M-EI Chromogenic Agar Base 500g Condalab 1412
m-EI Chromogenic Agar Base is for the detection and enumeration of enterococci in water by the membrane filter technique. The medium was developed for single-sterp procedures that does not require the transfer of the membrane filter to another substrate. The presence of enterococci is confirmed by blue coloured colonies. A wide range of sample volumes or dilutions are tested by the single-step membrane filtration procedure for the detection and enumeration of enterococci in potable, fresh, estuarine, marine, and shellfish-growing waters.
The peptone in the medium provides nitrogen, vitamins, minerals, and amino acids that are essential for growth and the yeast extract gives trace elements, vitamins, and amino acids. Esculin is hydrolyzed by enterococci to form esculetin and dextrose. The cycloheximide inhibits most fungi, and sodium azide inhibits gram-negative bacteria. X-Glucoside is the substrate of the glucosidase-positive enterococci and the agar is added into the medium as a solidifying agent.
