identification of enteric organisms and is also used in the isolation of pathogens from foods and coliforms in water samples. Like HE agar, MAC incorporates bile salts, in addition to sodium chloride, which inhibits the growth of most Gram-positive bacteria. Differentiation of enteric microorganisms is achieved by the fermentation of lactose

SULFIDE-INDOLE-MOTILITY (SIM) TEST
crcooper01.people.ysu.eduFinally, indole production is detected in SIM medium due to the presence of casein peptone, an ingredient rich in tryptophan. Organisms that possess the enzyme tryptophanase degrade tryptophan to generate indole, pyruvic acid, and ammonia. The latter two are used for a cell’s nutritional needs, whereas indole is not and accumulates in the medium.
