Within the carboxylate platform, carboxylic acids are seen as important building-blocks for the chemical industry, but their recovery is challenging. Membrane based reactive extraction (MBRE) was evaluated for the recovery of these acids from a fermentor in which a mixed culture is converting biorefinery wastewater to carboxylates. Both off-line and in-line experiments were performed. The off-line experiments were promising and extraction efficiencies of 15 (acetic acid) to almost 100% (caproic acid) were reached. The in-line experiments confirmed the selective and near complete extraction of carboxylates with longer chain length. However the overall extraction rates were lower than in off-line tests and the total carboxylate production rate was also decreasing. This was probably caused by limited but repeating contact between organic phase and fermentation broth via the membrane interface.

在羧酸盐平台内，羧酸被视为化学工业的重要组成部分，但其回收具有挑战性。评估了基于膜的反应萃取（MBRE）从发酵罐中回收这些酸的情况，在发酵罐中，混合培养将生物精炼废水转化为羧酸盐。进行了离线和在线实验。离线实验很有希望，提取效率达到15（乙酸）至几乎100％（己酸）。在线实验证实了具有较长链长的羧酸盐的选择性和近乎完全的提取。但是，总提取率低于离线测试，总羧酸盐生成率也在下降。
