Notes:
The ability to synthesize extracellular β-galactosidase (EC 3.2.1.23), α-galactosidase (EC 3.2.1.22), β-fructofuranosidase (EC 3.2.1.26) in Penicillium canescens mutant strains (300 cultures) after UV-irradiation has been checked. Most of the investigated mutants had the ability to produce the mentioned enzymes in an increased amount in comparison with initial strain. The ability of extracellular enzyme biosynthesis in P. canescens mutant strains was increased for α-galactosidase on 200%, for β-galactosidase on 275% and for β-fructofuranosidase-220%. The mutant strains were stable during three years of observation, complitely maintaining increased activity.
