General MYAG with antibacterial properties

This is a premium product revolutionising mushroom cultivation.
MYAG is a gelatinous medium that is used to purify, germinate, isolate and manipulate mushroom mycelium to reduce the chances of contamination drastically due to its antibacterial compound.


Why use  MYAG instead of just MYA?

Most of the spores obtained, whether from wild, homegrown,  or trustable spore sellers, Might include bacterial contamination. That is due to methods of spore collection, preservation and transportation (Such as spore syringes and spore prints). In several cases, when spores are infected, they carry bacteria attached to them and introduce them to the Agar media. This will result in fast-growing bacterial spores that make it difficult for mushroom spores to germinate (as they are slower than bacterial spores).

On the other hand, when infected spores are introduced to MYGA (with antibacterial properties), the mushroom spores will germinate and grow, leaving behind bacterial contamination. That is because the cells composing the mycelium (Hyphae) have long and sharp filaments, which carry reduced populations (if any) of bacteria when they pass through the antibacterial properties. This antibacterial powder is an antibiotic commonly used to treat bacterial infections. In Agar mycelium cultures, it has been demonstrated to inhibit bacteria to a confinable level.


The uses of MYAG with antibacterial properties include

  • Germinating spores from a spore syringe or spore print has a likelihood of contamination.
  • Purify mycelium from other contaminated agar plates
  • Clone wild mushroom tissue, which has a likelihood of contamination

Do not have a pressure cooker? No problem; message us, and we will send you detailed instructions on how to use a microwave for sterilising along with your purchase. Please check our listing Make Agar Plates and see what you need
First, you would need a Reagent Bottle  If made in a Microwave, a 500ml reagent bottle would fit. If using a Steriliser, then a 1000ml reagent bottle should fit.

We have relied on this Mix to experiment at our lab using different varieties.
