| 中文摘要 | The marine green alga Platymonas subcordiformis can produce a significant amount of hydrogen under anaerobic condition and the addition of a proton gradient uncoupler, carbonylcyanide-m-Chlorophenylhydrazone（CCCP）. About 7.54ml H2 was produced at 3x106 cells/ml for 12h in a 760ml photobioreactor when 15μM CCCP was added at the start of light illumination. During the stage of hydrogen evolution, the extracellular pH and the photochemical activity of PSII reduced from 7.62 to 7.49 and from 0.342 to 0.002, respectively. The system holds at a very low oxygen level. These results indicated that the proton gradient uncoupler CCCP can facilitate the proton transfer across the thylakoid membrane, thus enhance the accessibility of H+ to hydrogenase, and keep anaerobic condition during hydrogen production through markedly inhibition of the PSII activity. |
