Description

【Product name】

Common name: Eosin Methyl Blue Agar (EMB)
English name:Eosin-Methylene Blue Agar

【Model specifications】

250g/Bottle

【Intended use】
Used to isolate Gram negative gut bacteria, especially coliform and fecal coliform groups.
【Verification principle】
Culture medium is a mixed nutritional product prepared by artificial methods, specifically for microbial cultivation, separation, identification, research, and preservation. The peptone contained in eosin blue agar provides carbon and nitrogen sources, vitamins, and growth factors; Yihong and Meilan are pH indicators that can also inhibit the growth of Gram positive bacteria; Potassium hydrogen phosphate acts as a pH buffer; Agar is a coagulant for the culture medium; Lactose is a fermentable sugar.
【Composition】
Peptone, dipotassium hydrogen phosphate, lactose, agar powder, indicator, and other culture medium materials are milled and packaged.
【Usage method】

After pre-treatment according to GB standards, the samples were inoculated into a culture medium at 36 ± 1 ℃ for 18-24 hours, and the results were observed.
【Inspection results】
Escherichia coli grows well, with black colonies and a metallic luster; Salmonella typhimurium grows well, with colorless and translucent colonies; The growth of Staphylococcus aureus is inhibited.
【Note】
1. This culture medium is only used for scientific research.
2. The collected specimens must be inoculated and cultured as soon as possible to ensure accurate results.
3. The specimens used and their cultivation waste should be considered as potentially infectious substances and should be disposed of in accordance with the operating standards of infectious disease laboratories.
