Abstract

Acetic acid fermenters in submerged culture are most currently used in vinegarmaking industry. However, they have the disadvantage of being open to the atmosphere with the subsequent evaporation losses of volatile compounds. This paper studies an acetic acid fermentation reactor equipped with a closed gas recycling system which prevents any loss of volatile compounds due to evaporation. Experiments have been conducted in two different operation regimes: fed-batch and continuous. Operation protocols are detailed for both cases, paying particular attention to optimum performance conditions, and comparison of yields and acetification rates.
