Influence of low intensity 2,450 MHz microwave radiation upon the growth of various micro-organisms and their sensitivity towards chemical inactivation.
The non-lethal effects of 2,450 MHz radiation upon vegetative cell of P. aeruginosa and S. aureus have been assessed at low power intensities (1 joule min-1 ml-1) over a prolonged time period (16 h). Results indicated that the cell envelope was a primary target for such radiation. Growth of micro-organisms in the presence of microwaves produced minor structural changes in their cell envelopes which resulted in an alteration of preservative sensitivity. Such changes were not sufficiently great as to result in any alteration of specific growth rates during continuous microwave exposure, neither was motility nor cellular morphology affected.
