Preliminary studies on the metabolic characteristics of thermophilic proteinase batch fermentation with FZ62 were carried out. The kinetic models for cell growth, enzyme production and substrate consumption were proposed basing on Logistic equation and Luedeking-piret eqution. Enzyme formation was growth-associated with cell growth in all batch cultures and the calculated results of models were compared satisfactorily with the experimental data.
