The anaerobic bacterium P. productus was known to produce acetate from CO, CO2 and H2. In this research the acetate formation from waste gas was studied. For this research, kinetic parameter study on CO conversion were carried out. From this study maximum CO conversion rate of 39.3 mmol/L.hr.O.D and Km of 0.578 atm were obtained. Also the effect of CO refreshment, N source, initial pH and culture temperature on acetate formation were studied. Acetate formation in 5L lab scale fermenter was tested and specific acetate production rate of 0.48 g/L-hr-O.D. was obtained and the acetate concentration was 21g/L.
