Description Mesoporous alumina has been synthesized using egg shell membrane (ESM) as template. Aluminum
ion has been loaded on ESM by simple adsorption technique and then calcined to obtain the mesoporous
alumina. The characterizations of alumina loaded ESM (ESMAl) have been done by various techniques like
XRD, TEM, EDX and surface area. From immobilization studies the optimum pH and temperature for free
and immobilized CA were determined to be 7.5 and 25 ◦C, respectively. The Km and Vmax of immobilized
CA was found to be 5.3 mM and 1.753 �moles/ml/min by p-NPA assay. The storage stabilities for free
and immobilized CA were performed at 25 ◦C and it was found that the half life period for immobilized
CA has been improved by a factor 1.25 as compared to free CA. From leaching study the immobilized CA
could be reused up to 7th cycles. The carbonation capacity of immobilized CA was found to be 24.84 mg
of CaCO3/mg of enzyme as compared to 33.05 mg of CaCO3/mg of enzyme for free CA.
