Appendix 1—figure 20. Confocal microscopy of liquid TAP-grown CC-5357, which has a Venus labeled RbcS1, treated without (Panel A) and with H₂O₂ (Panel B), showing no change in localization of rubisco.

Cultures were harvested from photobioreactors in the morning (two hours after the start of illumination) and diluted by half with fresh TAP media – without (control) or with addition of 100 μM of H₂O₂. After ten hours in low light (~85 μmol photons m^–2 s^–1), cells were then viewed with the confocal microscope. Scale bar = 10 μm.
