Hello Dear members of forum,
Do anyone have suggestions regarding the microbiological method validation for probiotics. My product contains four bacterial strain (L.acidophilus, L. rhamnosus,S.thermophilus, L.bulgaricus) for analyses I use two dilutions 6 and 8, according specification product contains 2*109 probiotic bacterial count. I’m confused, I don’t know what where to start, should I use standard bacterial strains of lactobacteria for investigation and use such approach as we have during the microbiological method validation. If someone have experience in this filed or some advice, I’ll be glad to share your opinions.
