what is a selective medium?
examples of selective medium
Suggestion by K.C.
Certain bacteria can metabolize certain components in the medium. This means that you can “select” for the growth of certain kinds of bacteria based on their nutritional needs.
Also, there are antibiotic-resistant strains that can be “selected” for when you include specific antibiotics in making your medium.

Selective media is used to select for the growth of a particular type of organism. They usually have a specific pH or component that inhibits the growth of certain organisms. MacConkey agar contains bile salts and crystal violet which inhibits the growth of Gram positive organisms. Eosin Methylene Blue agar (EMB) is also selective for Gram negatives. Phenylethlene agar (PEA) is selective for Gram positives and so is Mannitol Salt Agar (MSA). Hope that helps.

All media “brainwashes” the people the tune into it. That’s not evil…it’s just an inherrent trait of the media.
Suggestion by Bronwyn
Absolutely! When all the stations/channels are spouting the same misinformation, and people don’t take the time to do their own research, of course we believe what these people say. 🙁
