摘要：
A stable continuous method for producing ethanol from anaerobic fermentation of a gaseous substrate containing at least one reducing gas in a liquid nutrient medium; supplying the gaseous substrate to the bioreactor. The free acetic acid concentration in the bioreactor is maintained at less than 5 g/L free acid. This method allows ethanol to be produced in the fermentation broth in the bioreactor at a productivity of greater than 10 g/L per day. Both ethanol and acetate are produced in a ratio of ethanol to acetate ranging from 1:1 to 20:1.
