Popis: The influence of exogenous RNAse on the dynamics of the acid formation by the industrial strain 8R-A3 of Lactobacillus plantarum, its antibiotic sensitivity and antagonistic activity was studied. In the presence of the RNAase growth stimulating dose both a decrease of the culture lag-phase and a more intensive accumulation of lactic acid in the incubation medium resulting in an increase of the Lactobacillus antagonistic activity were observed. It was shown that RNAase increased the Lactobacillus stability to tetracycline and erythromycin by 32 to 57 per cent as compared to the control.
