The anaerobic bacterium P. productus was known to produce acetate from CO, C02 and H2. In this research the acetate f formation from waste gas was studied. For this research, kinetic parameter study on CO conversion were carried out. From t this study maximum CO conversion rate of 39.3 mmol/L . hr . 0.0 and Km of 0.578 atm were obtained. Also the effect of c CO refreshment, N source, initial pH and c비ture temperature on acetate formation were studied. Acetate formation in 5L lab s scale fermenter was tested and specific acetate production rate of 0.48 g/L-hr-O.O. was obtained and the acetate c concentration was 21 g/L.

The anaerobic bacterium P. productus was known to produce acetate from CO, $CO_2$ and $H_2$. In this research the production of acetate at high concentration from carbon monoxide was studied. In this research the effect of $CO_2$, $H_2$, and CODH co-factor on cell growth and acetate production was studied. Also the toxicity of acetate on cell growth was examined. Acetate formation in lab scale fermenter was tested and specific acetate production rate of $0.43\;g/L \;{\cdot}\;hr\;{\cdot}\;O.D.$ was obtained and the concentration of the acetate obtained in a fermenter higher than 40g/L.
