Growth Curves of the BI and clpP-AUU Strains.
Cells grown in TAP medium at 60 μE m−2 sec−1 were diluted at 2 × 105 cells per mL in fresh medium and placed at 320 μE m−2 sec−1 with (clpP-AUU, open triangles; BI, X's) or without (clpP-AUU, filled diamonds; BI, filled squares) CO2 bubbling (5% in air).
