Question

Quizplus · Accepted Answer

Selective media are designed to support the growth of one type or group of microbes, while inhibiting the growth of others. This is typically achieved through the addition of specific nutrients, growth inhibitors, or chemicals that are toxic to certain groups of microbes. Selective media can be used to identify specific pathogens or to isolate particular groups of bacteria from complex samples.
