Resum

A novel method to monitor on-line intracellular β-galactosidase activity and biomass simultaneously, using flow injection analysis (FIA), has been developed. The automatic ultrasonic cell disruption and FIA analysis allow the processing of 10 samples/hour with a wide and variable linear working range of β-galactosidase activity and biomass and a maximum relative standard deviation (RSD) of 1.5%. The system has been optimized by monitoring biomass and intracellular β-galactosidase activity in Escherichia coli batch fermentation.
