Bioremediation

18.1K
Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

Area of Science:

  • Biorefining and Sustainable Chemistry
  • Agricultural Waste Valorization
  • Industrial Biotechnology

Background:

  • The wine industry generates substantial lignocellulosic by-products, such as grape stems.
  • These by-products are often disposed of at a cost, presenting an opportunity for biorefinery feedstock.
  • Valorization of these waste streams aligns with circular economy principles and sustainable resource management.

Purpose of the Study:

  • To develop and demonstrate a sequential biorefining protocol for grape stalk valorization.
  • To obtain valuable by-products, including polyphenols and biopolymers, from grape waste.
  • To produce lactic acid and evaluate the efficacy of polyphenols against wine spoilage microorganisms.

Main Methods:

  • Sequential fractionation of grape stalks using subcritical water and enabling technologies.
  • Physical/chemical and biological treatments for biomass valorization.
  • Membrane treatment for material recycling within the process.
  • Fermentation of cellulose-rich residue using engineered Clostridium thermocellum strains.
  • Antimicrobial activity testing of the polyphenolic fraction.

Main Results:

  • Successful fractionation yielded streams rich in polyphenols, hemicellulose, pectin (13.15% cumulative yield), lignin, and cellulose.
  • Production of up to 5.8 g/L lactic acid from the cellulose-rich residue via fermentation.
  • Polyphenolic fraction demonstrated inhibitory effects against Brettanomyces bruxellensis and Acetobacter pasteurianus.
  • Demonstrated a closed-loop system with membrane-based material recycling.

Conclusions:

  • The study presents a proof-of-concept for a second-generation biorefining process utilizing waste grape biomass.
  • This multidisciplinary approach effectively valorizes lignocellulosic materials into high-value products.
  • The developed process offers a sustainable solution for managing wine industry by-products and generating bio-based chemicals.
