Abstract excerpt

The CT1 mutant of Penicillium occitanis hyperproduces extracellular pectinases constitutively since it secretes pectinases even on glucose-containing medium. We show here that all other hydrolytic enzymes remain at low activities in CT1, confirming the specificity of the regulatory mutation towards pectinases. We isolated, by RT-PCR and through the construction of a cDNA library, three fragments coding for: a...
