Making Media

The purpose of culture plates is:

• to isolate colonies

• grow lots of bacteria

• grow mobile bacteria

Liquid cultures are good for

• isolating colonies

• testing for antibiotic resistance

• growing mobile bacteria

• growing lots of bacteria fast

The two main types of media are

• liquid culture

• culture (petri) plates

• aerosolized culture

• sublimative plates

If you want to determine the specific type of strains present in a culture you would use

• general media

• enriched media

• selective media

• differential media

If you want to grow a specific bacteria and inhibit everything else you would use

• general media

• enriched media

• selective media

• differential media

You just want to grow bacteria, nothing fancy. You would use_

• general media

• enriched media

• selective media

• differential media

You've been tasked with growing picky bacteria that require a specialized diet in order to grow.

• general media

• enriched media

• selective media

• differential media

By following aseptic techniques you will reduce contamination of
