    Abstract / Zusammenfassung

    Aims and workpackage:
    - To clarify on statistical basis, if the two commercial availiable media (TPY and TOS) both in combination with MUP are suited for the enumeration of bifidobacteria occuring in sour milk produkts

    - To investigate if there is a difference in the growth performance of the local chosen probiotic yogurt products containing bifidobacteria in addition to S. thermophilus and L. acidophilus

    - To find out if the commercial available TPY medium and the TOS medium are suited for routine purposes

    - Experimental design strategy outlined by H. Weiss, W. Kneifel & U. Zitz

    - Bifido trials performance in January until March 2005

    - Preparatory trials at BOKU/Vienna in 2004/2005

    * Experimental design:
    - 3 different local available yogurts containing
    Bifidobacteria, S. thermophilus and L. acidophilus selected by each of the participating laboratories

    - 6 participating laboratories

    - Analyst performance of all the participating laboratories

    - Main trial with 2 separated dilution series performed on both media and within one day

    - Statistical evaluation
