Enhanced volatile fatty acid production via the batch electrodialysis of a dark fermentation fermenter continually fed with sucrose

摘要：

　　Volatile fatty acids (VFAs) are important chemicals in terms of their energy content and their economic value.VFAs have also been considered as byproducts of mixed acid fermentation,a process designed to produce sustainable hydrogen to combat the well-known and growing issues surrounding fossil fuels.The accumulation of VFAs during mixed acid fermentations inhibits both the production of hydrogen and VFAs.Electrodialysis (ED) was used successfully to remove VFAs from a continually fed sucrose fermenter and in doing so increased VFA production by up to 53% and hydrogen production by 375% compared to controls.Further work using more intensive ED could lead to greater substrate utilisation and higher yields of VFAs and hydrogen.
