Butanol extraction
WebA novel acetone–butanol production process was developed which integrates a repeated fed-batch fermentation with continuous product removal and cell recycle. The inhibitory product concentrations of the fermentation by Clostridium acetobutylicum were reduced by the simultaneous extraction process using polyvinylpyridine (PVP) as an adsorbent. WebFeb 26, 2024 · Extraction efficiency of butanol was reduced in studies with hexane-based Winsor III microemulsions using a two-step approach (coacervation followed by back-extraction). However, when compared to the two-stage method, the single-step method with hexane reduced a step and resulted in four times more butanol extraction (Gedam …
