Metabolic Properties

In anaerobic digestion system, the functional niche of hydrogen-producing acetogens (HPAs) is between acidogenic fermentation bacteria and methanogens. HPAs are quite difficult to be isolated by pure and ampliative cultures due to the obligate anaerobic metabolism property in syntrophic association with methanogenic. In order to enhance the HPAs activities in anaerobic disgestion, the physioecologic and metabolic properties of HPAs under different medium conditions, such as carbon and nitrogen type, influent temperature and pH was investigated in batch cultivation experiments. The result illustrated that under the cultivation temperature of 45°C and pH of 8.0, the butyrate, propionate and benzoate could be utilized by the syntrophic acetogenesis coculture, of which the uptake rate of butyrate was highest. The glucose and sucrose were repulsed however. The metabolic activity of HPAs could be enormously simulated as the mixture of tryptone and yeast was taken as the nitrogen source.
