Abstract Surfactin, as a green biosurfactant, can be widely applied in various fields. However, the severe foaming arising in the fermentation process obstructed the industrial production of surfactin. Therefore, different strategies were explored to solve this problem in a 7L bioreactor. The results showed that excessive addition of antifoam would inhibit microbial growth and increase the production costs. The surfactin yield were 1.42g/L and 1.96g/L by using organic silicon and soybean oil as antifoams, respectively. However, foam fractionation in a modified bioreactor was more economical and effective for controlling the foaming and separating surfactin in situ. After fermentation coupled with foam fractionation, the surfactin yield was 2.39g/L. Based on the strategy of foam fractionation, the surfactin yield increased to 3.45g/L after controlling pH at 7. Moreover, it increased to 5.07g/L after controlling pH at 7 and DO≥20%. Furthermore, the surfactin yield increased to 6.04g/L by coupling foam fractionation with the regulation of pH, DO, and feeding (a constant rate of 1.39ml/min), which was 4.25 times higher than using antifoam. An efficient strategy is provided to control the foaming during fermentation and increase the surfactin yield, which can promote the industrial production of surfactin.
