Figure 15From: Evaluation of the effects of Extremely Low Frequency (ELF) Pulsed Electromagnetic Fields (PEMF) on survival of the bacterium Staphylococcus aureusBlock diagram for the experimental procedure: Investigating the effect of ELF PEMF exposure on bacteria Staphylococcus aureus . Step 1: Initial culture on agar (solid medium); Step 2: Making suspension in liquid medium (broth) to a 0.1A OD reading; Step 3: ELF PEMF exposure; Step 4: Seeding the previously irradiated and non-irradiated broth culture on agar (solid medium) to find the number of the bacterial cells which survived the exposure.Back to article page
