Match each type of agar plate to the corresponding general characteristics of each.
Also known as lysogeny broth, it is a multi-purpose media capable of growing a wide variety of microorganisms.
A. LB Agar
B. Mannitol Salt Agar
C. MacConkey Agar
D. Columbia CNA Agar
A. LB Agar
Match each type of agar plate to the corresponding general characteristics of each.
Red in color and is both a selective and differential media. This agar is selective for Gram-positive bacteria and
can differentiate members of the Staphylococci family.

B. Mannitol Salt Agar
Match each type of agar plate to the corresponding general characteristics of each.
Pale red in color and is both selective and differential media. The presence of crystal violet and bile salts in its
formulation restricts Gram- positive bacterial growth. As such, only Gram- negative microbes can be grown.
A. LB Agar
B. Mannitol Salt Agar
C. MacConkey Agar
D. Columbia CNA Agar
C. MacConkey Agar
Match each type of agar plate to the corresponding general characteristics of each.
Red in color and is an enriched, selective, and differential media. It contains the antimicrobial agents colistin and
Nalidixic acid, it suppresses the growth of Gram-negative bacteria and is, therefore, used for isolation of Gram-
positive microbes.
