Abstract
In order to obtain pectinase from hyperproducing strains, Penicillium expansum was mutated with UV and NTG. The selected mutants were analyz ed for pectinolytic enzyme production and compared with the parental l ine. Mutants with up to a twofold increase in pectin lyase or polygala cturonase activity were obtained. Mutant P462 presented a two-fold inc rease in activity of both enzymes.
