title: [OPTIMIZATION OF CULTIVATION CONDITIONS OF PENICILLIUM TARDUM--THE α-L- RHAMNOSIDASE PRODUCER].
abstract: The influence of some technological cultivation parameters of Penicillium tardum to synthesize of the extracellular α.-L-rhamnosidase were studied. It was shown that rhamnose (0.8%), yeasts autolysate (0.2%), temperature of the cultivation 25 degrees C, pH 5.0 are necessary for maximal α-L-rhamnosidase production. The enzyme reaches the maximal activity level in 96 hours with sulphitic number equal 0.44. At cultivation of P. tardum in the picked up conditions the α-L-rhamnosidase synthesis has raised in 4 times.
