Guide on How to Store Mycelium Properly

Understanding Mycelium

What is mycelium?

You may be surprised to know that the most significant part of a fungus is usually hidden beneath the surface. This critical component called mycelium, is an intricate, thread-like network of cells. Given its delicate nature and predominantly subterranean existence, mycelium is typically invisible to the naked eye yet plays a crucial role in the ecosystem by decomposing organic matter and helping with nutrient cycling. Its potential uses span industries from textiles and construction to medicine and environmental rehabilitation.

Why is proper mycelium storage necessary?

Just like any other biological material, mycelium requires specific conditions to maintain its viability and prevent contamination. Proper storage of mycelium is crucial for several reasons. First, it ensures the preservation of the genetic material of the fungus which may be needed for future cultivation. Second, it prevents the growth of competing organisms that could hinder the usefulness of the mycelium or even make it harmful. Finally, it helps maintain the biological functionality of the mycelium, ensuring it remains healthy and able to perform its unique capabilities when utilized.

Checking the Quality of Mycelium

Recognizing healthy mycelium

Healthy mycelium is typically characterized by a vibrant white or cream color with a dense, thread-like structure. It should be moist but not wet and should smell fresh, with no signs of unpleasant odors. If your mycelium is fulfilling these criteria, it is in a good state.

Avoiding contaminated or unhealthy mycelium

Contamination can be a major problem when dealing with mycelium. Unhealthy mycelium is often recognizable by visible signs of mold, such as green, black, or grey spots. Other indicators of compromised mycelium include foul odors and a sludgy or slimy texture. It’s essential to discard any contaminated mycelium to prevent the spread of pathogens and protect other mycelial samples.

Initial Preparation for Mycelium Storage

Cleaning the storage area

Before you commence with the storage process, ensuring your storage area is spotlessly clean is paramount to avoid contamination and promote the longevity of your mycelium. The area should ideally be dust and dirt-free, well-sanitized, and void of any conditions that could encourage the growth of any unwanted microbes.

Gathering necessary storage materials

Your storage materials will largely depend on the chosen preservation method. Some common supplies include sterilized containers, high-quality zip-lock bags, refrigeration or freezing units, and possibly dehydration equipment, depending on your specific needs.

Preparing the Mycelium for Storage

Proper mycelium harvest

Harvesting mycelium must be done with utmost care to prevent damaging this delicate network of fungal threads. It’s recommended to use sterilized equipment and to handle the mycelium gently, making sure not to tear or disrupt the interconnected structure excessively.

Cleaning the mycelium

Before storage, the mycelium needs to be cleaned to eliminate any remaining substrate or other debris. A soft brush can be used for this task. After cleaning, the mycelium should be carefully dried to prevent excess moisture, which could lead to spoilage during storage.

Choosing the Right Storage Conditions

Ideal temperature for mycelium storage

Although the exact storage temperature can vary slightly depending on the specific species, mycelium is generally best stored at cool temperatures, usually between 2 and 4 degrees Celsius.

Appropriate humidity level

Too much moisture can lead to the growth of mold and other contaminants, so it’s important to maintain a relatively low humidity level in your storage area. Sealed containers can help prevent excess moisture accumulation.

The importance of dark environment

Light can rapidly deteriorate the mycelium, affecting its viability. Therefore, it is crucial to store your mycelium in a dark environment.

Selecting Suitable Storage Containers

Types of storage containers

Depending on your needs, both glass and plastic containers can be used to store mycelium. Whatever the material, the container should be sterilized before use to avoid contamination.

The size of the containers

The size of the containers will largely depend on the amount of mycelium you plan to store. However, ensure the mycelium is not too packed in to prevent damage.

Proper sealing of containers

Sealing your containers correctly is important to secure the mycelium from potential contaminants and also to maintain consistent storage conditions.

Preserving Mycelium in a Refrigerator

Steps to refrigerate mycelium

When refrigerating mycelium, place your sterilized container or zip-lock bag with the mycelium into a refrigerator set to a suitable temperature. The mycelium should be checked regularly to monitor its condition.

How long can mycelium be stored in a fridge?

While the exact time can vary, as a rule of thumb, mycelium can usually be stored in a refrigerator for up to a few months with minimal loss in quality, provided all other appropriate storage conditions are met.

Precautions while storing mycelium in a refrigerator

Avoid storing mycelium near any strong-smelling food items, as these can alter the smell or even the growth pattern of the mycelium. Monitor humidity levels to prevent excess moisture, which could lead to contamination.

Freezing Mycelium for Long-Term Storage

Steps to freeze mycelium

If your aim is to store mycelium for an extended period, freezing can be an effective method. Place your mycelium in a suitable, well-sealed container or bag and put it directly into a freezer set to a temperature of zero degrees Celsius or below.

How long can mycelium be stored in a freezer?

When appropriately frozen, mycelium can be stored for several years. However, be sure to check the mycelium periodically to ensure that it remains in good condition.

Precautions while freezing mycelium

Avoid constant freeze-thaw cycles, as these can adversely impact the mycelium’s viability. Use high-quality containers or bags that are capable of withstanding freezing temperatures without cracking or breaking.

Inspecting Stored Mycelium

How often should you check on stored mycelium?

Stored mycelium should be checked at least once every few weeks or more often if possible. This check is to identify any signs of contamination or deterioration promptly.

Signs of mycelium deterioration

Watch for changes in color, texture, or smell; these could be signs of mycelium decline. Any visible mold growth is a clear sign of contamination and warrants immediate action.

Disposing of Contaminated or Expired Mycelium

Signs that mycelium should be disposed

If you notice any signs of contamination or deterioration, such as foul odors, changes in color or texture, or visible mold growth, it’s time to dispose of the mycelium.

Safe mycelium disposal procedures

When disposing of the mycelium, do so in a manner that does not risk spreading the contaminants to your other stored materials. This typically involves bagging and sealing the contaminated mycelium and then discarding it according to local regulations for biohazardous materials. Remember always to handle contaminated materials with appropriate personal protective gear.

In conclusion, mycelium storage may sound daunting, but with the correct knowledge, it is entirely manageable. The preservation of mycelium not only ensures its viability for future uses but also contributes to the crucial task of preserving our planet’s precious biodiversity.
