Glucose Salts Agar (GSA) is a selective agar that selects for gram-negative bacteria only. This means that no gram-positive bacteria will be able to grow on it.
Peptone glucose agar (PGA) medium
Minimal salts agar is selective and differential. It grows gram positive bacteria and turns different color depending on what the specimen is.
Escherichia coli or E. coli is capable of fermenting glucose. It is a facultative anaerobe that can metabolize glucose in an anaerobic environment.

Modified nutrient glucose agar is composed of agar, water, glucose, extracts, peptone and sodium chloride. Modified nutrient glucose agar allows organisms to grow.

Potassium tellurite agar is selective for the growth of Staphylococci and is somewhat selective for the growth of Corynebacteria. Staphylococci and Corynebacteria reduce the potassium tellurite in the agar, which makes the colonies grow black.
Salmonella-Shigella (SS) agar. XLD agar. Hekton enteric agar.
Because 7.5% NaCl agar inhibits gram negative organisms from growing, and is "selective" in that only gram positive organisms can grow in this type of agar.
