Abstract

The characterization of photobiological hydrogen production for four marine green algae by sulfur-deprived and treated with uncoupler after dark anaerobic incubation was investigated. The four marine green algae couldn't produce any hydrogen gas by sulfur-deprived from medium during direct light illumination. Four marine green algae were treated with 5 μmol/L uncoupler CCCP after dark anaerobic incubation of 32 hours, Platymonas subcordiformis could photoproduce a significant amount of hydrogen gas, Dunaliella salina and Marine Chlamydomonas only could photoproduce extremely small amount of hydrogen gas, and Pyramidomonas sp hardly could photoproduce any hydrogen gas. The change of hydrogen photoproduction rate and PS II photochemical activity of P subcordiformis indicated that part inhibition the PS II photochemical activity makes the photosynthetic oxygen evolution lower than the oxygen consumption by mitochondrion and the system can maintain anaerobic condition, at the same time, algae cells must keep some photochemical activity, which can supply enough electrons to hydrogenase for hydrogen production.
