Abstract
A broth medium for the detection of Escherichia coli in water samples, i.e., sewage specimens, and process for inoculation and incubation of said broth to conduct satisfactory detection tests. The medium employs para-coumaric acid and acetazolamide to inhibit growth of unwanted microorganisms and thus greatly reduces false positive test results.
