La présente partie de l'ISO 9308 spécifie une méthode miniaturisée pour la recherche et le dénombrement d'Escherichia coli (E. coli) dans les eaux de surface et résiduaires par ensemencement en milieu liquide. La présente méthode est applicable à tous les types d'eaux de surface et résiduaires, plus particulièrement celles riches en matières en suspension. La présente méthode n'est pas applicable à l'eau potable ou tout autre type d'eau dont la valeur guide est inférieure à 15 pour 100 ml. La présente méthode ne convient pas à la recherche et au dénombrement de bactéries coliformes autres que les E. coli.
Abstract
Overview
ISO 9308-3:1998 specifies a miniaturized Most Probable Number (MPN) method for the detection and enumeration of Escherichia coli (E. coli) in surface water and waste water. The method uses inoculation of serial dilutions into dehydrated liquid culture medium in 96‑well microtitre plates and detects β‑D‑glucuronidase activity using the fluorogenic substrate MUG. Results are reported as an MPN per 100 ml with 95% confidence intervals. The method is not intended for drinking water (or other waters with guideline
