Abstract
Biological hydrogen production from anaerobic waste fermentation possesses potential benefits in simultaneously reducing organic wastes and generating sustainable energy sources. Three kinetic-based steady-state models for anaerobic fermentation of multiple substrates, including glucose and peptone, were evaluated. Experimental results obtained from a continuous stirred tank reactor (CSTR) were primarily used for model evaluation. The dual-substrate steady-state model developed and the associated kinetic parameters estimated in this study successfully described the anaerobic growth of hydrogen-producing bacteria. The model was able to capture the general trends of consumption of substrates and accumulation of products, including formate, acetate, butyrate, and hydrogen, at dilution rates (D) between 0.06 and 0.69/h. According to the model, the adverse effects of endogeneous and peptone metabolism on net hydrogen production can be minimized by increasing D. For the operational conditions of D > 0.69/h, however, substantial washout of hydrogen-producing bacteria from the CSTR was observed, and it resulted in a rapid drop in hydrogen production rate as well.
