【中文摘要】 从贵州安顺分离筛选到一株鸡【 (Termitomycesalbuminosus) ,对其产胞外多糖特性进行研究后 ,用正交设计试验方法获得产胞外多糖优化液体培养基配方如下 :玉米淀粉 1.5% ,葡萄糖 1.5% ,酵母粉 0 .4 % ,蛋白胨 0 .2 % ,KH2 PO4 0 .2 % ,MgSO4 0 .0 5% ,pH4 .8,最大胞外多糖产量可达 1.75g/L。
【英文摘要】 A strain of Termitomyces albuminosus was isolated and screened out from Anshun of Guizhou province. Its exopolysaccharide producing characteristics were studied. And it was identified that the optimum liquid medium for T. albuminosus exopolysaccharide production under laboratory conditions was as follows: corn starch 1.5% , glucose 1.5%,yeast extract 0.4%,peptone 0.2%, KH 2PO 4 0.2%, MgSO 4 0.05%, pH4.8, and that the highest yield of T. albuminosus exopolysaccharide was up to 1.75g/L.
