【中文摘要】 以液體深層培養(yǎng)的食用菌新鮮菌絲體為原料 ,使用均勻正交設(shè)計的實驗方法 ,優(yōu)化了食用菌多糖提取最佳工藝。實驗結(jié)果表明 :在鮮菌絲密度為 10 0～ 2 5 0mg/ml范圍內(nèi)、超聲波破壁時間為 12min、熱水浸提時間為 4h、提取溫度為 70℃時 ,鮮多糖提得率為 2 6 0 9%。

【英文摘要】 The optimization study of polysaccharide extraction from fresh mycelia of edible fungi prepared by liquid submerged-culture were studied.The results were as follows:when the density of mycelia were at the range of 100～250 mg/ml(wet weight),the time of ultrasonic treatment were 12 min,and the extracting time were 4h at 70℃ the extraction rate of polysaccharide were 2.609%(wet weight)
