[0002] Shiitake mushrooms belong to the class Basidiomycetes, order Agaricales, family Tricholomataceae, and genus Lentinus. Originating in my country, they are the world's second most abundant mushroom and a renowned and precious edible fungus in my country. my country has been cultivating shiitake mushrooms for over 800 years. Shiitake mushrooms are also a famous medicinal fungus in my country, with numerous medical scholars throughout history documenting their medicinal properties and uses. Shiitake mushrooms are characterized by their thick, tender flesh, delicious flavor, unique aroma, and rich nutritional value, making them a food with both edible and medicinal properties, possessing high nutritional, medicinal, and health-promoting value. In the cultivation of shiitake mushrooms, mushroom bags are required. These bags need to be sterilized before use to prevent other bacteria on the bags from affecting the growth of the edible fungus.
