The in vitro hydrogenase activity was determined by using a gas chromatograph (Hewlett Packard 5890 A Series II, column molecular Sieve 5 A, Mesh 60/80). As described before [Happe and Naber, 1993], methylviologen reduced by sodium dithionite was used as electron donor. One unit is defined as the amount of hydrogenase evolving 1 pmol Hi-min1 at 25°C. [Pg.119]

The kinetics of the elementary processes of electron transfer in the photochemical hydrogen evolution with hydrogenase using cytochrome C3 and methylviologen as carriers have been reported." The results indicate that cytochrome C3 is reduced by reduced methylviologen (MV ), and that this is followed by rapid electron transfer from C3 to hydrogenase. Molecular hydrogen has been obtained... [Pg.413]

The anodic and enzymatic oxidation of hydrogen in biofuel cells has been investigated to achieve efficient energy conversion. Hydrogenase (EC 1.98.1.1), a protein containing FeS-clusters, oxidizes H2 with reduction of methylviologen. The reoxidation of the reduced mediator in deaerated solution gives a concentration-dependent oxidation current (Varfolomeev and Bachurin, 1984). This system has been adapted for analytical purposes by Boivin and Bourdillon (1987). The enzyme was attached covalently to the surface of a carbon electrode. [Pg.156]
