title: [Effect of cultivation temperature on nucleic acid level in bacteria Listeria monocytogenes and Yersinia pseudotuberculosis].
abstract: The relationship between the multiplication of bacteria, the content of nucleic acid and the specific rate of their growth during their batch cultivation in nutrient broth and mineral medium at temperatures of 37 degrees C and 4-6 degrees C was studied in the causative agents of saprozoonotic infections with L. monocytogenes and Y. pseudotuberculosis used as typical representatives of such bacteria. The content of DNA was shown to remain practically unchanged after the alteration of cultivation temperature and the conditions of nutrition. The linear relationship between the content of RNA and specific growth rate was registered both at 37 degrees C and 4-6 degrees C. However a higher content of RNA at low temperatures was found to correspond to one and the same specific growth rate, which was linked with the additional synthesis of this nucleic acid.
