【中文摘要】 通過優化培養基組成,提高雞腿菇發酵液對非酶糖基化反應的抑制活性。試驗以抑制非酶糖基化反應活性為指標,通過單因素試驗篩選了適宜碳源、氮源、無機鹽以及復合營養因子,通過正交試驗進一步優化培養基組成。試驗結果表明,使用優化培養基[麥芽糖4%,牛肉膏0.6%,黃豆芽(煮汁)200 g/L,洋蔥(煮汁)100 g/L,MgSO40.12%,FeSO40.10%,CuSO40.03%,ZnSO40.05%]液體培養雞腿菇,其發酵液對非酶糖基化反應的抑制率高達97.32%。
【英文摘要】 A culture medium for Coprinus comatus has been designed whereby the non-enzymatic glycation-inhibiting activity of the fermentation broth was maximized.Different carbon and nitrogen sources,inorganic salts and natural components were screened initially using single factor experiments,followed by orthogonal tests designed on the basis of the data obtained.The highest inhibition rate(97.32%) was achieved using a culture medium composed of maltose 4%,beef extract 0.6%,soybean sprout juice 200 g/L,onion juice 100 g/L,magnesium sulfate 0.12%,ferrous sulfate 0.1%,copper sulfate 0.03% and zinc sulfate 0.05%.
