Paan stain eraser wins students a US award

A team of eight girls from Ramnarain Ruia College, Matunga, Maharashtra, discovered microbes and enzymes that turn the red paan colour into “a harmless colourless product." Railways in Mumbai alone spends crores on scrubbing off paan stains manually. The team got a grant of Rs 10 lakh and a gold medal from the Genetically Engineered Machines (iGEM) 2018 held in Boston, US.
