Average specific productivity of succinate in the anaerobic stage in flask experiments. The combination of glycerol was based on the two-stage strategy. (A) Aerobic stage: pure glycerol, anaerobic stage: pure glycerol. (B) Aerobic stage: pure glycerol, anaerobic stage: crude glycerol without simple purification. (C) Aerobic stage: pure glycerol, anaerobic stage: crude glycerol with simple purification. (D) Aerobic stage: crude glycerol without simple purification, anaerobic stage: crude glycerol without simple purification. (E) Aerobic stage: crude glycerol with simple purification, anaerobic stage: crude glycerol with simple purification
