Fed-batch cultivation of gene-engineered E. coli was conducted using 1.4 dm3 scale fermenter, where plasmid pRZ, which contained A-phage PR promoter and lacZ structure gene, was used to transform the Escherichia coli N 4830-1. Two stage cultivation method was employed, where temperature and pH were controlled at 30°C and 7.0, respectively, during the initial 8 hours to enhance the cell growth. After 8 hours, the culture temperature was raised to 37-42°C to induce gene expression, where pH was also changed for the efficient production of gene product (β-galactosidase).<BR>Based on the results obtained from several fed-batch runs of cultivations, an unstructure model was developed to derive the optimal temperature and pH patterns using a Genetic Algorithm. Experiments were conducted based on the derived temperature and pH patterns, and it was verified that the productivity of gene product was the highest among the past experiments.
