Iy. Belyaev et al., EVIDENCE FOR DEPENDENCE OF RESONANT-FREQUENCY OF MILLIMETER-WAVE INTERACTION WITH ESCHERICHIA-COLI K12 CELLS ON HAPLOID GENOME LENGTH, Electro- and magnetobiology, 12(1), 1993, pp. 39-49
The method of anomalous viscosity time dependence (AVTD) was used to s
tudy the influence of millimeter electromagnetic radiation (EMR) on th
e genome conformational state (GCS) of Escherichia coli K12 cells. Str
ain N99 of wild-type, lysogenic strains N99(lambda) and N99(lambda,lam
bdaimm434bio10) were used. In the 41.28-41.37 GHz and 51.73-51.79 GHz
ranges the resonance effect of low-intensity EMR (10(-10) W/cm2) on th
e GCS of N99 cells was shown. The resonance frequencies were 41.324 +/
- 0.001 GHz and 51.765 +/- 0.002 GHz, respectively. The insertion in b
acterial chromosome of prophage X [strain N99(lambda)] and prophage la
mbdaimm434bio10 [strain N99(lambda, lambdaimm434bio10)] reduced both r
esonance frequencies considerably. The decrease of both resonance freq
uencies was proportionate to the increase of the haploid genome length
. Shifts of the resonance frequency were not accompanied by change in
the sign of effective circular EMR polarization. The results indicate
that the frequencies of resonance interaction of E. coli cells with lo
w-intensity millimeter waves are determined by the genome structure. A
physical model was suggested to describe the observed shift of the re
sonance frequency.
