General description
Lauryl Sulfate Broth, developed by Mallmann and Darby in 1941, is aselective medium used for the presumptive testing and selective enrichment ofcoliform bacteria in water, dairy products, and foodstuffs. The medium isformulated with tryptose instead of casein, providing essential nitrogen,carbon compounds, vitamins, and amino acids for bacterial growth. Lactoseserves as fermentable sugar, while sodium lauryl sulfate and bile salts inhibitnon-coliform organisms, including gram-positive bacteria such as bacilli andfecal Streptococci. Sodium chloride maintains osmotic balance, and potassiumphosphates stabilize the pH during lactose fermentation.
Application
根据Mallmann和Darby（1941）制备的选择性培养基可用于进行大肠菌群的推定性检测及其在水、乳制品和食品检测中的选择性富集。
