Abstract / scope

Describes a combined method for the enumeration of presumptive Escherichia coli and of presumptive coliforms by means of a culture technique involving a liquid medium with 4-methylumbelliferyl-ß-D-glucuronide (MUG), calculation of the number of Escherichia coli per gram or per millilitre by the most probable number (MPN) technique after incubation at 30 °C.
