title: [Physiological characteristics of the strains of Cryptococcus deffluens--producers of penicillin acylase].
abstract: A fermentation medium balanced by the main components was developed for Cryptococcus diffluens strains producing penicillin-V-acylases (PA). It was shown that the culture needed for production of the enzyme was inductor, which was phenoxyacetic acid (POAA). Additional introduction of ethanol to the medium provided an increase in production of PA by 36 per cent and the culture growth by 25 per cent. Introduction of one of the following substances to the medium with POAA and ethanol i.e. (CN3COO)2Ca, FeSO4, proline or asparagine provided an additional increase in the production level of PA by 24 to 94 per cent. The use of the medium varieties will permit one to isolate highly productive cells of the culture.
