(i) Possibility of inactivation (ii) Resemblance between the dynamics of heat and microwave treatments (iii) Absorption of the radiation of particular frequencies may affect metabolic processes (iv) Disorders of E. coli growth resulted from EMF of 70.6 GHz and 73 GHz (v) Increased secretion of beta-galactosidase (vi) Highly resistant to EMF & MF due to autoregulation of numerous biological processes (vii) No difference between various field frequencies (probably thanks to slight temperature changes at the cellular level)
