Thermo Scientific™ Lauryl Tryptose Broth (1X) w/DT

Description

• Detect coliforms in water, wastewater, and foods using Thermo Scientific™ Remel™ Lauryl Tryptose Broth (LST Broth)
• Lauryl Tryptose Broth is recommended by the American Public Health Association (APHA), AOAC International (AOAC) and the U.S
• Food and Drug Administration (USFDA) for the detection of coliforms in water, wastewater, and foods 1-4
• The production of gas in Lauryl Tryptose Broth serves as a presumptive test for the presence of coliforms in water and foods
• Mallman and Darby developed Lauryl Tryptose Broth 5,6 and they evaluated a variety of wetting agents and determined that addition of sodium lauryl sulfate to selective media produced the best results for the detection of the coliform group
• Recommended by the APHA, AOAC and USFDA for the detection of coliforms in water, wastewater, and foods 1-4 Selective medium - Selective agent sodium lauryl sulfate inhibits many organisms other than coliforms Ready-to-use - Convenience of prepared media
• Easy to interpret - Turbidity in the broth and gas bubbles in the inverted Durham tube indicates positive fermentation reaction: Positive test - Turbidity with gas production within 48 hours Negative test - Turbidity with no gas production within 48 hours This medium contains casein peptone that supplies nitrogen, carbon, and sulfur required for the bacterial growth
• Sodium chloride provides essential electrolytes and maintains osmotic equilibrium
• Lactose is the carbohydrate source fermented by coliforms
• Dipotassium phosphate and monopotassium phosphate present in the medium serve as buffering agents.
