Economic optimization of in situ extraction of inhibitors in acetone-ethanol-butanol (ABE) fermentation from lignocellulose
VHG Díaz, GO Tost - Process biochemistry, 2018 - Elsevier
The inhibitors produced in the pretreatment (phenolics, furans, and organic acids) as well as
in the fermentation (butanol and organic acids) limit acetone, butanol, and ethanol (ABE)
production from lignocellulose. To reduce their negative impact on the fermentation, a
process involving simultaneous saccharification, ABE fermentation, and detoxification by
liquid–liquid extraction was proposed and economically optimized. Although several
extractants may be used to reduce butanol toxicity increasing the reactor performance …
