TEST KIT AND METHOD FOR THE QUANTITATIVE DETERMINATION OF COLIFORM BACTERIA AND E. COLI

摘要

A test kit and method particularly for the quantitativedetermination of total coliform bacteria and E. coliparticularly in large volume test samples, such as water,wherein the media includes an agent which changes color anda gelling agent which reacts or provides in situ with thetest sample a semi-solid broth or media for incubation,thereby restricting the mobility of the growth bacteria andpermitting a quantitative count of the separate, coloredbacteria colonies.
