Scientists have developed a special enzyme from heat-loving bacteria that can break down tetracycline antibiotics in wastewater. Using this enzyme called FNTL along with a natural chemical helper called acetosyringone, they were able to eliminate over 90% of tetracycline in laboratory tests. This breakthrough offers a promising new way to clean up pharmaceutical pollution in water, which is important because antibiotics in the environment can contribute to the development of antibiotic-resistant bacteria.
