Fig. 6.

Growth rate of WT cells and Δgox mutant line #43 and #46 grown for 24h under HC conditions (5% CO₂), 24h under LC conditions (0.04% CO₂), and returned for 24h to HC conditions. OD₇₂₀ measurements were performed every hour by the Multi-Cultivator system (Photons System Instruments). Shown are means of three biological replicates with standard error. Significant differences to initial growth (HC) within one cell line were determined with a two-tailed Student’s t-test and are indicated by a (P < 0.01) and b (P < 0.001). Significant differences between the mutant and corresponding WT values could not be detected by t-test.
