selective media

Selective media are specialized nutrients used in laboratories to grow specific types of microorganisms while inhibiting others. This method helps scientists isolate and study particular organisms from complex mixtures, like soil or water samples. For example, if researchers want to cultivate only bacteria that can break down certain pollutants, they use selective media designed to support those bacteria's growth while preventing others from thriving. This approach is essential in fields like microbiology and healthcare, as it aids in identifying pathogens or beneficial microbes efficiently.
