Beschreibung
Zusammenfassung:	The invention relates to the technical field of biological fermentation, in particular to a fermentation medium for improving black fungus melanin yield and application thereof. According to the fermentation culture medium provided by the invention, the yield of melanin in the black fungus fermentation liquid can be remarkably increased by 22.3% compared with that of a PDA culture medium through compounding of proper components at proper concentration, the melanin has the advantages of relatively high in-vitro antioxidant activity and the like, a melanin solution has relatively high scavenging capacity on DPPH free radicals, OH free radicals and ABTS free radicals, and IC50 is 3.82 mg/mL, 2.06 mg/mL and 144.20 mg/mL respectively. 本发明涉及生物发酵技术领域，特别是涉及一种提高黑木耳黑色素得率的发酵培养基及其应用。本发明提供的发酵培养基通过适宜的组分在适宜浓度下复配，可以显著提高黑木耳发酵液中黑色素得率，较PDA培养基提高了22.3％，并且黑色素具有较强的体外抗氧化活性等优点，黑色素溶液对DPPH自由基、OH自由基和ABTS自由基清除能力均较强，IC50分别为3.82mg/mL、2.06mg/mL和144.20mg/mL。
