摘要: 以木薯液化清液作为发酵底糖,按3∶1的比例添加玉米浆和豆饼粉的混合物作为补充氮源,配制成蛋白质含量为0.6%(m/m)的发酵培养基,在该条件下进行柠檬酸发酵,发酵周期60 h,产酸16.8%(m/v),残总糖0.8%(m/v),转化率98.8%.
Abstract: Cassava liquefied supernatant was used as sugar, and corn syrup and soybean meal were added as nitrogen for citric acid fermentation according to the proportion of 3:1 to prepare the fermentation medium with total protein content of 0.6% (m/m). Under the conditions, the fermentation cycle was 60 h; the ratio of citric acid was 16.8% (m/v); the total sugar residues was 0.8% (m/v); and the ratio of transforming was 98.8%.
