The radiofrequency radiation is considered to be a stress factor in living biological systems. In this work we study the effects of the radiofrequency on different colonies of bioluminescent $Vibrio harveyi$ bacteria subject to 100 and 900 MHz at three different growing temperatures. For the experiment two different 50 $\Omega$ transmission lines are built. The bioluminescent radiation of the vibrio presents an emission peak at about 480 nm, but under RF stresses, the peak shifts towards longer wavelengths. Moreover, the bacteria under the stress of 900 MHz survive for a longer time with respect to the control and to the 100 MHz likely because of the activation of the persistent factor of the bacteria.
