Abstract
Direct activity determination by a flow-through microcalorimetry in th e enzyme thermistor system was employed for a fast comparison of (poly )acrylamide gel-entrapped penicillin G acylase preparations. Compositi on of the pre-polymerization cocktail and both the storage and operati onal stabilities of optimal gel-entrapped enzyme preparations isolated from the Escherichia coli industrial strain were optimized by this me thod. The validity of the results was corroborated by spectrophotometr ic measurements.
