STABILIZATION OF BIOLOGICAL PHOTOSYSTEMS - CONTINUOUS REACTOR USE FOR HYDROGEN PRODUCTION THROUGH BIOPHOTOLYSIS OF WATER
The key point and limiting step for the use of photosynthetic systems in direct bioconversion of solar energy is the low stability of their functions. Immobilization can be a tool for increasing the longevity of biocatalysts and allow their use in bioconversion processes such as photoproduction of hydrogen gas from water using solar energy. Chloroplast membranes have been immobilized within various supports. A detailed study of these immobilized chloroplast membranes has been done. The use of continuous flow of reactors allowed to study the real functional stability of photosynthetic systems. The efficiency of combined systems (chloroplast membranes hydrogenase) has been tested. Coimmobilization of biocatalysts improves considerably the H-2 photoproduction. The economic feasibility of combined systems to produce hydrogen has constrained us to use an hydrogenase exhibiting no inhibition in presence of molecular oxygen. The stabilization of a bacterial photosynthetic activity was also studied and photoreactors were built in order to produce a high added value molecule through a light energy dependent process.
