| 摘要 | Previously, we found that marine Chlorella pyrenoidosa strain IOAC707S could generate hydrogen (H-2) under nitrogen deprivation in seawater medium, without dark incubation, N-2 flushing or addition of protonophore. In this work, the H-2 yield of C. pyrenoidosa was enhanced, and the mechanism of H-2 photoproduction was investigated. It was found that C. pyrenoidosa could produce H-2 under hypoxic conditions, which indicated the hydrogenase of C.pyrenoidosa could tolerate a low concentration of O-2. Nitrogen deprivation could lower the efficiency of photosyntem (PS) II photochemical activity and PSII oxygenic activities, which were favorable for rapid establishment of anoxia and efficient H-2 photoproduction, and thus significantly enhance H-2 photoproduction of C. pyrenoidosa. Preculture in nitrogen-deprived medium could further increase the H-2 yield of C. pyrenoidosa, for its more severe inhibition of the oxygen-evolving complex, electron transport and photochemical efficiency of PSII, and PSII oxygenic activities, which facilitated the establishment of anaerobiosis and activation of hydrogenase.
