title: [Influence of cultivation conditions on the synthesis of trypsin inhibitor in the submerged culture of Actinomyces janthinus 118].
abstract: The influence of mass exchange and cultivation temperature on the synthesis of trypsin inhibitor in the submerged culture of Actinomyces janthinus was studied. Mass exchange parameters of the fermenter varied from 0.72 to 3.7 g O2 l/hr without oxygen limitations, and cultivation temperature ranged from 25 to 34 degrees C. The growth pattern, dynamics of substrate consumption and synthesis of trypsin inhibitor by the culture of Act. janthinus were shown to depend on mass exchange and cultivation temperature. With an increase in mass exchange the inhibitory activity reached maximum earlier but did not rise in its absolute value. With a temperature increase the inhibitory activity grew by 65%.
