Related to chocolate agar: MacConkey agar

choc·o·late a·gar

blood agar heated until the blood turns brownish, used especially to isolate Haemophilus, Neisseria, and other species for which unheated blood is inhibitory.

Blood agar that has been heated to open the pyrrole ring, forming hemin, a required growth factor for bacteria lacking hemolysins. Chocolate agars are usually incubated in a microaerophilic—3–10% CO2—environment, providing ideal growth conditions for H influenzae, Neisseria spp, and fastidious anaerobes
