Lauryl Sulfate Broth, LSB
 
Catalog Number: AS-1266
 
Lauryl Sulfate Broth (LSB), also called Lauryl Tryptose Broth (LTB), is a selective enrichment medium. It is used for the enumeration and presumed detection of coliform bacteria. Coliforms are facultative anaerobic, gram-negative microbes that digest lactose to create gas and acid. To supply vital nutrients, LTB includes tryptose, while sodium lauryl sulfate functions as a selective agent to prevent the growth of non-coliform organisms. Durham tubes show that the medium’s buffered nature promotes coliforms’ quick generation of gas. LSB is used in microbiological analyses of food, dairy, and water.
