Abstract

Key findings

  • The MEC system was able to treat 90% of the spent wash effluents within 24 hours.
  • The system produced a maximum biohydrogen yield of 1.2 mol H2/mol glucose.
  • The electro-fermentation process showed a 25% increase in biohydrogen production compared to traditional fermentation methods.
