There's two essential sorts of media readily available for conventional microbiological Investigation: “large nutrient” and “small nutrient”. Large-nutrient media such as plate depend agar (TGYA) and m-HPC agar (formerly m-SPC agar), are meant as normal media for that isolation and enumeration of heterotrophic or “copiotrophic” bacteria. Minimal-nutrient media for example R2A agar and NWRI agar (HPCA), can be beneficial for isolating gradual growing “oligotrophic” bacteria and microorganisms that call for lower amounts of nutrients to increase optimally. Often some facultative oligotrophic microorganisms will be able to mature on high nutrient media and several facultative copiotrophic micro organism have the ability to increase on small-nutrient media, but this overlap isn't comprehensive.
