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:
A method for characterizing terahertz radiation using spectral domain interferometry, comprising overlapping a pump beam and a terahertz beam in a detecting crystal; obtaining two probe pulses by propagating the probe beam into a polarization maintaining single-mode optical fiber after the detecting crystal; and measuring a change in the optical path difference between the two probe pulses. The system comprises a detection crystal, where a terahertz pulse and a probe beam are made to overlap; a polarization-maintaining optical fiber propagating the probe beam after the detection crystal and outputting two probe pulses; and a spectrometer where the two probe pulses interfere.
