Agar Mix MYA Malt Extract Yeast Agar

Malt Extract Yeast Agar (MYA)

What is MYA?

Malt Extract Agar Mix is a gelatinous medium widely used to cultivate, isolate and manipulate fungi, yeast, and moulds. It is also a method of long-term maintenance of mushroom cultures. The uses of MYA include:

• Germinating spores
• Isolating a specific strain of mushroom
• Growing mushroom mycelium for expansion into grain spawn
• Determining if a liquid culture is contaminated
• Long term storage

Why use Malt Extract Agar Yeast for growing mushroom culture?

Malt Extract

Malt extract contains a high concentration of maltose, which provides a suitable environment for the growth of yeast and mold. That is due to its rich source of carbon, protein, and nitrogenous compounds used as energy for fungi growth.

Agar-Agar

Agar-Agar is extracted from various seaweeds, such as gracilaria and gelidium (It contains no animal ingredients. Due to Agar’s unique gel property and stability, it is used as a firming and thickening agent for Petri dish experimentation.)

Yeast (S. Cerevisiae)

The strain species S. Cerevisiae is grown on sugar beet molasses, making it a natural source of readily assimilated amino acids and proteins. For mushrooms, this means a rich supplemented diet of dietary fiber, Vitamin D, and B Complex (Thiamine, Riboflavin, Niacin, Pantothenic Acid, Folic Acid, Biotin, Vitamin B6, and Vitamin B12).

*Please note that MYA is different from MEA. MYA includes Yeast, whilst MEA is Malt Extract and Agar only.*

Quantity specifications:

These quantities are measured based on 60*15mm size Petri dishes:

The number of plates made will vary according to pouring techniques; we recommend using just enough to cover the surface of the petri dish.

• 21 gm makes 35 Agar Plates   (Use 500ml of hot water)
• 42 gm makes 70 Agar Plates   (Use 1000ml of hot water)
• 63 gm makes 105 Agar Plates (Use 1500ml of hot water)
• 84 gm makes 140 Agar Plates (Use 2000ml of hot water)
• 168gm makes 280 Agar Plates (Use 4000ml of hot water)

*Petri dish is not included.

Instructions

1. Dissolve your MYA packet in the specified ratio of hot water (i.e.1000 ml water for 42 gm of MYA) and stir thoroughly with a spoon. If you have a magnetic stirrer, this will mix the solution properly. The content needs to be poured slowly and not all at once.
2. Autoclave or pressure cook for 20 minutes at 15 psi.
3. Pour into Petri dishes when it reaches 50 degrees Celsius (Approximately hot enough to hold the flask/ jar with one hand), and let it set for 10 minutes. Do not stir the solution after taking it out of Autoclave, as this would lead to air bubbles being trapped in this solution.
4. Once the Petri dishes are set, inoculate them and wrap them with parafilm. Keeping the plates aside for a week is recommended to check for contamination.
5. Petri dishes are best to be stored upside down to avoid condensation.

Do not have a pressure cooker? No problem; You can also Microwave Sterilize your own container or jars jars. 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 Sterilizer, then a 1000ml reagent bottle should fit.

We have relied on this Mix to experiment with different varieties in our lab.
