【摘要】 通過正交試驗(yàn)確定了白背毛木耳(Auricularia polytricha)43-26液體發(fā)酵培養(yǎng)基的最優(yōu)配方(g/L):土豆20、玉米粉20、蛋白胨10和磷酸二氫鉀5;利用超聲波輔助水提醇沉法提取胞內(nèi)粗多糖,多糖含量為75.5%;多糖粗提物經(jīng)DEAE-52纖維素離子交換層析和Sephadex G-200層析分離純化,分別得到4個(gè)相對均一的純多糖組分AP1、AP2、AP3和AP4。
【Abstract】 A growth medium for maximizing polysaccharide production by submerged cultures of Auricularia polytricha 43-26,consisting of(g/L) 20.0 potato,20.0 corn powder,10.0 peptone and 5.0 KH2PO4,was derived by orthogonal testing.A crude fraction containing 75.5% polysaccharide was obtained by aqueous extraction of ultrasound-treated fungal mycelium and precipitation with ethanol.Crude polysaccharide was separated into four partially purified fractions,AP1,AP2,AP3 and AP4,by DEAE-cellulose 52 and Sephade...
