EC BROTH (VEG.)

This medium is prepared by replacing Casein enzymic hydrolysate and Bile salt mixture with Veg hydrolysate and Synthetic detergent No. I making the medium free of BSE/TSE risks. EC Broth (Veg) is the modification of the medium formulated by Hajna and Perry. This medium, like the conventional medium is used for estimation of Escherichia coli densities from sea water and shellfish as reported by Tennant et al or for confirmation of Escherichia coli from frozen foods and nut meats as used by Fishbein and Surkiewicz. This medium can be used like the conventional medium for use in Most Probable Number (MPN) procedure for examination of water, waste water and foods. It should not be used for the direct isolation of coliforms since prior enrichment in a presumptive medium for optimal recovery of fecal coliform is required.

for selective enumeration of faecal and non faecal coliforms in water
