Quality Control Specifications
Homogeneous powder, free-flowing and light beige. Visually the prepared medium is clear to slightly hazy and light to medium pinkish-beige. Expected cultural response after 18-48 hours at 35ºC.
m-Enterococcus Agar is an improved agar which was found to be superior in the isolation, selectivity and enumeration of enterococci found in heavily polluted waters. Using m-Enterococcus Agar, higher counts for enterococci were obtained when compared to the standard MPN procedures. The addition of 0.2% sodium carbonate and 0.05% Tween 80 to this medium gave better results than 15 other culture media used for the direct plating of Enterococcus.
Testing Results
Enterococcus faecalis (ATCC 19433)Growth, pink-red colonies.
Escherichia coli (ATCC 25922)Inhibited.
