摘要
以汽爆玉米秸秆为原料 ,进行固态发酵生产蛋白饲料的研究 ,优化了发酵的工艺条件。实验结果表明 :发酵温度为 37℃ ,固液比为 1∶3,培养基中 (NH4 ) 2 SO4 的添加量为 4.5 % ,经过 4d发酵 ,蛋白含量为 16 .7% ,FPA酶活为9.5U/g .min ,失重率为 2 7%。汽爆秸秆发酵结果好于未处理的秸秆。
The study of producing protein feed with the corn straw crushed via “steam explosion” pretreatment and fermenled in a soid state optimized the technological conditions. The results showed that the fermentation effects of the steam explosion pretreated corn straw were better than that of the same material untreated. The protein contents of the feed were 16.7%,enzyme activity of FPA was 9.5 U/g.min and the weightlessness rate was 27% after 4 days fermentation under the conditions of 37℃ temperature, solid and liquid of 1∶3 and 4.5% (NH 4) 2SO 4.
