Koji - Yellow Mushroom Plate Culture

Koji - Yellow (Aspergillus oryzae) Mushroom Plate Culture.

Each culture plate is a 100x15mm petri dish inoculated with fresh Koji - Yellow (Aspergillus oryzae) mycelium growing on malt extract agar (MEA), and will arrive actively colonizing.

Koji - Yellow Mushroom Plate Culture Lab Notes

At Out-Grow's mycology lab, we have observed the following traits of this mushroom plate culture:

Koji Yellow (Aspergillus oryzae) mycelium appears white to yellowish on culture media, cottony and filamentous in early growth before developing heavy sporulation that gives colonies a powdery appearance. Growth is very fast, typically colonizing a 100mm plate in approximately 2-4 days at an optimal temperature of 82–86°F. Note: this species sporulates heavily and quickly — subculture early from the hyphal edge before heavy sporulation begins if working with mycelial-phase cultures.

Mushroom Plate Culture Use

Mushroom plate cultures, typically on MEA culture plates, are used to grow and preserve mycelium. In most cases, sterile transfers of agar wedges from this plate are used to inoculate fresh culture media or sterilized grain spawn.

Mushroom Plate Culture Storage

Your mushroom plate culture can be wrapped in parafilm and stored at normal room temps, in a sealed baggie, for up to 6 months. Out-Grow recommends you replate your mushroom plate culture every 6 months to ensure longevity of your purchase.

Store fully colonized plates at 35–43°F in darkness, sealed. Plate shelf life is approximately 2-4 months, but long-term maintenance is best done on slants or in cryostorage given this culture's importance.

Mushroom Plate Cultures Are Made to Order

All mushroom culture plates are made to order. Once your order is received, Out-Grow will inoculate your plate within 1-3 days. Your mushroom plate culture will then be incubated in our mycology lab for approximately 7-14 days, or until clean healthy mycelium has been verified by our mycologist. Once verified, your order will be shipped promptly. Please allow an additional week for your mushroom plate culture to fully colonize upon arrival, as colonization time varies by species.
