Cell growth, PHB production, and carbohydrate uptake by H. boliviensis as a function of production time in an ALR operated in a batch system. Air flow rate into the reactor was set at 2.0 L min⁻¹, pH was maintained at 7.5 ± 0.3 and water at 35 °C was circulated by the jacket of the reactor. The initial MSG concentration was 2 g L⁻¹. The experiments were performed in triplicate
