摘  要：
为高效利用稻谷加工副产品米糠并拟在固态发酵设备中发酵生产多糖保健食品,以米糠为基础培养基,对灰树花固态发酵米糠产多糖条件进行探索。针对定量米糠,选取水分、蛋白胨、葡萄糖和pH值影响因素,以总多糖含量为评价指标进行试验,按L16(45)的正交试验方案得到优化培养基,并进一步通过单因素试验选择得到较优的固态发酵工艺条件。结果表明:优化固态培养基组成为原始米糠(水分为65%,按原始米糠质量计)、蛋白胨0.5%、葡萄糖4%、pH5.5、装样量20g/250mL三角瓶,发酵条件为:接种量10%、培养温度25℃、摇床转速170r/min、培养时间11d,多糖得率以米糠为标准计算,可达4.52%。用SPSS软件处理数据,得到表征多糖产量和培养基成分关系的回归方程。

摘  要：
In order to effectively exploit rice bran for preparing health food containing polysaccharides through mimic solid fermentation, rice bran was used as the culture medium matrix to explore the effects of water content, peptone, glucose and pH on solid fermentation of Grifola frondosa. The optimal culture medium and fermentation conditions were explored by single factor and orthogonal experiments on the basis of grifolan productivity. Results indicated that the optimal medium formula was composed of rice bran as solid culture medium matrix with 65% water, 0.5% peptone, 4% glucose (by mass of rice bran) and pH 5.5. The optimal fermentation conditions were 20 g rice bran matrix in a 250 mL fermentation flask, inoculation amount of 10%, fermentation temperature of 25 ℃, rotation speed of 170 r/min and fermentation time of 11 days. The yield of grifolan was 4.52% under the optimal conditions. By calculating with SPSS software, a regression model of total grifolan was achieved.
