Spirit-based distillers' grain (SDG) is the main by-product of the Chinese liquor industry, with an annual output of approx. 100 million tons. The economical potential of fermentative production of succinic acid from SDG was investigated using Actinobacillus succinogens. Use of pretreated SDG (PSDG) as the sole source of C and N yielded succinic acid at 35.5 g l(-1) with a yield of 19.7 % (g per 100 g PSDG) after 48 h in a 3 l stirred bioreactor. SDG is thus a promising feedstock for the economical production of succinic acid.
基于精神的蒸馏器谷物（SDG）是中国白酒行业的主要副产品，年产量约为 1 亿吨。使用 Actinobacillus succinogens 从 SDG 发酵生产琥珀酸的经济潜力进行了研究。使用预处理的 SDG（PSDG）作为唯一的 C 和 N 源，在 3 L 搅拌生物反应器中 48 小时后，琥珀酸的产量为 35.5 g/L，产率为 19.7%（每 100 g PSDG）。因此，SDG 是经济生产琥珀酸的有前途的原料。
