Mushroom Liquid Culture Pre Mix

This liquid culture pre-mix is the same mix I use for my own mushroom liquid cultures. It contains 1 gram of light malt extract and a half gram of bacteriological peptone. This is the best liquid culture recipe I have ever used and I’m excited to offer it.

Use a quart jar with a modified lid and add 500-600 milliliters of room temp distilled water. Dump the Pre-mix into the jar and stir the ingredients until they are completely dissolved and then pressure sterilize at 15 psi for 20 minutes.

Avoid using hot water to stir the ingredients as this will create sediment. You want the solution to be fairly clear with a tinge of golden color.

Keep out of sunlight and in a dry place. Use within 12 months of receiving.
