Four chromosomes were resolved by pulsed field gel electrophoresis in Penicillium notatum (10.8, 9.6, 6.3 and 5.4 Mb in size) and in five different strains of Penicillium chrysogenum (10.4, 9.6, 7.3(More)
High penicillin-producing strains of Penicillium chrysogenum contain 6-14 copies of the three clustered structural biosynthetic genes, pcbAB, pcbC, and penDE [Barredo, J.L., Díez, B., Alvarez, E.,(More)
The organization of the genes of the penicillin cluster has been studied in three different mutants of P. chrysogenum impaired in penicillin biosynthesis. The three blocked mutants (derived from the(More)
Mycobiota growing on food is often beneficial for the ripening and development of the specific flavor characteristics of the product, but it can also be harmful due to the production of undesirable(More)
