AbstractThe biohydrogen production from anaerobic fermentation was studied with thermophilic bacterium Carboxydothermus hydrogenoformans using carbon monoxide (CO) dissolved in fermentation broth as the substrate. Bacterium growth model, decay efficient and the maximum specific growth rate were observed based on the experimental study of biomass growing, flocculation and microbial characteristics. The results indicated the feasibility of continuous anaerobic fermentation for hydrogen production from CO with C. hydrogenoformans due to its good hydrogen yield and flocculation ability. Furthermore, by investigating the effect of procedure parameters during CO fermentation, the optimal feed/microorganism was proposed and the maximum CO concentration was observed to avoid CO inhibition which was the key factor to consider in the study of continuous biohydrogen production from CO fermentation.
