Annotation of standard text ČSN ISO 7889 (571420):

Uvedená norma specifikuje metodu pro stanovení počtu charakteristických mikroorganismů v jogurtu pomocí techniky počítání kolonií při 37 °C. Podstatou zkoušky je očkování desetinásobného ředění zkušebního vzorku do půdy MRS pro L. delbrueckii subsp. bulgaricus a do půdy M17 pro S. thermophilus a následné anaerobní kultivaci, počítání a ověření pomocí vhodných testů. Metoda je použitelná pro jogurty, ve kterých jsou přítomny charakteristické živé mikroorganismy.
