摘要
采用厌氧发酵法对马铃薯淀粉深加工薯渣废料进行厌氧发酵,试验设置3个处理,分别添加或不添加米糠、尿素、过磷酸钙,供给微生物发酵过程所需的碳源、氮源、磷源以及无机盐。通过对厌氧发酵产物成分的测定得出:马铃薯淀粉深加工薯渣废料经厌氧发酵后粗蛋白和蛋白质氮的含量分别提高182.78%和68.18%,总酸提高307.05%,乳酸含量提高2646.19%。发酵产物可做粗饲料使用。
Anaerobic fermentation is carried into the potato processing residue in the fermented method aversion to oxygen.The experiment has three treatments,respectively,with or without rice bran,urea,calcium superphosphate,providing micro-organism with carbon,nitrogen,phosphorus and inorganic salt in the process of fermentation.Through the determination of？anaerobic fermentation products,the content of crude protein grows by 182.78%,protein nitrogen grows by 68.18%,the total acid grows by 307.05% and lactic acid grows by 2646.19%.The？fermentation products can be used as roughage.
