Lauryl Tryptose Broth (Dehydrated)

Detect coliform organisms in water, waste water and dairy products with selective Thermo Scientific™ Oxoid™ Lauryl Tryptose Broth (Dehydrated), while conforming to the formula detailed by American Public Health Association. Lauryl Tryptose Broth is designed to promote a rich growth and copious gas production from small inocula of coliform organisms.

Use Lauryl Tryptose Broth for detection of coliform organisms in water, wastewater and dairy products for the presence of indicator groups such as coliforms. Besides safety, indicator groups provide a measure of food quality and spoilage potential. One of the most common groups of bacteria employed as indicator organisms by the food industry are the coliforms, which can be regarded as a subgroup within the Enterobacteriaceae

• Selective: sodium lauryl sulphate selects for coliform group
• Recommended by APHA¹ for the Most Portable Number (MPN) presumptive test of coliforms in water, effluent or sewage.

The advantage of using Lauryl Tryptose Broth is that, in addition to giving the fermentation reaction typical of MacConkey Broth, it can also be tested for the presence of indole.

The APHA¹ recommend that Lauryl Tryptose Broth should be used for the Most Probable Number (MPN) presumptive test of coliforms in waters, effluent or sewage as a confirmatory test of lactose fermentation with gas production for milk samples (APHA²) and for the detection of coliforms in foods (APHA³ ).
