摘  要:
以菠萝皮渣为发酵原料,通过绿色木霉和啤酒酵母混菌发酵,生产高蛋白质生物饲料,并对其发酵条件进行优化。正交试验结果表明,发酵产物粗蛋白质含量最高的培养条件为:硫酸铵添加量3%、料水比1∶0.3、酵母接种量15%,发酵温度33℃、发酵时间108 h,在优化的培养条件下,发酵产物的粗蛋白质含量可达26.98%,可作为优质的蛋白质饲料。

摘  要:
The mixed fermentation that included Trichoderma viride and Saccharomyces cerevisiae was studied for the production of high protein bio-feed from pineapple pericarp by orthogonal design experiments.The optimal fermentation condition showed as follows:ammonium sulfate 3%,the ratio of material and water was 1∶0.3,the inoculation amount of yeast was 15%,then 33 ℃ ferment 108 h,the protein of feed could reach 26.98%,which could be used as quality protein feed.
