FIG. 2.

Time courses for phosphorus (●), glucose (▵), and acetate (◊) in a batch reactor submitted to anaerobiosis (3 h) and an aerobic period. Concentrations of these metabolites were determined in the supernatant of the culture. The intracellular concentration of glutamic acid (■) and cell dry weight (○) are depicted in the inset. A glucose concentration of 0.71 mmol g of cell⁻¹ was used in this experiment.
