| Abstract: | The fermetation liqor concentration of the burdening materital somewhat increased that original fermentation liquor increased suger reserve <2%. In this essential fermentation theglucoamylas activity to average about 16860.8unit/ml and the highest activity was about17925unit/ml. the fermentation period was average about 107.2 hours and enzyme activityabout 157unit/ml per hour was produced. |
