WLN-BM.W.08.2Determination of the amount of enterococcus by means of membrane filtration.in accordance with NEN-EN-ISO 7899-2
Principle:The sample is filtered through a suitable membrane filter. Next the filter is incubated at 37 °C on a solid, azide-containing culturemedium with such selective characteristics that enterococcus will form characteristic colonies. Confirmation of this characteristic colonies is executed by MALDI-TOF.
Determination:Enterococcus
