What are chemoheterotrophs?

Back

Organisms that obtain both carbon and energy from organic compounds.

Front

What is the role of differential media?

Back

Media that allows for the differentiation of closely related organisms based on their biological characteristics.

Front

Define mixotrophs.

Back

Organisms that can use both autotrophic and heterotrophic modes of nutrition.
