Abstract

As butyric acid is an important chemical raw material,using cheap non-grain biomass and FBB(fibrous-bed bioreactor)immobilized fermentation to produce butyric acid has important significance.The investigation showed that the four-column parallel immobilized fermentation technology can greatly improve the production efficiency due to the decrease of fermentation recycle to half.In the fermentation with cassava dregs hydrolysate as substrate,25.2 g/L butyric acid was obtained and the yield was 0.46g/g.At last,the production of butyric acid was increased to 61.4g/L through fed-batch fermentation.

Key words： brous-bed bioreactor; cassava dregs hydrolysate; butyric acid; fed-batch
