Enrichment

Definition

continues to cultivate under conditions suitable for target microorganisms without suitable for other microbial growth, the target microorganism will become a dominant species to obtain pure culture. This approach was created by Vinagladski and Beyelink in the 1990s, and they have been successfully separated from nitrated bacteria and sulfate reduction bacteria.

principle

Enrichment Culture: A type of culture method that causes a particular microbial proportion in mixed microorganisms. It can be used to promote selective medium or culture conditions that promote a particular microbial growth reproduction, which can be used to inhibit selective medium or culture conditions of other microorganism growth reproduction. AsHby medium, a Martin medium such as a nitrogen-free medium used in proliferating aerobic nitrogen, proliferating soil fungi, and the like. The three can be used continuous culture method, and a cells having a small rate than the growth rate of the growth rate are left in the culture in the culture.

It is to make specific environmental conditions for different microbial life activities, making it only for microorganisms that apply only to this condition.
