Faecal streptococci often tend to linger much longer in the atmosphere than thermotolerant or overall coliforms and are extremely resistant to drying. It is, for that reason, possible to isolate faecal streptococci from water which contains couple of or no thermotolerant coliforms as, as an example, when the source of contamination is distant in either time or space from the tasting point.

The filter is then moved aseptically to the surface of an agar plate, or an absorbing pad saturated with an appropriate careful medium and nurtured.

MF techniques fast and very easy to do, require little incubator room, and can manage big volumes of water if required.

There are a number of official released techniques based on MF, notably a collection of ISO techniques, such as ISO 9308-1 for coliforms and E. coli and ISO 7899-2 for enterococci. Much selective media have actually been established for the detection of indicator microorganisms in water by MF approaches. Suggested media for coliforms and E.in cooling towers should be performed regularly and must be part of a plant's program of testing.
