模拟青霉素发酵过程中菌体生长动态的细胞自动机模型

A simulating biomass growth cellular automata model (CABGM for short) in penicillin batch fermentation process was constructed on the base of mechanism and dynamic differential equation model of penicillin batch fermentation process. CABGM adopts three-dimensional cellular automata as its growth space, adopts Morre type neighbourhood as its cell neighbourhood. The transition rules of CABGM were made based on mechanism and dynamic differential equation model of penicillin batch fermentation biomass growth process. Every cell of CABGM represents a single or specific number of penicillin production bacteria, and has various states. The results of statistic property theory analysis and simulation experiment show that CABGM replicated penicillin batch fermentation biomass growth process described by dynamic differential equation model accordantly. Finally, the application problem of CABGM in practical production processes is analyzed, and the future study problems are pointed out.
