Enrichment culture

Enrichment culture

An enrichment culture is a medium with specific and known qualities that favors the growth of a particular microorganism. The enrichment culture's environment will support the growth of a selected microorganism, while inhibiting the growth of others. Lourens Bass-Becking succinctly summarized enrichment cultures' abilities when he said "everything is everywhere; the environment selects."

Van Stockum & Zoon |title=Geobiologie of inleiding tot de milieukunde |volume= |issue= |pages=]

The botanist Martinus Beijerinck is credited with developing the first enrichment cultures.

Bakteriologie, II |volume=7 |issue= |pages=33-61] Sergei Winogradsky also experimented on bacteria using different cultures. [cite journal| last=Winogradsky |first=Sergei | year=1890 |title=Sur les organismes de la nitrification |journal=Comptes rendus de l'Académie des Sciences |volume=110 |issue= |pages=1013-1016]
