1090 results about "Mycelium" patented technology

Mycelium is the vegetative part of a fungus or fungus-like bacterial colony, consisting of a mass of branching, thread-like hyphae. The mass of hyphae is sometimes called shiro, especially within the fairy ring fungi. Fungal colonies composed of mycelium are found in and on soil and many other substrates. A typical single spore germinates into a homokaryotic mycelium, which cannot reproduce sexually; when two compatible homokaryotic mycelia join and form a dikaryotic mycelium, that mycelium may form fruiting bodies such as mushrooms. A mycelium may be minute, forming a colony that is too small to see, or may grow to span thousands of acres as in Armillaria ostoyae.

The preparation method of the food-grade glassine paper is as follows: Step 1: Preparation of the base paper of edible mushroom liquid fermentation mycelium; Step 2: Preparation of the surface paper of edible mushroom liquid fermentation mycelium; Step 3: Preparation of the food-grade glassine paper. The present invention prepares the food-grade glassine paper from edible mushroom liquid fermentation mycelium, which can replace the traditional papermaking method mainly using wood as the raw material, without adding plastics and chemical coating agents, and has the advantages of environmental protection, low carbon and degradability. It is a food-grade oil-proof, moisture-proof and semi-transparent glassine paper, and has broad application prospects in various fields such as food, medicine and express labels.
