Zusammenfassung: | A method of enumerating gas-producing coliform bacteria present in a cultured dairy product is provided. The method can comprise forming a mixture that comprises a predefined quantity of the dairy product and a predefined volume of a diluent; inoculating a thin film culture device with the mixture to form a hydrogel comprising a nutrient medium for growing coliform bacteria, an effective concentration of lactose, and an effective concentration of MOPS; incubating the inoculated thin film culture device under conditions that facilitate growth of a coliform bacterium; and identifying and counting a gas-producing colony present in the inoculated culture device. |
