To investigate the effects of millimeter wave exposure (MMW) on DNA organisation of Escherichia coli at logarithmic and stationary growth. DNA organisation (i.e. different genome conformational stages (GCS) such as different degrees of DNA condensation) was analysed by the AVTD (anomalous viscosity time dependence) method.
|Exposure duration||10 min|
The temperature in cell suspensions was controlled during exposure and no heating was observed. Comparable cell densities were warranted. Stationary cells responded by significant increase in AVTD to MMW-exposure, whereas logarithmic cells revealed a significant decrease in AVTD. On the strength of the obtained data the authors suggest that cell-to-cell communication might be involved in the response of cells to weak MMW-exposure.
