Lauryl Tryptose Broth is used for the detection of coliform bacteria in water and wastewater.
Product Summary and Explanation
production faster. Sodium Lauryl Sulfate produced the best results for inhibition of organisms other than coliforms.5 Lauryl Tryptose Broth, abbreviated as LTB, is used in the presumptive phase of the Standard Total Coliform Fermentation Technique in the examination of water,2 and coliform detection of foods.3,4,6
Principles of the Procedure
Tryptose provides nitrogen, vitamins, minerals, and amino acids in Lauryl Tryptose Broth. Lactose is the fermentable carbohydrate for coliforms. Potassium Phosphates are the buffering agents, and Sodium Chloride is used to maintain the osmotic balance of the medium. Sodium Lauryl Sulfate is the selective agent used to inhibit non-coliform organisms.
