Compact Dry is a simple and safe procedure for determining and quantifying microorganisms in food, cosmetics and other raw materials, including pharmaceuticals. The ready-to-use Compact Dry chromogenic plates are suitable for both in-process and final product controls.

Coliforms are characterized by being gram-negative bacilli that do not form spores, defined by their ability to ferment lactose. spore-forming, defined by their ability to ferment lactose, to produce acid and/or carbon dioxide gas. The enzyme in charge of degrading lactose is the β-galactosidasa and all bacteria of the coliform group possess it. On the other hand Escherichia coli has an extra enzyme called β-glucoronidasa. Compact Dry EC is capable of detecting the enzyme β-galactosidasa of the coliforms and the enzyme β-glucoronidasa de E. coli of the coliforms and the enzyme
