Unlike these glass containers, Petri's dish had a lid that fit securely over the dish to protect the culture growing inside. When an electric current is passed through an aqueous solution containing an electrolyte, the water molecules decompose via an oxidation–reduction reaction. In other words, Petri dishes are used to support the growth of microorganisms. The normalized performance pre-dictions for Synthetic Petri Dish are shown with green diamonds Most scientists used shallow bowls or bottles, which were awkward to work with and subject to contamination. Two days later, after they had been pulled from the oven, we observed the findings.
