Principle
- Lauryl sulfate broth is composed of tryptose, lactose, potassium phosphate dibasic and monobasic, sodium chloride, and sodium lauryl sulfate.
- Tryptose provides nitrogen and amino acids. Lactose is a fermentable carbohydrate. Potassium phosphates are buffering agents. Sodium chloride maintains osmatic balance.
- Sodium lauryl sulfate inhibits non-coliforms. The selectivity of the medium is provided by lactose and sodium lauryl sulfate.
