Considering how expensive healthcare is, I wouldn’t be surprised if there aren’t some DIY types also wanting to learn how to make penicillin.
If you want to learn how to make DIY penicillin, here’s what you need to know.
Put a piece of bread, cantaloupe, or citrus fruit in a container in a dark place at 70 degrees F. It should be in a closed (but not airtight) container.
The bread or fruit will start getting a gray mold. This gray mold will eventually turn a bluish-green color. This is the mold that you want for making penicillin!
The greenish-blue mold you grew contains penicillin. Some people call this mold “natural penicillin” and say you can use it immediately. Unfortunately, this isn’t the case.
To get the benefits of penicillin from mold, it has to be further cultured.
Now it is time to move your penicillin mold spores to your “Petri dishes” that have the potato broth in them. There is a very specific method that scientists use for growing cultures. It is called “streaking.”
