the enzymatic activity of amyloglucosidase immobilised on cellulose carbonate was studied. Michaelis-Menten kinetics have been obeyed to the first degree of approximation despite the restricted mobility of the attached enzyme on the polymer support. Lineweaver-Burk plots for the amyloglucosidase immobilized on carboxymethyl cellulose acid chloride at ambient pH with cellulose carbonate at pH 8 have also been plotted. The Michaelis-Menten constant for the immobilized amyloglucosidase on cellulose carbonate at pH 8 was 9.1 mM, and the activation energy for starch hydrolysis was 21.8 kcals/mole.
