FIELD: genetic engineering, microbiology. SUBSTANCE: invention proposes fragment of DNA PCG-12 encoding synthesis of $$$-galactosidase. This fragment is used for construction of plasmid pPCG-12 and the strain Penicillium canescens VKPM F-715 that is a producer of $$$-galactosidase. Proposed strain accumulates up to 190-220 U/ml $$$-galactosidase in cultural fluit on medium with beet pulp and $$$. EFFECT: increased synthesis of enzyme. 2 cl
