| 摘 要： | 以淀粉废水经水解所得的糖液为培养液,利用二代种子酵母的菌种,在一容积为25 L的塔式发酵器内进行了面包酵母的连续培养试验。试验结果为:在冲稀速度D=0.224 h~(-1)下,酵母在发酵液中的浓度C=13.04 g/L(菌体干重),酵母对糖的利用率Y_(X/S)=0.323。这可同目前国内外以糖蜜为原料生产面包酵母的指标相媲美。经本工艺处理的淀粉废水,COD去除率达70％,从而大大减少了废水对环境的污染负荷。

| Abstract: | The experiments of continuous culture of bread yeast havebeen done in a 25 liters of column fermentor. In the experiments the starch-containing waste water was converted into glucose liquid, which was used asculture medium, and the second generation of bread yeast was used as thestrain. The results of experiments are as follows:the concentration of yeast inthe medium C = 13. 04 g/L(DYW)and utilization cofficient of yeast to glu-cose Y_(x/3) = 0. 323 (dilution rate D = 0. 224 h~(-1) ). These results were aboutsame as or over that of culture of bread yeast by using of molasses medium inhome and abroad. Through this process COD in the waste water can be re-moved about 70 percent. So the pollution load of waste water on environmentwas largely reduced. |
