Product introduction
For Escherichia coli, Coliform group, fecal coliform group primary fermentation test and E. coli count
Principle
Pepeptone was used as the basic nutrient to provide nitrogen and carbon source for cell growth. Lactose as a fermentable carbohydrate; Sodium lauryl sulfate can inhibit the growth of non-coliform bacteria. Sodium chloride was used to maintain the osmotic pressure balance of the system. Phosphate was used as a buffer to maintain the pH of the medium system.
