Penicillin Biosynthesis Structure Fermentation Process

Penicillin production by continuous fermentation has been attempted but it has been difficult due to instability of the production strains A batch fill and draw system has been suggested as an alternative In this process 20-40% of the fermentation contents is drawn off and replaced with fresh nutrient solution This process may be repeated up Get price
