Abstract
Aim: To demonstrate the ability of a probiotic supplement (BIOHM) to disrupt pathogenic gastrointestinal biofilms, thus enhancing nutrient absorption. Methods: A filter insert model using Caco-2 cells to mimic an intestinal monolayer was employed to determine the ability of BIOHM to disrupt a mixed species (Candida tropicalis, Escherichia coli and Serratia marcescens) biofilm known to occur in patients with Crohn’s disease. Penetration of vitamin C and casein as representative of vitamins and proteins, respectively, was then measured. Results: Application of BIOHM led to a significant increase in casein penetration through the Caco-2 cell epithelial monolayer in the absence of biofilms (p value<0.0001). Additionally, the combination of mixed species biofilms grown on a Caco-2 cell monolayer with BIOHM filtrate resulted in higher penetration of vitamin C and casein through the monolayer compared to untreated controls. Conclusion: Our in vitro data indicates that the combination of ingredients in the BIOHM probiotic may enhance nutrient permeability, thus leading to increased overall absorption of proteins and vitamins.
