M-Endo broth is used for the estimation of coliform bacteria in water samples using the membrane filtration technique. It is possible to remove bacteria from fluids by passing them through filters with such small pore size that bacteria are arrested. This filtration technique enables fairly large volumes of water to pass rapidly under pressure, but prevents the passage of any bacteria present. These nutrients are retained on the surface of the membrane which is then brought into contact with suitable liquid nutrients. These diffuse upwards through the pores thereby inducing the organisms to grow as surface colonies which can be counted.

Selective medium for the detection of Enterobacter sakazakii in milk powder and powdered infant formula. The base in Chromocult ® Enterobacter sakazakii agar allows good growth and strong colour formation of E. sakazakii colonies. The addition of inhibitors and the incubation temperature of 44 °C largely reduce the growth of the majority of gram-positive and gram-negative accompanying flora. E. sakazakii  is ß-D-glucosidase positive and grows as blue-green colonies on this medium. Incubation: 24 ±2 hours at 44 ±1 °C. Incubation temperature has a strong influence on sensitivity and selectivity of this method. Temperatures higher than 45 °C will inhibit the growth of E.sakazakii. Temperatures below 43 °C will reduce inhibition of accompanying bacteria.
