Enriched media and enrichment media are both types of culture media used to cultivate and grow microorganisms in a laboratory setting. The key difference between the two is that enriched media contains added nutrients that support the growth of a wide variety of microorganisms, while enrichment media contains specific nutrients that promote the growth of a particular type of microorganism.

Here is a table summarizing the differences between enriched and enrichment media:

Criteria Enriched Media Enrichment Media
Definition Media that contain additional nutrients Media that contain specific nutrients
Purpose Supports the growth of a wide variety of microorganisms Promotes the growth of specific microorganisms
Composition Rich in nutrients like blood, serum, or yeast extract Contains specific nutrients like antibiotics or growth factors
Examples Blood agar, Chocolate agar, Nutrient agar MacConkey agar, Sabouraud dextrose agar, Thayer-Martin agar
Selectivity Non-selective Selective
Targeted microbe type Non-specific Specific
Used for Routine culture Identification of specific microorganisms
