Researchers turn yoghurt waste into biofuel ingredient
Germany and US-based researchers have discovered a way to use microbes for turning Greek yogurt waste into molecules for biofuel production. Waste whey from yogurt production is made up of milk sugar lactose, fruit sugar fructose, and lactic acid. The team used bacteria to turn this mixture into small "green antimicrobials" which could be stitched to make biofuel carbon chains.
