The quantification of unviable/inactivated probiotics is a critical issue that conventional microbiological techniques can not satisfy.
How I can assess quickly the concentration in viable and unviable cells in my probiotic powder/sample?
AAT developed an integrated system to couple different analytical methods to assess viabl and dead bacteria in a powder sample: analyse your samples by flow cytometry (accredited method ISO 19344:2015) together with real-time quantitative PCR. Accreditation of analytical methods assures the repeatibility and riproducibility of the results.
