Study Notes

Media Types for Microorganism Cultivation

Minimal media: Contains the bare minimum nutrients for microbial growth, often lacking amino acids.
Selective media: Supports the growth of specific microorganisms while inhibiting the growth of others.
Differential media (Indicator media): Distinguishes between different microorganisms based on their biochemical properties, even if they are grown together.
Transport media: Preserves and temporarily stores specimens during transport to the lab for analysis, consisting primarily of buffers and salts.
Enriched media: Contain added nutrients to support diverse microbial growth, especially those demanding particular nutrients.
