| 摘要: |
| 采用经试验所筛选出的菌种组合，就4种无机氮源和作为辅料的12种农产品加工中的副产品或废弃物，对苹果渣发酵生产词料蛋白的影响进行了试验研究，并确定了苹果渣发酵生产饲料蛋白的配方。试验结果表明，在苹果渣发酵中，可混合使用尿素和硫酸控作为无机氮源，添加量为尿素1、5％，硫酸铵2％。所选12种农产品加工副产品或废弃物均可作为辅料使苹果渣发酵生产饲料蛋白，所得发酵产物粗蛋白提高率均较显著，但选择麸皮与豆饼、菜籽饼、棉籽饼、啤酒糟等配合使用更为合适。 |

| Abstract: |
| On the basis of the stains combination acquired by screening experiment, the experiment of effect on the fermentation of pomace into feeding protein was carried out through among 4 inorganic nitrogen sounces and 12 byproducts or wastes from processing of agricultural products. The results showed that carbamide and ammonium sulfate were suitable to be used together as nitrogen source, the amount of carbamide and ammonium sulfate is 1. 5% and 2% respectively. 12 kinds of byproducts or wastes from processing of agricultural products can all be used as a complement for pomace fermentation as the increasing rates of protein of their fermented products were all quite high. Among them, bean cake, rapeseed cake, cottonseed cake and spent brewer's grain were more suitable. |
