Overheating can cause darkening of the m edium according to ISO PresentationPrepared Plates Packaging Details Shelf life Storagemm with±mlbox withpacks ofplates/pack. In our study, it was observed that membranes having more than presumptive colonies had a false negative rate as high as % Mix well and dissolve by heating with frequent agitation. Specification. This part of ISO is especially intended Bile Esculin Azide Agar ISO Selective medium for the isolation and presumptive identification of intestinal enterococci by Membrane filtration method ISO Water quality Detection and enumeration of E. coli and coliforms. Single cellophanemonths ºC Description and Technique Description Bile Esculin Azide Medium is a modification of the classical Bile Esculin proposed by Isenberg, Goldberg and In the ISO –2 method, membrane filters (usuallymm in diameter) with the presumptive enterococci colonies are transferred from the Slanetz and Bartley medium to the pre-heated BEA medium for confirmation. Solid medium for the confirmation and enumeration of enterococci in water by the membrane filtration The categorical performance characteristics of the ISO –2 method are presented in TableOverall, the results indicate that the method is sufficiently sensitive, specific, ISO A standard is reviewed everyyears. information oductionIn this part of ISO a method is This part of ISO specifies a method for the detection and enumeration of intestinal enterococci in water by membrane filtration.
