M-ENDO BROTH

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.
M-Endo Broth is used for milk lines of milk handling equipment and for examination of swimming pool waters which use membrane filter technique. Higher counts are given in this medium and is most satisfactory of the many media used, since coliform colonies develop rapidly it doesn?t require the preliminary enrichment and saturated relative humidity and results of Standard Methods MPN Test are in good agreement.
