Enrichment cultures and selective cultures are both techniques used in microbiology to isolate specific microorganisms, but they serve different purposes. An enrichment culture is designed to enhance the growth of a particular organism by providing favorable conditions and nutrients, often allowing rare organisms to proliferate in a mixed community. In contrast, a selective culture uses specific agents (like antibiotics or pH) to inhibit the growth of unwanted organisms, favoring the growth of the target organism. Consequently, while enrichment cultures promote growth, selective cultures control growth.
What are the major differences between an enrichment culture and a selective culture?
