Samenvatting

By introduction of the cefEF genes of Acremonium chrysogenum and the cmcH gene of Streptomyces clavuligerus, Penicillium chrysogenum can be reprogrammed to form adipoyl-7-amino-3-carbamoyloxymethyl-3-cephem-4-carboxylic acid (ad7-ACCCA), a carbamoylated derivate of adipoyl-7-aminodeacetoxy-cephalosporanic acid. The cefEF gene of A. chrysogenum encodes a cephalosporin C transporter that belongs to the Major Facilitator Superfamily. Introduction of cefT into an ad7-ACCCA-producing P. chrysogenum strain results in an almost 2-fold increase in cephalosporin production with a concomitant decrease in penicillin by-product formation. These data suggest that cephalosporin production by recombinant P. chrysogenum strains is limited by the ability of the fungus to secrete these compounds. (c) 2008 Elsevier Inc. All rights reserved.
