摘要：利用固态发酵的方法对城市餐厨垃圾进行处理,制造富含菌体蛋白的饲料。研究中采用多种酵母菌和霉菌混合发酵,筛选出了(白地霉F-1,米曲霉F—6)为优势菌种组合,并考察了发酵条件,最优化结果为:对发酵培养基高温灭菌20 min,加入(NH_4)_2SO_4 1％,KH_2PO_4 4％,NaCl3％,初始pH 5.5,含水率60％左右;种子液15％,接种比例为1:1,发酵5d。最终得到的饲料粗蛋白含量为33.87％,比原料增加了6.85％。
Municipal food waste is treated with solid-state fermentation to produce feeding-protein. In this study, several yeast and mold are combined to ferment the waste; the excellent mixed strains of Geotrichum candidum F - 1 and Aspergillus oryzae F - 6 are selected. The best condition of fermen- tation is as follows: 20 minutes high temperature pretreatment, 1% (NH_4)_2SO_4, 4% KH_2PO_4, 3% NaCl, pH 5.5, 60% water content, 15% seed liquid, 1: 1 seed liquid ratio, 5 days fermentation peri- od. Eventually, the protein content of product reached 33.87%, which is 6.85% higher than that of the raw waste.
