dc.description.abstract | The effects of hydraulic retention times (HRTs-6, 3 and 2 h) on H-2 production, operational stability and bacterial population response in a continuously stirred tank reactor (CSTR) were evaluated using galactose. A peak hydrogen production rate (HPR) of 25.9 L H-2/L-d was obtained at a 3 h HRT with an organic loading rate (OLR) of 120 g/L-d, while the maximum hydrogen yield (HY) of 2.21 mol H-2/mol galactose was obtained at a 6 h HRT (60 g galactose/L-d). Butyrate was dominant and the lactate concentration increased as HRT decreased, which significantly affected the HY. Biomass concentration (VSS) decreased from 16 to 3 g/L at a 2 h HRT, leading to failure. A 3 h HRT supported the favorable growth of Clostridium species, as indicated by an increase in their populations from 25.4% to 27%, while significantly reducing Bacilli populations from 61.6% to 54.2%, indicating that this was the optimal condition.
