Abstract
Synthetic and natural zeolite were used to control the nitrogen source level in Bacillus megaterium cultures producing extracellular protein ase by means of reversible adsorption. The addition of biochemically i nert calcium aluminosilicates significantly increased the yield of the enzyme. A simple mathematical model explaining the mechanism has been formulated and its parameters estimated.
