Screening of microorganisms for improvement of beta-galactosidase production

The strain of Penicillium notatum 1 most effective for producing beta-galactosidase (see lactase 3.2.1.23), was selected out of 110 moulds belonging to 15 different species, by the test-tube microculture method. The dynamics of beta-galactosidase synthesis was investigated in P. notatum 1 during its culture by submerged method.
