Mechanistic insights into extracellular reductive dechlorination of hexachloroethane by common non-electroactive bacteria Bacillus subtilis and Escherichia coli

Key Points

• The research aims to explore how Bacillus subtilis and Escherichia coli dechlorinate hexachloroethane in their extracellular environment.
• Examined the ability of Bacillus subtilis and Escherichia coli to dechlorinate hexachloroethane.
• Analyzed the reduction products, pentachloroethane and tetrachloroethylene.
• Conducted experiments in extracellular matrices.
• Both bacteria effectively dechlorinated hexachloroethane to pentachloroethane.
• Tetrachloroethylene was also identified as a product of this process.
