Microbial Media

This type of media is composed of precise amounts of pure chemicals. It is essential when studying nutritional requirements of bacteria.

• selective media

• differential media

• chemically defined media

• enrichment culture media

This type of media inhibits the growth of organisms other than the one being grown. Can be complex or chemically defined media.

• selective media

• diferential media

• chemically defined media

• enrichment culture media

This type of media contains specific ingredients that help us to visually distinguish which species do or do not carry out a specific biochemical process.

• selective media

• differential media

• chemically defined media

• enrichment culture media

T/F: media can be both selective and differential.

• True

• False

This media selects for gram-negative organisms and isolates lactose fermenters (pink) and non-lactose fermenters (clear).

• choclate agar

• Mannitol salt agar

• Eosin-methylene blue (EMB) agar

• MacConkey agar

This is a general purpose medium that supports the growth of a wide variety of bacteria.

• blood agar

• nutrient agar

• chocolate agar

• MacConkey agar
