There are 2 standard types of media obtainable for traditional microbiological Investigation: “higher nutrient” and “minimal nutrient”. Superior-nutrient media for example plate count agar (TGYA) and m-HPC agar (formerly m-copyright agar), are meant as basic media for the isolation and enumeration of heterotrophic or “copiotrophic” bacteria. Very low-nutrient media like R2A agar and NWRI agar (HPCA), could possibly be helpful for isolating gradual growing “oligotrophic” germs and bacteria that require reduce levels of nutrients to expand optimally. Frequently some facultative oligotrophic microorganisms are able to increase on substantial nutrient media and some facultative copiotrophic microorganisms are able to increase on small-nutrient media, but this overlap will not be total.
