Effect of wine pomace extract on dechlorination of chloroethenes in soil suspension

Abstract Chloroethenes are widely used as solvent in the metal industry and dry cleaning industry, but their spillage into soil groundwater due to improper handling has negatively impacted human health. Bioremediation using microorganisms is one of technologies clean up contaminated with chloroethenes. In this study, we examined bioremediation chloroethene-contaminated wine pomace extract (WPE). WPE a liquid containing seven major carboxylic acids other substances extracted from grape produced winemaking. clearly promoted anaerobic tetrachloroethene (PCE) degradation test that fractions derived WPE, water-eluted fraction l -lactic acid, -tartaric others dechlorination PCE, whereas methanol-eluted mainly syringic acid did not. another PCE solutions, enhanced The results suggest function hydrogen donors microbial chloroethene. This technology realizes environmental remediation through effective use food by-products. Graphical
