Synthetic and natural zeolite were used to control the nitrogen source level inBacillus megaterium cultures producing extracellular proteinase by means of reversible adsorption. The addition of biochemically inert, calcium aluminosilicates significantly increased the yield of the enzyme. A simple ma...

Zusammenfassung:Synthetic and natural zeolite were used to control the nitrogen source level inBacillus megaterium cultures producing extracellular proteinase by means of reversible adsorption. The addition of biochemically inert, calcium aluminosilicates significantly increased the yield of the enzyme. A simple mathematical model explaining the mechanism has been formulated and its parameters estimated.[PUBLICATION ABSTRACT]
