摘要： An efficient, rapid ex-situ detoxification has been developed to reduce inhibitor concentration and enhance acetone-butanol-ethanol (ABE) production from brewery industry liquid waste (BLW) and brewery spent grain (BSG). About 80±2.0% extraction of furan derivative 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 been obtained. Ex-situ extraction of microbial inhibitors from BLW and BSG hydrolysates using bis-(2-ethylhexyl) sebacate as solvent leads to high production of ABE of 12.67 g/L and 11.23 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 bio-butanol from agro-industrial waste.

摘要： The present document describes a process for production of hydrogen gas (H2) from fermentation of crude glycerol with a hydrogen producing microorganism in a bioreactor. The process comprises the step of introducing a volume of crude glycerol in a fermentation mixture which comprises a fermentation medium comprised of crude glycerol and hydrogen producing microorganisms under a fermentative hydrogen production condition, and then removing a volume of the fermentation mixture equal to the second volume of the crude glycerol, to maintain constant the total volume of the fermentation mixture.
