SULPHITE AGAR

Oxidation of sulphur or sulphides for energy production is restricted to the bacterial genus Thiobacillus, Thiomicrospira, and Sulfolobus. These bacteria all produce sulphuric acid as a metabolic product. The direct reduction of sulphate ions to hydrogen sulphide is effected in nature by specialized, strictly anaerobic bacteria of the genera Desulfovibrio and Desulfotomaculus. These sulphate-reducing bacteria are heterotrophic organisms that utilize sulphate, thiosulphate, S2O3–, sulphite, SO3–, or other reducible sulphur-containing ions as terminal electron acceptors in their respiratory metabolism. In the process these sulphur-containing ions are reduced to hydrogen sulphide. Sulphite Agar is prepared according to the formula described by Clark and Tanner and is recommended by APHA for detecting the thermophilic hydrogen sulphide producing anaerobic microorganisms.
