【中文摘要】 研究了營養因子對黑木耳液體發酵的影響,優化了黑木耳液體培養基的組成成分,以SD大鼠為實驗動物,研究了黑木耳液體發酵物的降血脂作用。結果表明,黑木耳液體發酵的最佳培養基組成為:5%蔗糖、5%麩皮煮汁、0.5%酵母膏、0.2%KH2PO4、0.1%MgSO4、pH自然。動物試驗結果表明,黑木耳液體發酵物能顯著降低大鼠血清中的總膽固醇、甘油三脂、高密度脂蛋白膽固醇及低密度脂蛋白膽固醇。

【英文摘要】 The effect of selected nutritional factors on the mycelium yield from submerged cultures of Auricularia auricula was evaluated.Highest mycelium yield was recorded when yeast extract and sucrose were added to the culture medium as supplementary nitrogen and carbon sources,respectively.The composition of the optimized medium(pH 6.0) was 5%(w/v) sucrose,5%(v/v) wheat bran juice,0.5%(w/v) yeast extract,0.2%(w/v) KH2PO4 and 0.1%(w/v) MgSO4.Incorporation of combined fungal mycelium and spent culture fluid into the diet significantly reduced the blood levels of total cholesterol,triglyceride,high density lipoprotein cholesterol and low density lipoprotein cholesterol in mice.
