EMB AGAR - Names and Identifiers
EMB AGAR - Introduction
Eosin methylene blue agar (EMB) is a commonly used microbial culture medium and selective agar plate medium. It is used to isolate and identify intestinal bacteria, especially Escherichia coli and Enterococcus faecalis.
The preparation method of EMB agar includes dissolving agar in water and heating, and then adding eosin (Eosin Y) dye and methyl blue (Methylene Blue) dye and maltodextrin (Lactose) as a carbon source.
The characteristic of EMB agar is that it distinguishes different colonies through the change of color of different agar. E. coli forms metallic green or metallic dark purple colonies, while other intestinal bacteria form colorless colonies. In addition, EMB agar can also inhibit the growth of bacteria other than E. coli, which can better selectively cultivate target bacteria.
EMB agar is widely used in microbiology laboratories, especially in the isolation and identification of intestinal bacteria, environmental monitoring, and food and water quality testing. It can help researchers quickly screen and identify the target strains, and perform quantitative analysis.
For safety information, EMB agar is a chemical and should be used with caution. Wear appropriate protective equipment during operation to avoid contact with skin, eyes or mouth. After use, waste should be properly disposed of and disposed of in accordance with relevant regulations. Before use, the material safety data sheet (MSDS) of the product should be read carefully to understand the specific safe handling and storage requirements.
