How to make Penicillin

Product Information

What you will be left with is impure penicillin. While you could use this right away, it is not pure enough to be fully effective. Basically in this form it can work, but is pretty unreliable. You must perform one further extraction method using ethyl acetate to extract pure penicillin, that way you have a stable antibiotic that will really work. Step 7: Purify the Penicillin Additionally, honey has a low pH level. This works to pull moisture away from bacteria, causing the bacteria to get dehydrated and die off.

When bacteria multiply, their cellular division causes small holes to open up. Newly released peptidoglycans work to reconstruct the walls. Later on, we will provide instructions on how to make penicillin, but did you know that it is not a thing that can cure everything? Take a petri dish and make a mold of agar. Create tiny depressions on it and add drops of penicillin broth into every depression. Inoculate with bacteria that are susceptible to penicillin. Now open the separator funnel and remove the ethyl acetate by allowing it to drip into a sterile container of some sort. Once the ethyl acetate/penicllin mixture has drained fully, you will need to add the potassium acetate to the ethyl acetate mixture. Use about 1 gram of potassium acetate per 100 millilitres of liquid solution.Lilly was particularly successful in making the mold synthesize new types of penicillin by feeding precursors of different structure. Once the fermentation was complete, recovery was also difficult; as much as two-thirds of the penicillin present could be lost during purification because of its instability and heat sensitivity. Extraction was done at low temperatures. Methods of freeze-drying under vacuum eventually gave the best results in purifying the penicillin to a stable, sterile, and usable final form. Cool the glass in an ice bath and pour the ethyl acetate into it. Add 1 percent potassium acetate and mix again; Maybe this September 28, as we celebrate Alexander Fleming’s great accomplishment, we will recall that penicillin also required the midwifery of Florey, Chain and Heatley, as well as an army of laboratory workers. The next part is extracting penicillin. You can do this by removing any solid part of the liquid first. You can filter it through a piece of cloth to make sure it’s just pure liquid you’re transferring to a different container. Make sure the bottom tap of the funnel is closed. Pour the chilled ethyl acetate (500ml) and the strained liquid penicillin into the funnel. Close the top lid of the funnel and shake vigorously for 30-35 seconds.

Adapted for the internet from "The discovery and development of penicillin 1928-1945," produced by the American Chemical Society and the Royal Society of Chemistry in 1999.Penicillin does not cure all illnesses. Penicillin can fight throat, respiratory tract, and skin infections. But it will not save you from broken bones or UIT infections. Do keep in mind that other types of bacteria can be colored yellow, and the only way to know for sure that you have penicillin is by using a microscope. In an apocalyptic situation, you will just have to go with your gut on this one. If you’ve been careful about following the steps laid out here, including sterilizing everything as suggested, then what you have should be penicillin. How to Make Penicillin at Home: The Difficult “Sciencey” Part Step 5: Fermenting Our contributors and writers over the years have included survival experts of all stripes – including a Green Beret Special Forces Medic, a former Navy SEAL, a leading survival instructor who’s been featured on National Geographic and PBS. Every article is either written or reviewed by someone who is an expert in either survivalism, prepping, or homesteading (or all three) and our goal is to be as practical and educational as possible.

Pour the liquid from the fermented flask through the strainer and the cheesecloth, into the sterile beaker.
