Summary
Light has been found to stimulate the production of hydrogen sulphide in the unicellular blue-green alga Synechococcus lividus Copeland (axenic clone Y 52). The culture was initially isolated in 1964 from one of the Fairy Springs, Lower Geyser Basin, Yellowstone National Park. The cells were collected at 52° C and the thiosulphate ion content of the water was probably about 9.0 p.p.m. (ref.

SUMMARY
Under anaerobic conditions and in the absence of CO2, the thermophilic blue-green alga Synechococcus lividus Y52-s, evolved hydrogen sulfide in both darkness and light. The mechanism of this process was investigated and compared with photo- and dark reductions in organisms representing several phyla. The photoproduction of H2S from either sulfate or thiosulfate was inhibited by 3-(3,4-dichlorophenyl)-1, 1-dimethyl urea (DCMU) and carbonyl m-chlorophenyl-hydrazone (m-Cl-CCP). The inhibitory effect of DCMU showed the requirement for photosystem II as electron donor. Inhibition by m-Cl-CCP also implicated ATP as an energy source. Monofluoroacetate partially inhibited photoproduction of H2S. This indicated that oxidative metabolism may act us a source of electrons to reduce the photooxidant under certain conditions. Thiosulfate acts only as electron acceptor and is reductively cleaved to S= and SO3=. Thiosulfate and sulfate appeared to replace CO2 in the light and O2 in darkness as electron acceptors. The phosphorylation uncouplers dinitrophenol and m-Cl-CCP stimulated dark H2S production.
