General Information

General Information Comment Organism
malfunction two industrial strains of Penicillium chrysogenum a penicillin (PC-pen)- and a cephalosporin producing (PC-ceph) are used in which the NADPH-dependent GDH is deleted by replacing 0.8 kb of the C-terminus of the gdhA gene with the hygromyin B resistance marker, resulting in PC-pen-DELTAgdhA and PC-ceph-DELTAgdhA. The two strains are isogenic except for the insertion of the Streptomyces clavuligerus expandase gene into the genome of PC-ceph. It is shown that this genetic modification results in a radical change in morphology Penicillium chrysogenum
