Abstract
For optimal cultivation of recombinant E. coli cells, it is necessary to monitor the intracellular enzyme activity by a fast, reliable and simple method. A modified air-segmented flow system is described for the on-line determination of intracellular penicillin-G-acylase (E.C. 3.5.1.11) during the cultivation of genetically modified E. coli 5K(pHM12). The results are compared to those obtained by different conventional off-line techniques.
