Abstract
A laser flow cytometer was used to study different Escherichia coli populations under various cultivation conditions. A host strain E. coli 5K was analyzed for cell size, protein and DNA-content during continuous cultivation. Also, a recombinant E. coli 5K(pHM12) strain (used for the intracellular production of penicillin-G acylase) was studied in regard to gene expression using different cytometric techniques. An argon ion laser (30 mW) and a 100 W high-pressure mercury lamp were used as light source in the cytometer. A new fluorogenic staining technique for intracellular penicillin-G acylase is described. Recombinant E. coli temperature sensitive cells were analyzed for intracellular fusion protein production due to temperature induction.
