IV. MATERIALS AND METHODS Process Description The classical penicillin production process is an aerobic fermentation in fed batch fermenters made with some Penicillium strains‚ usually Penicillium chrysogenum (Nielson‚ 1997) that transforms substrates rich in carbohydrates into penicillin. As with other antibiotic production processes (Cunha et al.‚ 2002)‚ the penicillin process operated at antibiotics involves four stages. The incubation of the culture strain provides the seed that grows in
