Annotation of standard text ČSN ISO 9232 (571421):

Uvedená norma specifikuje testy pro identifikaci charakteristických mikroorganismů v jogurtu na základě jejich morfologických, kultivačních a fyziologických vlastností.

Popisuje postup isolace kolonií, který spočívá z výběru kolonií z misek použitých pro stanovení počtu kolonií, zaočkování do příslušné tekuté kultivační půdy, kultivace v inkubátoru regulovaném na 37 °C po dobu 24 hodin při atmosférických podmínkách. Následují identifikační testy, které se porovnají s hlavními atributy L. delbrueckii subsp. bulgaricus a S. thermophilus.

Metoda je určena pro kmeny izolované z jogurtů, ve kterých jsou přítomny charakteristické živé mikroorganismy.
