Butyric acid is a valuable intermediate to be converted to butanol and has been biologically produced in pure culture systems. However, pure culture is vulnerable to contamination and requires high cost for construction and operation; thus, mixed culture systems are required for mass production. The objective of this study is to determine optimum conditions of a bioreactor to produce butyric acid from molasses In mixed culture. Batch tests are performed to investigate optimum temperature, substrate load, and cell concentration; and a continuous stirred-tank reactor (CSTR) is operated to determine optimum hydraulic and cell residence times. The results of the batch test show that at pH 6 and 35℃, the fermentation enables the highest production of 4.4 g/l with a yield of 0.088 g/g. Experiments are on-going to obtain other optimum conditions, which will be presented on the conference. This study will provide optimum design and operating factors of the mixed culture bioreactor to mass produce butyric acid stably and economically.
