7-aminocephalosporanicacid (7-ACA) is convenient starting material for the industrial production of various kinds of semisynthetic cephalosporin antibiotics. In many cases, chemical modifications at the C-7 position is required. Industrially, 7-ACA is derived by chemical or enzymatic deacylation from cephalosporin C, which is fermentatively produced by Acremonium chrysogenum. 7-ACA is a stable only at neutral pHs, enzymatic manipulations are desirable for chemical modifications in the production of cephalosporin related compounds.
