Auricularia spp. is an important edible and medicinal mushroom that is widely cultivated in Asia. In previous studies identified that Auricularia spp. has the major active compounds, with many biological functions, including anticoagulant, antitumor, antiobesity, and immune activities. As a result of analysis of the components of the Auricularia spp. extract, 11 types of substances with a content higher than 1% were found. The content of ergosterol was 39.7%, showing the highest content among them. Ergosterol is a sterol found in cell membranes of fungi and protozoa, serving many of the same functions that cholesterol serves in animal cells. It is also used as a target for antifungal and antiprotozoal agents, and is also a precursor to vitamin D2. Vitamin D is known to be important for maintaining bone and health because it causes osteoporosis and is related to heart disease, obesity, and diabetes. Therefore, a study was conducted to select a strain with a high ergosterol content of wood ear mushroom. As a result of analyzing the ergosterol content, KNR11047, KNR11002, and KNR11025 strains showed high levels in fruiting bodies, and KNR11035 and KNR11022 strains showed high levels in mycelium. It was confirmed that the strain that can obtain the most ergosterol per bottle was KNR11032 for the fruiting body and KNR11035 for the mycelium.
