Hydrogen Photoproduction by Rhodopseudomonas palustris 42OL Cultured at High Irradiance under a Semicontinuous Regime

Figure 6

Changes in the Bchl concentration versus the cultivation time and relative H P R 𝑉 achieved in time, under SCR, at 30°C with an irradiance of 480 W m−2. The HRT was 138 hours. The arrow indicates the cultivation time when we withdrew 120 mL of culture volume from the reactor and replaced with an equal volume of fresh medium.
