Title (EN) NOVEL AND IMPROVED METHOD FOR DETERMINATION OF E. COLI IN WATER
(FR) PROCEDES NOUVEAUX ET AMELIORES DE DETERMINATION DE E. COLI DANS L'EAU
Abstract:
(EN) A method for determination of $i(E. Coli) in water samples. The method is based on simultaneous measurement of indole production and lactose utilization, two distinct traits specific to $i(E. Coli). A new medium contains essentially $g(b)-glucuronidase, tryptophan, and tryptose.

Le procédé est basé sur la mesure simultanée de production d'indole et l'utilisation de lactose, deux traits distincts spécifiques de $i(E. Coli). Un nouveau milieu contient essentiellement de la $g(b)-glucuronidase, du tryptophane, et du tryptose.
