Liquid Culture Media

These media do not contain any traces of solidifying agents, such as agar or gelatin, and large growth of bacterial colonies can be observed in the media. Liquid media are also called broths, they allow for uniform and turbid growth of bacterial strains when incubated at 37ºC for 24hrs. The media is used for the profuse growth of microorganisms and fermentation studies. Examples include Tryptic soy broth, phenol red carbohydrate broth, MR-VP broth, and nutrient broth.
