_____ Medium Contains All of the Substances Required by Bacteria

Question

_____ medium contains all of the substances required by bacteria for growth and reproduction.
A)Minimal
B)Complete
C)Auxotrophic
D)Selective
E)Liquid

Accepted Answer

A complete medium contains all of the necessary nutrients, such as sugars, amino acids, vitamins, and minerals, for bacterial growth and reproduction. Minimal medium contains only the bare minimum nutrients required for growth, while auxotrophic medium lacks one or more essential nutrients that the bacteria cannot synthesize themselves. Selective medium contains specific chemicals or nutrients that favor the growth of certain types of bacteria, and liquid medium simply refers to the physical state of the medium (as opposed to solid medium).
