    Resumen:
    Given the highly reduced state of carbon in glycerol and its availability as a substantial byproduct of biodiesel production, glycerol is of special interest for sustainable biofuel production. Glycerol was used as a substrate for biohydrogen production using the hyperthermophilic bacterium, Thermotoga maritima and Thermotoga neapolitana. Both species metabolized glycerol to mainly acetate and hydrogen. At glycerol concentrations of 2.5 g/L, hydrogen was produced with a yield of 2.75 and 2.65 mol H-2/mol glycerol consumed by T. maritima and T. neapolitana respectively. Additionally, the effect of initial pH (ranging between pH 5.0-8.5) and yeast extract concentrations (0.5, 1, 2, 4 g/L) on glycerol fermentation by T. neapolitana was investigated in batch systems. An initial pH value of around 7 was optimal for hydrogen production by T. neapolitana. Lower concentration of yeast extract resulted in a lower H-2 production, however increasing the concentration from 2 to 4 g/L did not affect H-2 production. (C) 2012 Published by Elsevier Ltd. Selection and/or peer-review under responsibility of Canadian Hydrogen and Fuel Cell Association.
