International Conference on Biological Hydrogen Production, Hawaii, United States Of America, 23 - 26 June 1997, pp.295-304
A bio-photoelectrochemical (bio-PEC) reactor containing the photosynthetic bacterium Halobacterium halobium has been constructed. H. halobium contains a retinal protein, bacteriorhodopsin, in its purple membrane that gives protons upon illumination. In this system, the biocatalytic effect of bacteriorhodopsin on photoelectrochemical hydrogen production was determined.
