Pfizer selective enterococcus agar overlay method for the enumeration of faecal streptococci by membrane filtration. This page was last edited on 26 Februaryat Compendium of methods for the microbiological examination of foods. Statistical validation criteria for drinking-water microbiological methods. Evaluation of media for the enumeration of faecal streptococci from natural water samples. Among them are enterococci, which are considered to be good indicators, since they survive for a longer time in adverse natural conditions.

Enterococcus hydrolyze esculin to products that react with ferric citrate in the medium to produce insoluble iron salts, resulting in the blackening of the medium. Characterization and validation of a chemiluminescent assay based on a 1,2-dioetane for rapid detection of enterococci in contaminated water and comparison with standard methods and qPCR. The first three parameters were esculin for both methods before and after confirmation by biochemical testing. A rapid, specific membrane filtration procedure for enumeration of enterococci in recreational waters.
Bile Esculin Agar BEA is a selective differential agar used to isolate and identify members of the genus Enterococcus formerly part of the “group D streptococci” enterococci were reclassified in their own genus in J Appl Sci Res.
