Abstract: Six different industrial nitrogen sources were tested in order to obtain an increase of cephalosporin C titres by Cephalosporim acremonium in a complex medium. Production and degradation of cephalosporin C using soybean as a nitrogen source were studied in this work too. The sources of raw material tested were: casein, lactalbumin, soybean meal, corn gluten and cottonseed. Fermentation occurred in 250ml fermenter flasks at 28 degreesC on a rotatory shaker at 250rpm. The raw material were added in a concentracion of 4 g/L as total nitrogen. The highest cephalosporin C concentration was obtained when soybean was used as nitrogen source. The kinetic data showed than maximum cephalosporin C production was obtained when the fermentation reached 144h (0.93g/L). At the end of fermentation the cephalosporin C concentration dropped to 0.39g/L.
