甜菜糖蜜酒精废液生产菌体蛋白饲料初探

Exploring in Production of Mycelium Protein Feedstuff from Beet Alcohol Wastewater

甜菜糖蜜酒精废液含有大量的有机物 ,p H值低 ,BOD、COD值高 ,直接排放会造成环境的严重污染 ,又损失了一些有机物 .在此废液中可直接接入酵母菌 ,使其大量繁殖 ,生产出的菌体粗蛋白含量达 41 .7% ,COD值降低了 2 0 %以上 ,减轻了环境污染 .

Fermentation of producing mycelium protein feetstuff from beet alcohol wastewater was studied in this article. The mycelium could grow and produce protein in the wastewater without added supplementary nutrient. Because in this culture condition, it was as much the mycelium in this wastewater as in the wastewater added supplementary nutrient, and the crude protein content was almost same. The crude protein content of mycelium was 41.7% through production. COD was reduced more than 20%.
