Low power microwave exposures at 968MHz increase the growth rate of Breanomyces bruxellensis yeast cells

In this study we investigated the effects of applied electromagnetic radiation (EMR) on Breanomyces bruxellensis WLP644 yeast cells under aerobic conditions. Yeast cells were continuously exposed for 7 hours to microwave radiation at the frequency of 968MHz and powers 0.0dBm and 17.0dBm using the custom made Transverse Electro-Magnetic (TEM) cell. Yeast culture growth was monitored using the spectrophotometry method. The changes in the growth rate induced by microwave exposures were compared to the control (non-radiated) yeast samples. The findings reveal that microwaves at 968MHz and powers 0.0dBm and 17.0dBm increase the rate of growth in studied Breanomyces bruxellensis yeast cells.
