Assessing probiotic features in bacterial strains

Introduction

The requisites of probiotics represent a key factor as indicated in the “Indications for use in food products and food supplements of probiotic micro-organisms (bacterial and/or yeasts), which have long been used to promote the balance of intestinal microflora” (GUIDELINES ON PROBIOTICS AND PREBIOTICS, Revised in March 2018, Ministry of Health)

How do I know if my microbial strain is probiotic?

Strategy

You need to characterize your microbial strains through a package of in-vitro accredited methods : the absence of transmissible antibiotic resistances, ability to adhere to human gut cells and to survive simulated stomach and intestinal passage. Accreditation of analytical methods assures the repeatibility and riproducibility of the results.
