Effect of Millimeter-Wave Irradiation on Growth of Saccharomyces cerevisiae

Abstract
Cultures of Saccharomyces cerevisiae were exposed for 4 h to millimeter waves in three frequency ranges between 41.650 and 41.798 GHz. The irradiation frequency was stabilized to within ±50 Hz. The temperature difference between irradiated and sham-irradiated samples was maintained to within ±0.01°C. Growth was measured optically during the irradiation, and viability counts were done at the end of the irradiation. At least three experiments were performed at each of 15 frequencies.
