  • This article highlights the work of a team at IIT Roorkee in developing an enzyme to break down DEHP, a common plasticizer

  • The problem: Plasticizers, particularly DEHP, are widely used in various products and are harmful to the environment.   

  • Di-(2-ethylhexyl) phthalate (DEHP) is a chemical that makes plastics more flexible

  • It's a colorless, viscous liquid with little odor that's soluble in oil but not in water

  • DEHP is also known by the names dioctyl phthalate (DOP) and bis(2-ethylhexyl) phthalate (BEHP)

Plasticizers are substances that are added to plastics and other polymers to make them more flexible, easier to shape, and less viscous

  • The solution: Researchers at IIT Roorkee have identified an esterase enzyme produced by Sulfobacillus acidophilus bacteria that can effectively degrade DEHP.   

  • Mechanism of action: The enzyme breaks down DEHP into smaller compounds, which can then be further degraded by other enzymes into harmless substances like water and carbon dioxide.

  • Potential applications: This enzyme has the potential to be used in bioremediation techniques to clean up contaminated environments.

  • Future directions: The researchers are working on integrating multiple enzymes into a single bacterial system to accelerate the degradation process and improve its efficiency.

  • This research has significant implications for environmental remediation and the development of sustainable solutions to plastic pollution. 

  • By utilizing naturally occurring enzymes, scientists can develop eco-friendly and cost-effective methods for breaking down harmful plasticizers and mitigating their environmental impact.
