Figure 2. The growth rate variation of E. coli after irradiation by EMF at different Rife frequencies programs: (a) programs from group A related to the inhibitory effect of E. coli and group B with anti-bacterial properties (b) Programs from group C with frequencies below 100 Hz, with no anti-bacterial properties stated in the database. Error bars representing standard deviation of triplicate samples.
