Webof acid is used to differentiate E. coli from Enterobacter aerogenes. Both organisms initially produce organic acids. When E. coli is grown in glucose broth, mixed acids (lactic, formic and acetic) are formed until a pH of 4-5 is reached. In contrast, E. aerogenes converts organic acids to nonacidic endproducts such as 2,3-
