EMB (eosin-methylene blue) agar is used as a selective and differential medium to isolate and identify gram-negative bacteria, particularly coliforms like E. coli, in food, water, and pharmaceutical products. It differentiates bacteria based on their ability to ferment lactose, with lactose-fermenting bacteria producing dark colonies that may have a metallic green sheen, while non-fermenters remain colorless or pink.
