General description

Lauryl sulfate Broth (LSB) is a selective media, assortedly used for coliform determination. LSB serves to examine the quality of water, dairy products and foodstuffs.

Application

Lauryl sulfate Broth has been used for E.coli determination.
Selective medium acc. to Mallmann and Darby (1941) for the presumptive testing for coliform and their selective enrichment in the examination of water, dairy products and food.
Recommended by the "Schweizerisches Lebensmittelbuch" 5th ed., chapter 56A.
The difference to Cat. No. 17349 is that Casein Peptone is used (instead of Tryptose)

Preparation Note

Dissolve 35.6 g in 1 litre distilled water. Distribute to convenient flasks. Sterilize by autoclaving at 121°C for 15 minutes.
