Abstract :
[en] Variability in the efficacy, safety, and quality of probiotic formulations depends on many factors, including process conditions used by manufacturers. Developing reliable analytical tools is therefore essential to quickly monitor manufacturing differences in probiotic samples for their quality assessment. Here, multi-strain probiotics from two production sites and countries were investigated by proteomics and physico-chemistry approaches in relation to the protective effect on gut barrier. Proteomic analyses showed differences in protein abundances, identities, and origins of two series of VSL#3 samples from different sites. Even though both formulations were qualitatively similar in thermal and colloidal profiles, significant differences were quantitatively observed in terms of maximum decomposition temperature Tmax (p < 0.05) and phase transition temperature Tm (p < 0.01). Such variability in physical and biochemical features impacts on probiotic functionalities and translates into a differential modulation of gut permeability in mice. Physico-chemical scans provide coherent data with proteomics and represent a new tool for time and cost effective quality control of probiotic-based products.
