With addition of supplements and hemoglobin an enriched medium for growth of fastidious bacteria.

Various workers led to the development of an agar medium for the cultivation of Neisseria sp. Carpenter et al. increased the recovery time of Neisseria sp. by reducing the agar content. The enrichment of the medium with hemoglobin and yeast concentrate also greatly improved the growth of Neisseria sp. Heated hemoglobin releases hemin which is a growth factor for fastidious microorganisms such as Haemophilus sp. Cofactors, vitamins and nicotinamide adenine dinucleotide (required by Haemophilus sp.) are present in the chemical enrichment. Chocolate Agar is composed of GC Agar Base, hemoglobin and enrichment. Thayer-Martin Agar is Chocolate Agar with the addition of vancomycin to suppress Gram positive microorganisms, colistin to suppress Gram negative microorganisms and nystatin to inhibit yeast. Anisomycin is substituted for nystatin in Martin-Lewis agar.
