Abstract:

The aim of this study was to evaluate the performance of an autotrophic denitrification during an anaerobic fermentation process usingH2/CO2 mixture gas (80:20, v/v) as sole energy source. Chemostat reactors were operated with anaerobically acclimated hydrogenotrophic methanogens culture broth. Reactors were connected with different volume of H2/CO2 gas bag (7L; 9L; 10L and 12L/d). Results showed that environmental factors such as gas mixing duration and H2/CO2 volume had effect on denitrification. The nitrogen gas (N2) volume increased with the mixing duration and the H2/CO2 gas volume. The presence of carbon dioxide in the mixture feeding gas maintained the pH stable within all experiment duration. This should help to appreciate the autotrophic denitrification with H2 as electron donor when the system is utilized for nitrogen removal in a biodegradation process.
