How to make a Spore Syringe

If you’re interested in mushroom cultivation or microscopy research, one essential thing you’ll need to know is How to make a spore syringe. This tool allows you to store and distribute mushroom spores in a clean and controlled manner, ensuring successful inoculation. While purchasing spore syringes is an option, making your own can be more cost-effective and rewarding. This guide will walk you through everything you need to know about creating a spore syringe, from gathering supplies to using your finished product. Whether you’re new to mushroom cultivation or looking to refine your skills, this comprehensive guide will provide you with the knowledge you need to get started.

What is a Spore Syringe?

A spore syringe is a device used to store and distribute spores in a liquid suspension, typically water. The syringe makes it easier to introduce the spores into a growing medium, such as sterilized grain or agar. Inside the syringe, the mushroom spores are suspended in sterile water, allowing for easy inoculation of substrates or research under a microscope.

Mushroom spores are the reproductive units of fungi and contain all the genetic information necessary for the growth of a new mushroom. They are microscopic, so knowing how to make a spore syringe helps to manage these tiny spores in a sterile and easy-to-use format.

Why Make Your Own Spore Syringes?

While you can purchase spore syringes from reputable suppliers, making them yourself offers several benefits:

• Cost-Effective: You can create multiple syringes from a single spore print, allowing you to stretch your resources further.
• Customization: By creating your own syringes, you can work with specific strains of mushrooms that may not be commercially available.
• Learning Opportunity: Knowing how to make a spore syringe allows you to understand more about mushroom cultivation and how to handle spores in a sterile environment, building essential skills for more advanced mycology projects.

Materials You’ll Need

Before you begin making a spore syringe, you’ll need to gather the necessary materials. Here’s what you’ll need:

1. Spore Print or Spore Swab: The source of the mushroom spores. This is a collection of spores from the gills of a mature mushroom, stored on a sterile surface like foil or paper.
2. Sterile Syringes: Typically, 10cc or 12cc syringes are used for spore solutions. You can purchase these online or at a pharmacy.
3. Distilled Water: Sterile, distilled water is essential for suspending the spores. Avoid tap water as it may contain contaminants that could harm the spores.
4. Shot Glass or Small Container: Used for mixing the spores with water.
5. Alcohol Lamp or Butane Torch: To sterilize your tools during the process.
6. Latex or Nitrile Gloves: To maintain sterility and prevent contamination.
7. Scalpel or Knife: For handling the spore print.
8. Pressure Cooker or Steam Sterilizer: Used to sterilize water and any tools you’ll be working with. This is a tool you will using often when you know how to make a spore syringe.
9. Ziploc Bags or Aluminum Foil: For storing spore prints or for working in a sterile environment. Foil is preffered.
10. Disinfectant Spray (Isopropyl Alcohol 70%+): To sterilize the workspace. Some will say this does not sterilize but it does keep things clean. Used often when learning how to make a spore syringe.

Step-by-Step Guide to Making a Spore Syringe

Step 1: Prepare Your Workspace

Sterility is key when working with mushroom spores, so it’s essential to set up a clean environment. Choose a well-ventilated area and thoroughly disinfect your workspace. Use a spray bottle filled with isopropyl alcohol or another disinfectant to wipe down surfaces. Be sure to wear latex or nitrile gloves to avoid introducing bacteria or contaminants into your spore solution.

Step 2: Sterilize Your Water

Using sterilized water is critical when making spore syringes. Begin by pouring distilled water into a glass jar or small container. If you have a pressure cooker, place the jar in the cooker and sterilize it at 15 PSI for 20 minutes. If you don’t have a pressure cooker, you can boil the water in a pot for about 30 minutes, making sure the container is also sterilized. Let the water cool completely before moving to the next step.

Step 3: Prepare the Spore Print

To work with mushroom spores, you’ll need a spore print or spore swab. If you’re using a spore print, carefully open the foil or paper where the spores were deposited by a mature mushroom. Using a sterilized knife or scalpel, gently scrape off a small portion of the spores into a sterile shot glass or small container. A little goes a long way, so you only need a tiny amount for each syringe.

Step 4: Prepare the Syringe

Remove the cap from your sterile syringe and draw up the cooled, sterilized water. If you’re using a syringe with a sterile needle, make sure the needle doesn’t touch any unsterilized surfaces. After drawing the water into the syringe, squirt a small amount of water into the shot glass containing the spore print. Swirl the water around gently to suspend the mushroom spores in the liquid.

Step 5: Draw the Spore Solution into the Syringe

Once the spores are thoroughly mixed with the water, carefully draw the spore-filled liquid back into the syringe. Take your time to ensure the liquid is evenly suspended and that no clumps of spores remain at the bottom of the container. Depending on the amount of spore print and water used, you may be able to make several spore syringes from one print.

Step 6: Cap and Store the Syringe

After filling the syringe with the spore solution, cap the needle with the sterile cover to avoid contamination. Label the syringe with the strain of the mushroom spores and the date it was made. Store your completed spore syringes in a cool, dark place, like a refrigerator, to maintain their viability. Properly stored, spore syringes can last for several months to a year.

How to Use Your Spore Syringe

Now that you know how to make a spore syringe with your own spore syringe, you’re ready to use it for inoculation or microscopy. When you’re ready to use it:

1. Sterilize the needle by heating it with an alcohol lamp or butane torch until it glows red.
2. Allow the needle to cool for a few seconds before using it to inoculate your substrate (such as grain or agar).
3. Push a small amount of the spore solution into your substrate, distributing it evenly to ensure successful colonization.

When working in mushroom cultivation, it’s important to maintain sterile techniques throughout the entire inoculation process to prevent contamination.

Tips for Success

• Keep it sterile: Contamination is the number one reason for failed mushroom cultivation, so always use proper sterilization methods. Avoid touching any sterile surfaces, and work in a clean, disinfected environment.
• Label everything: Label your spore syringes with the date and strain, especially if you plan on making multiple syringes at once.
• Storage: Always store your spore syringes in a cool, dark place, preferably in the refrigerator. This will ensure the spores remain viable for long periods of time.
• Practice: Making your own spore syringes may seem complicated at first, but with practice, it becomes easier and more intuitive. Take your time and follow the steps closely for the best results.

Conclusion

Making a spore syringe is a rewarding and practical skill for anyone interested in mushroom cultivation or microscopy. With the right materials and proper technique, you can produce clean, viable spore syringes that will serve you well in your mycology journey. Not only does this method save you money, but it also gives you more control over the strains and quantities you work with.

Whether you’re cultivating mushrooms for personal use or conducting research, creating your own spore syringes is a valuable skill that can lead to greater success and understanding in the fascinating world of fungi.
