Microbial Innoculant Manufacturing
Things you need -
Peptone: Bacterialogical, 100g - About 12 USD.
Beef Extract Powder, High Purity Grade 50g - About 10 USD
Distilled Water
An Autoclave OR an Insta-Pot OR Mason Jars, a stove, and a pot of water.
Dissolve 5g peptone in 850ml of distilled water
Dissolve 3g meat extract in the solution from step 1
Adjust pH to 7.0
Bring to 1000ml with distilled water
Autoclave it. If you don't have an autoclave but you *do* have an Insta-Pot,
run it for one minute on steam. Let it heat up, and cool off the slow way. Place your sample Bacterial Innoculant into cooled but still warm broth and seal. (Under 100f)
Give it a couple days. Keep it in a warmish place.
Addendum - If you don't have an Autoclave or an Insta-Pot, you can put your fluid into a mason jar, (no lid on it) inside of a pot of boiling water, and let it heat up for a while.
If you want to get super fancy, throw half of an alfalfa pellet into your broth before heating it up.
