Research on mechanism of photobiological hydrogen production and electricity generation using microalgae based fuel cells
In our lab,it was observed that Platymonas subcordiformis,a marine green alga,can produce hydrogen high efficiently under regulation of a proton uncoupler CCCP.In this paper,microalga based fuel cells without and with mediator were constructed to characterize kinetics of photobiological hydrogen evolution from P.suhcordiformis,investigated hydrogen metabolism and realize photo-electricity conversion.By studying the kinetics curves of hydrogen evolution and activities of hydrogenase and PSII,it was shown that the duration and amount of hydrogen production depended on how to keep high activities of hydrogenase and PSII.So a microalgae based fuel cell with mediator was used to investigate hydrogen metabolism such as photosynthetic electrons delivering and activity characterization of key reaction centers,and also realized photo-electricity conversion,which approved feasible.
