It´s also one of the health materials commonly used in the market. However, most of the current sources of raw materials come from crustaceans and these animal sources are not suitable for vegetarians and crustaceans, using acid and alkali to treat treatment of the environment adverse. Fortunately, edible and medicinal mushrooms not only rich in extracellular enzymes can be uesed to converse chitin to produce GlcN, and can produce a variety of physiologically active substances. In this study, production of GlcN from agricultural byproducts by using edibe and medicinal mushroom biotransformation technology was researched. During the experiment, the strain with the highest conversion efficiency was screened and the optimum transformation method was discussed. The results show that the ability to convert chitin is the highest Cordyceps militaris (CM). While GlcN production was the highest agricultural byproducts with loofah (LC). However, LC production is too low to achieve commercial production value, so the second highest yield of GlcN and with the highest yield of byproduct is corn core (CC) that would be a transformation matrix. After the last feed transformation culture of it´s final product of the physiologically active substance ergosterol and polysaccharide content to 1% fermented solid of the highest; Adenosine content is 5% solid fermented content is higher; the antioxidant properties, after the culture of the products are improved trend. Based on the above results, edible and medicinal mushrooms can be effectively utilized to generate GlcN agricultural byproducts and increase product value, but also to achieve the purpose of sustainable use of agricultural resources.
