A new type of immobilized-cell photobioreactor with internal illumination by optical fibres

  • Published:
Biotechnology Techniques

Summary

A prototype of an immobilized-cell photobioreactor based on a composite agar layer/microporous membrane structure is described. This photobioreactor has been tested for hydrogen-gas production using viable cells ofRhodospirillum rubrum and a phosphate buffer supplemented with malate and glutamate as nutrient medium. The major problem was the high diffusional resistance of the immobilized-cell layer at high cell population. The device has been patented and might be readily applied to other light-dependent bioreactions having more short-term economic interest than hydrogen photoproduction.
