摘　　要：在介绍细胞自动机基本概念、基本特征和仿真模型建立步骤的基础上,较详细地讨论细胞自动机在青霉素发酵过程菌体生长建模及仿真中的应用。在建立青霉素分批发酵过程菌体生长细胞自动机模型的前提下,以Matlab为开发工具实现了模型的可视化编程,并进行了仿真实验。实验结果表明,利用细胞自动机建立的青霉素分批发酵过程菌体生长仿真模型能较好地描述青霉素菌体生长的演化行为。由此可以看出,细胞自动机具有很强的模拟复杂物理现象或过程的能力,其为青霉素发酵过程的建模、仿真提供了一种理想的生命计算模型。On the basis of briefly introducing cellular automata (CA) basic concept, underlying property and simulation modeling steps using CA, the applications of CA in modeling and simulation of penicillin fermentation process biomass growth was studied. First, a penicillin batch fermentation process biomass growth simulation model based on CA was established, and then the program of this model was composed using Matlab. The simulation experiment results of the program show that the cellular automata simulation model well describes the evolution behavior of penicillin fermentation process biomass growth, the ability of cellular automata for simulating complex physical phenomenon or process is very powerful, and cellular automata are ideal artificial life calculation models for modeling and simulation of penicillin fermentation processes.
