The production of hydrogen gas through photolysis of water catalyzed by intact cells, enzymes, or synthetic catalysts is investigated. Many functional systems of each type were discovered. The importance of removing oxygen, which is an inhibitory by-product, is shown. This must be done with an oxygen adsorbent in situ rather than in a separate compartment. Using mixed systems, many possible different electron donors, electron transport carriers, and different sources of hydrogenase are shown to work. The hydrogenase could be replaced by platinum or palladium asbestos. A very important finding is that deazaflavins catalyze the photoreduction of methyl viologen by amino acids. This leaves open the possibility that protein waste products from garbage or from some industries could be used to produce hydrogen from water as an important auxiliary energy source.
