Summary
Hydrogen photoproduction by immobilized cells of the marine photosynthetic sulfur bacterium, Chromatium sp. Miami PBS 1071 was carried out by periodic addition of supplemental sulfide in the reaction system. CO2 was not produced and only H2 was evolved. Hydrogen gas in this immobilized system was continuously produced for at least 300 hrs. at a constant rate. This contrasts from free cell systems where the hydrogen production dropped within 40 hrs. When immobilized cells were grown in the agar gel matrix, high biomass yield was obtained, and rates of hydrogen production up to 6 μ moles/g. gel/hr for 100 hrs were observed. Based on these laboratory experiments, outdoor culturing and hydrogen production was carried out using immobilized cells in 4L reactor systems containing 1.5 kg agar gel.
