Product manual
Product name:LST Broth
Product usage: Used for the determination of coliform and Escherichia coli.
Test principle
Tryptone is used as a nutrient in the medium to provide nitrogen sources, vitamins, amino acids and growth factors needed for cell growth. Lactose provides carbon source for cell growth of bacteria. Sodium chloride maintained osmotic pressure balance. Phosphate provides a relatively stable acid-base buffer system for bacterial growth. Sodium lauryl sulfate inhibits the growth of non-coliform bacteria.
