摘要
为了更好地反映出青霉素发酵过程中菌体生长的复杂系统特征，在对青霉素生长分批发酵过程菌体生长机理研究基础上，建立了基于细胞自动机的青霉素分批发酵过程中菌体生长的可视化模型．模型采用二维彩色图案描述了青霉素菌体的生长演化过程；模型演化规则建立在青霉素生产分批发酵过程菌体生长机理及其动力学微分方程模型基础上，更加符合青霉素分批发酵过程菌体生长演化行为的多样性，随机性和不确定性的特点．仿真结果表明，该模型较好地描述了青霉素分批发酵过程中菌体生长的演化行为．
<abstract> order to reflect the complex system characterization of biomass growth in penicillin fermentation process, this paper established a biomass growth visual model of penicillin batch fermentation process based on cellular automata by studying the mechanism of penicillin batch fermentation process biomass growth. The model uses color parrern to describe the growth evolution process of penicillin biomass, and its evolution rules are designed based on penicillin batch fermentation process biomass growth mechanism and dynamics differential equations. The model conforms with special characteristics of diversity, random and uncertainty in penicillin batch fermentation process well. Simulation results show that the visual model described the evolution behavior of penicillin fermentation process biomass growth well.
