Abstract: Exponentially fed-batch cultures (EFBCs), fed with medium containing a highly concentrated carbon source, are commonly employed for attainment of high cell densities. However, large variations in environmental conditions occur, and quasi-steady-state is usually achieved only for the limiting substrate concentration, restricting the use of such cultures in kinetic characterization studies. In this work we report the production of recombinant penicillin acylase (PA) in EFBC of an E. coli JM101 transformed with t…
