Fed-batch propionic and acetic acid fermentations were performed in semi-defined laboratory medium and in corn steep liquor withPropionibacterium acidipropionici strain P9. On average, over four experiments, 34.5 g/l propionic acid and 12.8 g/l acetic acid were obtained in about 146 h in laboratory medium with 79 g/l glucose added over five feeding periods. The highest concentration of propionic acid, 45 g/l, was obtained when the glucose concentration was not allowed to drop to zero. In corn… CONTINUE READING
