【摘要】 以马铃薯淀粉生产的废水及废渣为原料,采用微生物发酵的方法,制备高附加值的蛋白饲料,同时降低废水的COD值,达到综合利用的目的。经试验筛选得到1株酵母,并确定了蛋白饲料的制备条件:废水中薯渣添加量20%、pH自然、温度28℃、接种量10%、发酵时间72 h。在适宜条件下,制备的蛋白饲料蛋白含量达37.40%,废水COD降低72.29%。更多还原

【Abstract】 Microorganism fermentation method was used to produce high value-added protein feed from waste-water and wastes of potato starch production.This can lower COD content in waste-water and comprehensive utilized the potato starch processing wastes.A yeast strain was screened in our laboratory,and the optimum preparation conditions of protein feed was determined as: 20% wastes in waste-water(W/V),natural pH,28℃,inoculation amount 10%,cultivation time 72 h.In the optimum condition,protein content of the protein feed production was 37.40% and waste-water COD decreased 72.29%.更多还原
