✦ Synopsis

Photoinduced hydrogen evolution with hydrogenase from Desu&ouibrio culgaris (Miyazaki) by the combination of three component system consisting of triethanolamine, zinc-tetraphenylporphyrin tetrasulfonate (ZnTPPS,) znd methyl viologen was irsvestigated in c.%lonic surfactant, cetyltrimethy!ammonium bromide (CTAB), anioni i surfactant, sodium dodecyl sulfate (SDS) or non ionic surtktant, Triton X-100 micellar solution by steady state irradiation. The rate of photoreduction of methyl viologen increast:d by the addition of surfactants, especially CTAB. The back electron transfer reaction from reduced methyl viologen to ZnT'ZP& cation radical was strongly suppressed by the addition of various surfactants, especially ionic surfactant CTAB or SDS. The effective hydrogen evolution from reduced methyl viologen with hydrogenase was accomplished in the presence of CTAB or Triton X-100 micelle.
