The state-of-art and future prospects of BioHydrogen - Photosynthetic Microorganisms as Main Objects -

Abstract

The state-of-art and future prospects of BioHydrogen are overviewed, targeted on photosynthetic microorganisms (photosynthetic bacteria, cyanobacteria and green algae as main objects. We describe here our recent results, mainly hydrogen production with sugar by co-culture of photosynthetic bacteria and anaerobic bacteria. Recent efforts of genetic alteration to enhance hydrogen production in these microorganims are briefly introduced.
