为考察纳豆芽孢杆菌发酵固体麸皮生产绿色保健饲料,实验以纳豆芽孢杆菌为发酵菌株,麸皮为原料,羟自由基清除率为衡量指标,通过单因素和正交实验对发酵条件进行优化,确定了在250 ml锥形瓶中的最佳发酵工艺条件:麸皮10 g、初始pH7.0、接种量6%、初始含水量60%、温度32℃、发酵时间48 h,在该优化条件下,纳豆芽孢杆菌发酵麸皮的羟自由基清除活性最高。
為攷察納豆芽孢桿菌髮酵固體麩皮生產綠色保健飼料,實驗以納豆芽孢桿菌為髮酵菌株,麩皮為原料,羥自由基清除率為衡量指標,通過單因素和正交實驗對髮酵條件進行優化,確定瞭在250 ml錐形瓶中的最佳髮酵工藝條件:麩皮10 g、初始pH7.0、接種量6%、初始含水量60%、溫度32℃、髮酵時間48 h,在該優化條件下,納豆芽孢桿菌髮酵麩皮的羥自由基清除活性最高。

In order to investigate the bacillus natto fermented solid wheat bran to product green feed,using bacillus natto strains for fermentation,wheat bran as raw material,the scavenging capacity of ·OH as indicators,the fermentation conditions in 250 ml beakerflask were optimized through the single factor and orthogonal tests.The results showed that:wheat bran 10 g, initial pH7.0,the inoculum size 6%,initial water content 60%,at 32℃for 48 h,the scavenging capacity of ·OH was very high.
