Abstract


Three strains of Cephalosporium acremonium with different potential of cephalosporin C production show differences in the levels of sulphur amino acid metabolic enzymes. The regulation of these enzymes is also different in the strains. In the superior producing strain two enzymes directly involved in cysteine synthesis are the least susceptible to repression by methionine. In this strain cystathionine metabolizing enzymes seem to favour cysteine synthesis. Antibiotic producing strains, in contrast to the non-producing strain, are highly sensitive to chromate.
