Mushroom cultivation has become an important component of agriculture, providing food and contributing to the global economy. It uses vertical space and addresses issues of food quality, health improvement, and environmental sustainability. Auricularia mushrooms are popular ingredients in traditional Chinese cuisine. The objective of this study was to determine yield and evaluate radical scavenging capacity of A. polytricha cultivated on rubberwood sawdust on a large scale; we measured total phenolic content; DPPH, hydroxyl, superoxide anion, and peroxyl radical scavenging; and reducing power. Cultivation on rubberwood sawdust produces an average of 4 harvests per bag and a biological efficiency of 80-82%. The antioxidant capacity investigations revealed that the ethyl acetate fraction was the most potent radical scavenger in all assays except that for superoxide anions, whereas the aqueous fraction exhibited mild to moderate antioxidant capacity in scavenging the various radicals. Artificial cultivation of A. polytricha on rubberwood sawdust yields many sporophores with potent antioxidant capacity.
蘑菇栽培已成为农业的一个重要组成部分，提供食物并为全球经济做出贡献。它利用垂直空间，并解决了食品质量、健康改善和环境可持续性等问题。木耳是中国传统菜肴中的常见食材。本研究的目的是大规模测定在橡胶木锯末上栽培的毛木耳的产量，并评估其自由基清除能力；我们测量了总酚含量、DPPH、羟基、超氧阴离子和过氧自由基清除能力以及还原能力。在橡胶木锯末上栽培，每袋平均可收获4次，生物学效率为80-82%。抗氧化能力研究表明，除超氧阴离子外，乙酸乙酯部分在所有测定中都是最有效的自由基清除剂，而水相部分在清除各种自由基方面表现出轻度至中度的抗氧化能力。在橡胶木锯末上人工栽培毛木耳可收获许多具有强大抗氧化能力的子实体。
