Is this a good method for testing which mouthwash kills the most bacteria?
I'm going to collect oral bacteria and swab it on a petri dish with agar. I will soak a small square or circle of tissue in one mouthwash and place it in the middle of the petri dish. Then I will close it and I don't have an incubator, so I'm just going to put them in a dark place and measure the zone of inhibition or "kill zone" over the course of 5 days. Is that a good way to do it? Will I just kill the bacteria? Please help! Thank you!
