Study type: Medical/biological study (experimental study)

Effect of microwaves on survival of some bacterial strains. med./bio.

Published in: Acta Microbiol Immunol Hung 1996; 43 (4): 371-378

Aim of study (acc. to author)

The work deals with the effects of microwave irradiation on the reproductive characteristics of Pseudomonas aeruginosa, Pseudomonas acidovorans, Staphylococcus aureus, and Staphylococcus epidermis, and with a comparative analysis incorporating the effects of the application of conventional heat on the reproduction of these microorganisms.

Main outcome of study (acc. to author)

The work lead the authors to the conviction that microwave radiation portrays a different effect in liquid media than thermal heat. As a conclusion, they can say that microwave radiation inhibits bacteria with an effect which is different from thermal heat, and that the amount of liquid in the medium plays an important role in the absorption of the energy created by microwave radiation.
