Ammonia consumption, glucose utilization,production of propionic and acetic acids, biosynthesis of vitamin B12 and cell release rate wereexamined. A significant increase of productivity of propionic acid and decrease of biosynthesisof vitamin Bj2 using immobilized cells were observed. The best results were obtained in thefermentation with strains immobilized in 4% alginate gel, when applied for the third time. Inthis case, production of propionic acid was 50% higher in comparison with free cells and biosynthesis of vitamin Bj2 was lower or the same as in the control}, type={Text}, title={Batch Propionic Acid Fermentation Using Propionibacterium sp.
