[Spontaneous mutational background of microorganisms in the absence of substrate].
The dynamics of spontaneous mutagenesis in a population of heterotrophic microorganisms during incubation in the absence of organic substrate was studied. A model of this dynamics was proposed. which is determined by the excitation by an external electromagnetic field of Langmuir proton oscillations activating the tautomeric transitions of nucleotides of DNA. It was shown that the model fits well the experimental data.
