Eosin-Methylene Blue Agar

Eosin-Methylene Blue Agar (EMB Agar) is a widely used selective and differential culture medium designed for the isolation, detection, and differentiation of enteric bacteria, particularly Escherichia coli (E. coli), in clinical, food safety, environmental, and microbiological testing laboratories. EMB Agar supports the rapid identification of lactose-fermenting and non-lactose-fermenting microorganisms, making it an essential medium for coliform testing and pathogen screening.

The carefully balanced formulation contains peptone, lactose, eosin Y, and methylene blue, which inhibit most Gram-positive bacteria while promoting the growth of Gram-negative enteric organisms. Strong lactose fermenters such as E. coli typically produce dark colonies with a characteristic metallic green sheen, a key indicator in microbial identification and water quality testing.

EMB Agar is widely used in food microbiology, environmental monitoring, clinical diagnostics, coliform detection, bacterial isolation, and quality control laboratories. Manufactured by Babio Biology, a leading Chinese manufacturer of microbiological culture media, this premium-quality medium delivers consistent performance and reliable results for laboratory professionals worldwide.
