Sterilization is key to preventing contamination
Mushroom cultivation is a process of growing fungal tissue in an environment with enough food to support its growth. In a completely sterile environment, the fungus can grow quickly as it does not encounter pests or competitors. However, it is very difficult to create a completely sterile environment as microscopic particles such as dust and spores are present almost everywhere. Therefore, sterilization is a critical step in the mushroom cultivation process to prevent contamination.
Contamination can deplete the nutrients available to mushrooms, cause them to break down and decay, and even make people ill if the mushrooms are meant for consumption. To prevent this, it is important to sterilize the substrate before inoculation. Sterilization involves heating the substrate to temperatures above 120°C under pressure to kill any living or dormant contaminants. This can be done using a pressure cooker or an autoclave, which is a standard piece of laboratory equipment.
Liquid culture is a popular method for mushroom cultivation as it simplifies the process, reduces costs, and is less prone to contamination. To create liquid culture, a sugar source such as honey or light malt extract is mixed with water, and the solution is sterilized before introducing mushroom mycelium. This can be done at home using basic ingredients and without specialized equipment. The liquid culture can then be used to inoculate grain or other substrates.
It is also important to create a sterile work area and use sterile tools during the inoculation process to prevent contamination. This includes sterilizing needles with a flame between each inoculation to prevent cross-contamination. Following these sterilization procedures is crucial to ensuring successful mushroom cultivation and preventing the growth of unwanted organisms.
