LAURYL SULPHATE BROTH (LAURYL TRYPTOSE BROTH) (VEG.)

Lauryl Tryptose Broth (Veg) is prepared by replacing Tryptose with Veg Hydrolysate No.1 which is free from BSE/TSE risks. Lauryl Tryptos Broth (Veg) is the modification of Lauryl Tryptose Broth which was formulated by Mallmann and Darby and is recommended by APHA for the presumptive detection of coliforms in water, effluent or sewage by MPN testand for the detection of coliforms in foods. This medium, like the conventional medium is designed to get rich growth and substantial amount of gas from small inocula of coliform organisms. Aerobic spore bearers are completely inhibited. Cowls showed that sodium lauryl sulphate gave selectivity to the medium for coliform bacteria.
The Lauryl Tryptose (Lauryl Sulphate) Broth (Veg) gives a higher colon index than the confirmatory standard methods media and the gas production served not only as a presumptive test but also confirmatory of the presence of the coliforms for routine testing of water.

for detection and enumeration of coliform bacteria in water, dairy products and other foods
