Abstract
An efficient, rapid, ex-situ two phase partitioning detoxification has been developed to reduce inhibitor concentration in biomass hydrolysate and enhance biobutanol production from brewery liquid waste (BLW) and brewery spent grain (BSG). About 80 ± 2.0% extraction of furan derivatives and more than 95 ± 2.0% extraction of phenolic compounds and almost no extraction of reducing sugar from simulated synthetic media as well as real waste hydrolysate have made this method more interesting. Detoxification of brewery liquid waste and brewery spent grain hydrolysate by over liming and charcoal gave biobutanol production of 4.3 g/L, 6.3 g/L and 4.6 g/L, 5.8 g/L respectively. Ex-situ extraction of microbial inhibitors from brewery liquid waste and brewery spent grain hydrolysates using bis (2-ethylhexyl sebacate) as extractant gave biobutanol production of 8.0 g/L and 7.2 g/L respectively. Lower power consumption (0.081 W/L) and reuse of the extracting solvent made this detoxification technique extremely useful for improving production of biobutanol from agro-industrial waste.
