Pre-poured petri dishes Malt Extract Yeast Peptone Agar (MYPA) for mushroom growing
Our agar plates are thick-poured, which helps to retain moisture for longer, avoiding the plates from getting dry, making your cultures last longer.
Your purchase includes
– 10x 90mm Petri dish with MYPA sealed snugly
– 10x Parafilm pre-cut strip
These plates are to be stored at room temperature. Do not store them in the fridge unless colonized.
Plate Shelf Life and Storage
The optimal shelf life for plates is 30-45 days. Order plates as needed, as they cannot be stored indefinitely, even in their original packaging. While most plates can last for months, their ideal shelf life is 30 days.
Usage and Contamination
Plates may remain usable beyond 30 days if uncontaminated. If contamination occurs in one plate, it doesn’t affect others in the pack. Discard contaminated plates and use the rest as normal.
The presence of a bubble or condensation in any of the plates is not a cause for concern.
Long-term Storage
Extended storage may cause plates to lose moisture, becoming stiff and papery. Use plates only if they remain gelatinous and uncontaminated. Discard any that become stiff or papery, as they can no longer support organism growth.
Refund Policy
For damaged or contaminated plates upon delivery:
• Contact us within 30 days of the ORDER date
• Provide photos for refund requests
• No replacements are offered; only refunds
Storage Guidelines
Before inoculation:
• Store in a cool, dry place (e.g., cupboard)
• Avoid refrigeration to prevent condensation
• Place upside down to minimize condensation
After colonization:
• Refrigerate when at least 60% colonized
• Label (date and species) and put in zip-lock bags for storage
• It is best to keep it in the vegetable compartment of the fridge
Remember: The packaging sleeve is not a sterile seal. Proper storage is crucial for maintaining plate quality.
About the petri dish-
These dishes are made of clear polystyrene, which allows for clarity while being disposable and durable. It is easy to stock and grip and has an anti-slip ring that offers stability.
Malt Extract Yeast Agar Peptone (MYPA)
What is MYPA?
MYPA Mix is the most nutritious gelatinous media to cultivate, isolate, and manipulate fungi. That is due to Peptone, which is derivative from soybeans and beef bone that supports vigorous mycelium growth and demonstrates the most efficient media for long-term maintenance of mushroom cultures (more than a year). The uses of MYPA include:
Why use Malt Extract Agar Yeast Peptone 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, which are 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).
Peptone
Mycological peptone is a mixture of peptones derived from soybean plants and animals. It is commonly used in liquid culture recipes and agar recipes and also added to substrate as a supplement.
Supplementation with Peptone not only stimulates the growth of mycelium but also greatly improves the quality of the projected Mycelium Mat.
We also offer a variety of other Pre-Poured Agar Plates and Agar Mixes to make your own agar plates. Please check them out.

Important
Please be advised that during the months of December through February, shipping agar plates can be particularly challenging due to environmental factors. When the temperature of the package exceeds 40°C, the plastic wrap or wax parafilm used for sealing may melt, shrink, or otherwise be compromised due to heat. This can increase the likelihood of contamination.
A bubble or condensation on any of the plates is not a cause for concern and does not affect the product’s quality.
If you encounter contamination, please send us a clear photo of the affected plates, along with the number of plates affected and your order number. A refund will be issued upon verification of the issue.
Please note that we are unable to offer replacements, as the same environmental conditions may lead to similar issues. We appreciate your understanding and cooperation during this period.
