The green algal Chlamydomonas reinhardtii under the sulfur deprived condition is to stop water splitting, which is mediated by photosystemⅡ (PSⅡ) breakdown in the light. The rate of oxygen evolution drops below the rate of respiratory oxygen uptake, and the environment of algal culture is converted from aerobic to anaerobic condition. The prompt conversion to anaerobic condition causes activation of the hydrogenase and hydrogen production by the activated hydrogenase subsequently. We assumed that the photosynthetic capacity for hydrogen production would differ according to light intensity. Accordingly, we investigated the relationships between hydrogen production, induction time of sulfur deprivation, the uptake rate of residual sulfate and residual PSⅡ activity depending on light intensity. |
