Growth DO (control) DO (deg) pH (control) Growth (620 nm) and DO (mg/L) Incubation time (h) The figure above shows a bacterial growth curve (X), change in pH (open triangles), and dissolved oxygen (DO, open squares), caused by a bacterial consortium during pulp paper mill effluent degradation. Note that DO control (filled squares) and pH control (filled triangles) are data from a sterile (no bacteria) experiment. Using the data in the figure above, complete the sentence with the best answer from the list below: The bacteria are probably entering stationary phase at time = 0 at time = 120 h slightly after the time that oxygen concentration drops to 0.3 mg/L when pH is > 7 because oxygen was oversaturated.
