Uses: For rapid detection of E. coli and E. coli in food, water, milk, ice cream and meat products. E. coli is blue to purple, E. coli is red.
Escherichia coli/coliform coloring medium (plate)Operation steps
1. Prepare sample solutions according to national standards, SN standards, FDA standards, or other methods.
2. Take 1 ml of the sample solution and add it to the color development medium cooled to 45-50 ° C to mix well or apply it on a plate.
3. Cultivate at 36 ° C for 18-24 hours, select a plate with 30-200 colonies, and count the typical coliform and Escherichia coli colonies that appear on the plate. Typical colony of Escherichia coli is blue to purple, coliform coliform is pink, and other bacteria are colorless or yellow; total coliform coliform = blue colony + purple colony + pink colony, Escherichia coli = blue colony + purple colony;
4. SuspiciousEscherichia coliThe colonies can be inoculated on a nutrient agar plate, incubated at 36 ° C for 12-16 hours, and a single colony can be selected for a full set of biochemical tests for E. coli (the company has 4 kinds of biochemical identification tube sets x 4 sets).
Limitations of the method
This medium identifies Escherichia coli/Escherichia coli. In rare cases, false positives may occur, but no false negatives may occur. Sometimes additional tests may be required.
typical features
The typical colony of Escherichia coli is blue to purple, the coliform is pink, and other bacteria are colorless.
Attention
This medium is for laboratory use only.
