Auricularia cornea has become one of the most important cultivated mushrooms worldwide. Although not remarkably flavorful, Auricularia species are very versatile and rehydrate easily after drying, adding a unique and pleasing texture to the dishes. In this study, we collected, identified, and domesticated a wild strain of A. cornea from the Brazilian Atlantic Rainforest. The wild strain was evaluated for mycelial growth at different temperatures and substrates, biological efficiency, and nutritional composition. The temperature that best favored the A. cornea mycelium growth was 30 °C, and the substrate was sterile Eucalyptus sawdust. The highest biological efficiency value obtained was 106.90 ± 13.28%. Nutritional analysis showed that the produced wood ears contained 71.02% carbohydrates, 19.63% crude fiber, 11.59% crude protein, 10.19% crude fat, and 4.24% ash on dry matter basis. For the mineral content profile, the elements K and P were the most abundant. This is the first report on cultivation of a wild strain of A. cornea from Brazil.
银耳已成为全球最重要的栽培蘑菇之一。虽然银耳的味道并不十分浓郁，但它的品种非常多样，在干燥后易于复水，为菜肴增添了独特而令人愉悦的口感。在这项研究中，我们从巴西大西洋雨林中采集、鉴定并驯化了一种野生银耳菌株。我们评估了该野生菌株在不同温度和基质下的菌丝生长、生物效率和营养成分。银耳菌丝生长的最佳温度为 30°C，最适宜的基质是无菌的桉树锯末。获得的最高生物效率值为 106.90±13.28%。营养分析表明，所产银耳中碳水化合物含量为 71.02%，粗纤维含量为 19.63%，粗蛋白含量为 11.59%，粗脂肪含量为 10.19%，灰分含量为 4.24%（均以干物质为基础）。就矿物质含量谱而言，元素 K 和 P 最为丰富。这是首次报道从巴西栽培野生银耳菌株。
