Safety Precautions When Handling Laboratory Grade Mushroom Spores

Safety Precautions When Handling Laboratory Grade Mushroom Spores

where do mushroom spores come from

Have you ever questioned where do mushroom spores come from? There is an entire science behind handling laboratory grade mushroom spores, to prevent contamination that will ruin the culture.

The first vital step is to prepare the fungus substrate. Bulk substrates are different when it comes to density, composition, chemical profiles, microbial loads etc. Each substrate contains a certain amount of competing organisms that must be eliminated; otherwise they will attach your mushroom spores, competing for the food.

So, any mushroom laboratory needs a detailed substrate preparation procedure, including protocols for various substrates, and must have proper sterilization equipment (self-contained research-grade laboratory autoclave)

Mushroom spores must be injected into a substrate that has been sterilized. Some mushroom growers also talk about pasteurization instead of sterilization of the substrate, but pasteurization is not so effective, as it only weakens microorganisms.

Research-grade lab autoclaves will sterilize the substrate in 15-45 minutes, depending on volume.

Additional safety precautions include properly venting the autoclaves outside of the building and directly to the sanitary sewer, as operations such as freesteaming or vacuum options produce waste water and steam.

Although some mushroom growers “recycle” the steam, this practice is not recommended, as it might disperse the spores all over your lab.

What Do Native Americans Know About the Healing Properties of Magic Mushrooms?

Image
Magic mushrooms aren’t anything new. They have been around for centuries and have been used by various civilizations worldwide. For instance, archeological evidence suggests that the Native Americans used magic mushrooms in ritualistic ceremonies. That’s because magic mushrooms can alter the state of mind of a person and induce a trance-like state. This is what some researchers say Native Americans used to communicate with the spirit world or be able to commune with other entities. So, Native Americans figured out that magic mushrooms, such as highly potent Penis Envy mushrooms , can lead to an altered state of mind. But they might have even gone further than that. Magic mushrooms are used today in small doses to treat various diseases and disorders. For instance, stress and anxiety can be treated with these mushrooms. Although the Native Americans might not have called them that, they might have experienced such disorders. And they might also have figured out that magic mushrooms...

Evaluating Mushroom Spore Syringes – Quality and Concentration Differences

Image
Mushroom spore syringes are seen as a popular choice for those looking to cultivate mushrooms in the comfort of their own home. However, not all spore syringes are built the same. There are significant differences in quality and spore concentration that can impact the success of your mushroom growing efforts. One important factor to take into account is the source of the spores. Keep in mind that the best place to buy mushroom spores from top suppliers that use high-quality, pure spores that have been properly sterilized and stored. Poor quality spores may contain contaminants or be old or less viable, which often leads to failed growth cycles. The concentration of mushroom spores in mushroom spore syringes can vary depending on the specific type of mushroom being cultivated and the method used to create the spore syringe. Spore syringes are made by suspending a large number of spores in a sterile liquid solution, such as water or nutrient broth. The specific concentration of spores...

Why Laboratory Grade Mushrooms are the Best Choice for Quality and Consistency

Image
As their name suggests, lab-grade Golden Teachers mushrooms , and other types as well, are particular spores, usually stored in syringe spores or spore prints, grown in specialized laboratories. They are used for scientific research because the mushrooms they come from are illegal and cannot be sold or purchased. But spores can be studied legally, which is currently very important for research. To obtain them, certain conditions must be met. The laboratory must be equipped with a sterile room where inoculation occurs. The lab is a sterile room with HEPA filters. Then there is the incubation room, which houses the sawdust bags and the spawn if that is the method of choice for growing mushrooms. The microscope media room is another essential part of the facility. There are also pasteurization rooms, cold rooms, shipping/receiving rooms, and production or collection rooms. It is very convenient to have separate rooms for the inoculation and seeding stages of the growth process, to keep...
