Abstract

Bacterial granules grown from mesophilic inoculant were adapted to generate H2 from sucrose under a range of thermophilic temperatures (50, 55, 60, 65, 70°C). In theory under thermophilic temperatures the "Thauer limit" of 4.0 mol H2/mol glucose should be achievable. However, while thermophilic temperatures may be a necessary condition for high yields, this study shows that it was not a sufficient condition. The stability and maintenance of dark anaerobic biohydrogen production in the fluidized granular bed bioreactor was achieved.
