桑黄胞外多糖生产培养基的初步研究

Primary research on culture medium of generating extracellular polysaccharide of phellinus igniarius

进行桑黄菌SA-1深层培养产胞外多糖培养基的初步研究,对桑黄菌SA-1进行了不同碳、氮源及碳、氮源含量组合的试验,测定和比较了菌丝和多糖产量。最佳碳、氮源分别为玉米淀粉、蛋白胨+酵母粉,其含量分别为4.5%、0.5%。

To study the culture medium of generating extracellular polysaccharide of Phellinus igniarius. The different element of C、N and contents were compared by mensurating the output of mycelium and polysaccharide. The suitable element of C、N are corn amylum and peptone+yeast extract, which content are 4.5% and 0.5%.
