The enrichment culture
is a primary isolation technique designed to make conditions of growth
very favorable for an organism of interest while having an unfavorable
environment for any competing organisms. Enriched media is
the specific medium designed so that fastidious organisms (those with unusual
requirements for growth) will be supported. For example, using the
enrichment culture technique: when trying to isolate a halophile, streak
plates of varying high salt concentrations (an enriched medium).
The halophile will thrive on the salty media, while other organisms will
not be able to tolerate it and will die out.
