Chromatography (HPLC) Instructor: Dr. Hüseyin BOZKURT High Performance Liquid Chromatography (HPLC) is one mode of chromatography‚ the most widely used analytical technique. Chromatographic processes can be defined as separation techniques involving mass-transfer between stationary and mobile phases. Present day liquid chromatography that generally utilizes very small packing particles and a relatively high pressure is referred to as high performance liquid chromatography (HPLC). HPLC utilizes a

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
