✦ Synopsis
The effect of weak extremely-low-frequency (ELF) magnetic fields (sinusoidal, 30 p T amplitude) on the genome conformational state (GCS) of E. coli mutant and wild type cells was studied by using the method of anomalous viscosity time dependency (AVTD) in the 6-37 Hz frequency range. We confirmed the existence of three resonance frequencies of 8.9, 15.5, and 29.4 Hz when mutant cells of K12 ABI 157 strain were exposed. In the same frequency range, the wild type K12 EMG2 cells displayed only two effective windows, with resonance frequencies of 8.3 and 27 Hz. The resonance frequencies differed significantly ( P < .001-.OOOOOl) in the strains studied, whereas other resonance parameters did not. It was concluded that mutations in the AB I 157 strain resulted in a significant rearrangement in the ELF action spectrum, including the appearance of a new resonance.
