Strong adhesive seal with cross-cut windows. This seal is peelable and suitable for 96 well plates (auto samplers, HPLC, sequencers).
For the determination of Escherichia coli in drinking water and its source water by multiple tube fermentation method.
MUG permits the rapid detection of Escherichia coli when the medium is observed for fluorescence using a UV light. MUG is hydrolyzed by the enzyme β-glucuronidase which is produced by E. coli to yield a fluorescent end product 4- methylumbelliferone. Trypticase provides the essential nutrients. Lactose is the fermentable carbohydrate. Sodium chloride maintains the osmotic equilibrium. The medium has a strong buffering system to control the pH in the presence of fermentative action. The bile salts inhibit gram-positive bacteria especially the Bacillus species and faecal Streptococci.

Weigh 37g of dry powder of this product, add 1L of distilled water or deionized water, stir, heat and boil until
completely dissolved, sterilize at 115℃ for 20min, cool to room temperature and set aside.
The following quality control strains were inoculated and cultured at 44.5℃±0.5℃ for 24h. The results are as follows:
| Quality control strains | Growth |
| Escherichia coli ATCC25922 | Blue-white fluorescence is produced under 366nm UV light |
| Salmonella typhimurium ATCC14028 | No fluorescence under 366nm UV light |
| Enterococcus faecalis ATCC29212 | Clear, no fluorescence |
2-30℃，Keep container tightly closed, avoid direct sunlight.
Use before expiry date on the label.
1. When weighing the dehydrated medium, please wear masks to avoid causing respiratory system discomfort
2. Keep container tightly closed after using to prevent clumping.
Microbiological contamination was disposed by autoclaving at 121°C for 30 minutes.
