Flexible Plastic Bioreactors for Photobiological Hydrogen Production by Hydrogenase-Deficient Cyanobacteria

摘要

Uptake hydrogenase mutant cells of the cyanobacte-rium Nostoc sp. PCC 7422 photobiologically produced H2 catalyzed by nitrogenase for several days in H2-barrier transparent plastic bags, and accumulated H2 in the presence of O2 evolved by photosynthesis. Their H2 production activity was higher in the sealed flexible bags than in stoppered serum bottles of fixed gas volume.
