Document Summary
Lecture 3 microbial nutrition: describe examples of specialised media. Different culture media will be selected for depending on the purpose. Can use agar purified from red algae as a solidifying agent. Defined all the quantities are known and exact. This is the opposite for complex culture media. Peptones are proteins that are hydrolysed by enzyme or acids. Judith bateman: describe examples of specialised media. Specialised media different environments in the media are created depending on what it"s being used for. Use this to transport samples from patients (temporary storage). Allows organisms to survive, but does not allow division. Use this when you want to grow a wide variety or organisms. i. e. grow as many different types as possible. Use this when you want to grow a particular organism. Will allow the target organism to become dominant in the culture media so that it can be detected. Important feature: will keep normal microflora (very high numbers) static in the lag phase.
