A total of 37 growth experiments were conducted at 1 nW/cm², 27 with and 10 without MW radiation. Further 33 runs were performed at 5 pW/cm².
|Kammer||The thermostatted metallic irradiation chamber, coupled by a flexible waveguide with a standardised millimeter wave set-up [Grundler et al., 1983], was mounted on the stage of a scanning microscope.|
|Aufbau||The radiation was guided through a tapered gold-coated quartz needle broadened by quartz carrier plates on both sides and radiated out of a slot (0.4 mm x 1.7 mm) on which the cells were spread in a monolayer. Yeast cells were fixed to the lower surface of a thin transparent agar layer (0.2 mm) filling the inner part of a smaller plastic ring. The agar layer and the cells rested on the quartz needle and the carrier plates. At the opposite surface of the quartz needle, a broader opening for microscopic viewing was covered with a fine metallic mesh suppressing RF leakage.|
|Zusatzinfo||The MW field in the radiating slot was monomodal, and the EF was polarized in the y direction, surrounded by the MF in the x-z plane.|
Die Mikrowellen-Befeldung beeinflusst die Zellwachstums-Rate der Hefe S. cerevisiae in einer Frequenz- und Intensitäts-abhängigen Weise. Das Zellwachstum wurde in einem Bereich von 10-20% gehemmt bzw. erhöht.
