Abstract
Growth parameters of
Pseudomonas aeruginosa were quantified based on steady-state concentrations, utilization rates of glucose and dissolved oxygen, and microorganism concentration in a chemostat that was operated at 25
°C, pH 7.2, and an agitation rate 350
rpm. The results showed that the microbial growth was limited by the concentration of glucose and the concentration of oxygen. A dual-substrate, Tessier growth kinetics for oxygen and glucose, was in good agreement with the experimental data using the following biokinetic parameters:
