| 摘 要： | 通过单因素试验,研究了不同液体发酵条件对猪苓多糖提取量的影响。研究结果表明:接种量、培养温度、振荡器转速、培养天数、培养基碳源、氮源及金属盐类等因素对猪苓多糖的提取量均有影响;当接种量为3片菌丝、培养温度为25℃、转速为150 r/min、培养15 d、培养基碳源为葡萄糖、氮源为蛋白胨、金属盐类为KH2PO4时,猪苓菌丝生长最好,猪苓多糖的提取量最高,达0.093~0.121 g。

| Abstract: | This article studied the effects of different conditions on the extraction of polysaccharide from grifola by liquid fer -mentation through single -factor experiments .The results showed that inoculum size , culture temperature , rotate speed of oscillator , culture duration , as well as carbon source , nitrogen source and metal salt in medium all had effects on the extraction of polysaccha -ride from grifola.When 3 pieces of mycelia were inoculated and cultured for 15 days at 25℃, the rotate speed was 150 r/min, and the medium contained glucose , peptone and KH 2 PO4 , the mycelia of grifola grew best , and the extraction quantity of grifola polysac-charide was the highest , reaching 0.093-0.121 g. |
