So here is the deal, same use different recipies different results to do the same thing. I'll just post some lecture notes and hope that helps:MacConkey's Agar (enterics)Selective for gram negativeCrystal violet and bile salts prevent non-entericsDifferential for lactose fermentationNon-fermenter --> white/clear coloniesFermenter--> red/pink coloniesEosin Methylene Blue (EMB) (Weakly selective for intestinal pathogens)Selective for gram negativeEosin and methylene blue inhibit gram positive growthDifferential for lactose fermentationLactose fermenters produce a green-metallic sheenNon-fermenters do notNOTE: EMB Agar is not in common use anymore
