| − | |Introduction=In this tutorial, we are going to learn how to use a mycelium syringe in liquid culture. One of the prerequisites is therefore to have a syringe of liquid culture of the mushroom variety of your choice. It is possible to provide it on the link [https://breizh-bell.bzh/produit/syringue/ following].

| − | '''Introduction to the mushroom cycle'''
| |
| − | | |
| − | What is commonly called "mushroom" is in fact only the temporary and visible "fruiting body": the [https://fr.wikipedia.org/wiki/Sporophore sporophore] (formerly called "carpophore").
| |
| − | | |
| − | It is the result of an organism with a more durable and more discreet character, formed of filaments generally invisible to the naked eye when they are isolated: the [https://fr.wikipedia.org/wiki/Myc%C3% A9lium mycelium.]
| |
| − | | |
| − | The sporophore is often in the form of a [https://fr.wikipedia.org/wiki/Stipe_(mushroom) foot] wearing a [https://fr.wikipedia.org/wiki/Hat_(mushroom) hat] .
| |
| − | | |
| − | To cultivate a mushroom, we try to reproduce the natural external conditions. Mushroom cultivation is divided into three main stages.
| |
| − | | |
| − | #Inoculation: addition of mycelium (in the form of spores or in liquid or agar culture) in the substrate
| |
| − | #Incubation: the mycelium propagates in the substrate
| |
| − | #Fructification: the mycelium wants to reproduce by forming a sporophore
| |
| − | | |
| − | '''Liquid inoculation?'''
| |
| − | | |
| − | In myciculture, inoculation by liquid culture consists of injecting mycelium contained in sterilized sugar water onto a substrate.
| |
| − | | |
| − | '''Why is it awesome?'''
| |
| − | | |
| − | There are several ways to start a mushroom crop. Liquid inoculation is one of the easiest because you just need to spray a substrate with a liquid culture. In addition, the risk of contamination is less than with other methods.
| |
| − | | |
| − | '''Receiving the liquid inoculation syringe'''
| |
| − | | |
| − | Upon receipt of the syringe containing the mycelium, place it immediately in the refrigerator, it must be used within two weeks!
| |
| − | | |
| − | You have two choices :
| |
| − | | |
| − | #Liquid culture copy: The goal is to copy the liquid culture to achieve even more culture! The liquid culture copy is <u>optional</u>!
| |
| − | #Grain inoculation: This consists of depositing a liquid culture on a substrate. Seed inoculation can be done in a jar or in a bag
| |
| − | | |
| − | {{Info|When copying liquid culture, you can only make this copy once. The mycelium weakens with the copies and your crops will not produce correctly.}}
