| 摘 要： | 以木薯生产中产生的废渣为主要原料,以黑曲霉、绿色木霉和根霉R2为发酵菌种,优化木薯渣发酵生产菌体蛋白饲料的工艺。初步确定了木薯渣发酵的适宜条件,即液体菌种添加量为3%,氮源添加量为20%,发酵温度37℃,发酵时间为4 d,经试验验证,此发酵条件下发酵饲料中粗蛋白含量较高,可达到蛋白饲料对蛋白质含量的要求。通过处理木薯渣变为动物的饲料原料,不仅可充分利用淀粉工业的废弃物,有利于环境保护,而且可显著降低饲养成本,从而提高了木薯渣的利用价值和经济效益。

| Abstract: | Using cassava slag as the main raw material,with aspergillus,trichoderma viride and rhizopus R2 for fermentation strains,the test is to optimize cassava slag fermentation technology producing tropina feed.The appropriate conditions of cassava slag fermentation are that adding amount of liquid spawn is 3%,adding amount of nitrogen source is 10%,fermentation temperature is 37 ℃,fermentation time is 4 days.Cassava slag is a mixture,its highest level of non-nitrogen compounds is 78.7%,main component is soluble starch compounds(such as monosaccharide and starch),but its crude protein content is very low,amino acid composition is extremely uneven,it has poor effect to feed cassava slag directly,so most of the cassava slag cannot be used,which not only causes the waste of resources,but also seriously pollutes environment.Processing cassava slag into feed materials can make full use of the waste in starch industry,it is favorable to the environment protection,and it also can significantly reduce the cost of feed,improve the utilization value and economic benefits of cassava slag. |
