Probiotic bacteria - studies on identification and viability of probiotics


Prolab company performs studies on identification and viability of active ingredients of probiotics according to WHO/FAO guidelines and its own laboratory practice procedures based on the norm PN-EN ISO 7218:2008 „Microbiology of food and animal feeding stuffs” together with the norm PN-ISO 15214:2002 „Microbiology of food and animal feeding stuffs. Horizontal method for the enumeration of mesophilic lactic acid bacteria. Colony-count technique at 30°C. General requirements and microbiological studies guidelines”.

Probiotic bacteria are identified using phenotyping and genotyping methods. It is also possible to confirm whether the strains contained in the probiotic preparation are identical with the reference strains (PFGE method). Viability studies are done based on standard colony counting methods, with strains being cultured on appropriate culture media, as well as modern tools that Prolab offers, such as determination of active vs. dead cells in fluorescence microscopy. Prolab also offers testing of the strains contained in preparations for probiotic properties according to WHO/FAO guidelines. These are esp. antimicrobial antagonism studies, lactic acid bacteria resistance to gastric juice and bile salts as well as studies on the adherence to epithelial cells.
