✦ Synopsis

The present paper presents a study of propionic acid production from whey by using Propionibacterium acidipropionici in batch and continuous fermentation with cell recycle. The experimental investigation is carried through with a biomass concentration (DW) of l l2kg/m 3. The highest propionic acid productivity is 2.14 kg/(m 3 h). Biomass concentration is 9 times as high, propionic acid productivity 6 times as high as compared to batch results.
