[The effect of Bacillus intermedius RNAse on the multiplication of Candida tropicalis yeasts].

Abstract

The effect of Bacillus intermedius RNAse on the reproduction of Candida tropicalis and synthesis of the main biopolymers in the yeast cells. It has been found that stimulating action of the enzyme appears at the concentration of 10(-5)-10(-6) mg/ml and does not depend on the physiological state of the sowing culture. The connection between the increase of the ionic penetration and stimulation of the RNA and proteins synthesis in the yeast cells subjected to the RNAse action is shown. The mechanism of chromatine-associated RNA-polymerase activation is suggested to include the alteration of the ionic penetration of cells under the RNAse action.
