The potential productivity of an intended cooperative process for the production of the fuels ethanol and hydrogen was tested in separated trials. The intended process integrates green algae, clostridia, purple bacteria and yeast cells. The green algae produce sugar by photosynthesis from carbon dioxide and sun light. The produced sugar will be fermented to ethanol by yeast. Further the green algae shall function as a light filter, eliminating short waves of the light which are harmful to the purple bacteria located in an inner part of the photo-bioreactor. The purple bacteria produce hydrogen from organic acids which are provided by the fermentation of clostrid...
