Minimal medium typically contains: This supplementation allows for the culturing of specific lines of auxotrophic recombinants. Selective media[ edit ] Blood-free, charcoal-based selective medium agar CSM for isolation of Campylobacter Blood agar plates are often used to diagnose infection.

On the right is a positive Streptococcus culture; on the left is a positive Staphylococcus culture.

The selective and differential culture media are opposites to each other in a way that one inhibits the growth of other organisms while allowing the growth of some while the other does not kill the others but only highlights one type.

Blood agar is a common differential culture medium used to identify types of media in microbiology that causes haemolysis in blood.

Resuscitation Culture Media This is a special type of media which is used for growing microorganisms that are damaged and have lost the ability to produce due to certain harmful environmental factors.

This culture allows the organisms to regain their metabolism by providing the nutrients that the organisms had been deprived of. For example, a type of bacteria that requires histamine for its growth is subjected to a medium lacking this essential component its types of media in microbiology will be inhibited.

If the same bacteria is then placed in a medium consisting of histamine it will start to grow again.

Laboratory Media

In this case the media containing histamine will act as resuscitation media. MacConkey agar, Lowenstein-Jensen media, tellurite media Tellurite inhibits the growth of most of the throat organisms except diphtheria bacilli.

Antibiotic may be added to a medium for inhibition. An indicator is included in the medium.

A particular organism causes change in the indicator, e. Examples include Triple Sugar Iron agar, Simmon's citrate agar, urea agar, carbohydrate broth tubes, amino acid decarboxylase or dihydrolase tubes, MIO medium for motility, indole, and ornithine decarboxylaseand MacConkey agar.

Some media can be both selective and differential. In the broadest sense, all media are selective, in that there is no universal medium on which all species of bacteria can grow.
