Sodium Lauryl Sulfate

Product Details:

• Purpose:
  • LSB is a selective growth medium used for the most probable number (MPN) test of coliforms in water, effluent, or sewage.
  • It acts as a confirmation test for lactose fermentation with gas production.
  • Sodium lauryl sulfate inhibits organisms other than coliforms.
• Composition (per liter):
  • Tryptose: 20.0 g
  • Lactose: 5.0 g
  • Sodium chloride: 5.0 g
  • Dipotassium phosphate: 2.75 g
  • Potassium dihydrogen phosphate: 2.75 g
  • Sodium dodecyl sulfate (lauryl sulfate): 0.1 g
• Performance:
  • LSB allows rich growth and substantial gas production from small inocula of coliform organisms.
  • Aerobic spore-bearers are completely inhibited in this medium.
• Applications:
  • Examination of the quality of water, dairy products, and foodstuffs.
  • Presumptive detection of coliforms in water, effluent, or sewage by the MPN test
