title: On-line high-performance liquid chromatography for the determination of cephalosporin C and by-products in complex fermentation broths.
abstract: A fully automated high-performance liquid chromatographic system was developed for optimization of cephalosporin C production. Using a simple, isocratic, reversed-phase method, cephalosporin C, deacetylcephalosporin C, deacetoxycephalosporin C, penicillin N, methionine and its decomposition product 2-hydroxy-4-methylmercaptobutyric acid were determined. The method worked reliably for 250 h and supplied information on the influence of many parameters of the process.
