Abstract:

Propionibacterium freudenreichii subsp. shermanii 1 and 4 were immobilized in the livingstate in 2, 3 and 4% alginate gels, in 2, 4 and 6% carrageenan gels, in 2, 4 and 6% carrageenan/locust bean gum gels and on ceramic support. 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
