Abstract

Controlled substrate addition was used to maintain mixed microbial cultures in fermenters at either pH 7.0 or 70% dissolved oxygen saturation. Control of pH permitted a greater volume of substrate to be processed. Ammonium nitrogen concentrations were similar for both fermenters but concentrations of oxidized nitrogen varied. Nitrification/denitrification sequences appeared to be initiated by unscheduled changes in dissolved oxygen concentration. It was possible to maintain a steady state with respect to a controlled parameter and end‐product quality but other parameters fluctuated.
