Notes:
IIT Roorkee researchers developed a method to degrade plasticizers like diethyl hexyl phthalate (DEHP) using bacterial enzymes. DEHP is found in plastics and personal care products, posing health risks. Esterase enzyme from Sulfobacillus acidophilus breaks DEHP into mono-(2-ethylhexyl) phthalate (MEHP) and 2-ethyl hexanol. The enzyme was structurally studied using X-ray crystallography and remains active for about a month. Researchers used four additional enzymes from Comamonas testosteroni to complete the degradation process. Integrating enzymes into bacteria ensures prolonged activity and continuous degradation without needing fresh batches. Plasticizers enhance flexibility and shine in products but can be absorbed through the skin, posing health dangers.
