摘要

丁酸是一种四碳脂肪酸,是一种重要的工业化学品和原料。为了生产这种化学物质,在饲料培养基中加入浓度为 126.5 g.L-1 的葡萄糖进行对照发酵。在这种培养基中,菌株产生 44.8 g.L-1 总酸,生产率为 0.23 g.L-1h-1,产量为 0.41 g.g-1。该菌株(酪酸梭菌 ATCC 25755)还能同时利用葡萄糖和木糖,发酵性能相似。该菌株还被用于利用热水预处理从小麦秸秆水解物(WSH)中生产丁酸。在批处理系统中,该菌株的生产率和产量分别为 0.27 g.L-1h-1 和 0.44 g.g-1,比单独使用葡萄糖或木糖或两者的混合物有所提高。为了提高反应器的生产率,使用了膜细胞循环生物反应器,生产率达到 1.89 g.L-1h-1。这一生产率是葡萄糖或木糖间歇发酵生产率的 822%。此外,还利用 XAD-4 吸附树脂开发了丁酸回收方法。在该系统中,进料中使用了多达 206.1 g.L-1 的丁酸,由于吸附速度快,残余丁酸浓度为 29.5 g.L-1。在该实验中,酸的去除率达到了 1059.4 g.L-1h-1。

Novel Technologies for Butyric Acid Fermentation: Use of Cellulosic Biomass, Rapid Bioreactor, and Efficient Product Recovery
Butyric acid, a four-carbon fatty acid, is an important industrial chemical and feedstock. To produce this chemical, a control fermentation was run with a 126.5 g.L−1 glucose concentration in the feed medium. In this medium, the strain produced 44.8 g.L−1 total acid with a productivity of 0.23 g.L−1h−1 and a yield of 0.41 g.g−1. The strain (Clostridium tyrobutyricum ATCC 25755) was also able to utilize glucose and xylose simultaneously with similar fermentation performance. The culture was also used to produce butyric acid from wheat straw hydrolysate (WSH) employing a hot water pretreatment. In a batch system, the strain resulted in a productivity and yield of 0.27 g.L−1h−1 and 0.44 g.g−1, respectively, which was an improvement over the use of glucose or xylose alone or mixtures of both. To improve reactor productivity, a membrane cell recycle bioreactor was used which resulted in a productivity of 1.89 g.L−1h−1. This productivity was 822% of that achieved in the glucose or xylose batch fermentation. Furthermore, a butyric acid recovery method was developed using XAD-4 adsorbent resin. In this system, up to 206.1 g.L−1 of butyric acid was used in the feed and, as a result of the quick adsorption, the residual butyric acid concentration was 29.5 g.L−1. In this experiment, the rate of acid removal of 1059.4 g.L−1h−1 was achieved.
