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.
研究了外源核糖核酸酶对植物乳杆菌工业菌株8R - A3产酸动态、抗生素敏感性及拮抗活性的影响。在核糖核酸酶生长刺激剂量存在的情况下,观察到培养延迟期缩短,且在培养介质中乳酸积累更强烈,导致乳酸杆菌拮抗活性增强。结果表明,与对照相比,核糖核酸酶使乳酸杆菌对四环素和红霉素的稳定性提高了32%至57%。
