Probiotic Properties of Weissella confusa PP29 on Hibiscus sabdariffa L. Media

To date, there are very few data regarding new efficient probiotics’ development with their own prebiotic substrate. All commercial products contain substrate that was previously purified from external sources and added to the final product. The present study describes Weissella confusa strain fermentations in media different anthocyanin concentrations Hibiscus sabdariffa L., order increase exopolysaccharide (EPS) yield, leading augmented probiotic properties. extracted EPS were characterized by Gel permeation chromatography, Fourier-transform infrared, nuclear magnetic resonance spectroscopy; thermal analysis measurements whole fermented media’s properties evaluated testing low pH bile salt resistance, along hydrophobicity auto-aggregation capacity. anthocyanins increased biomass yields high molecular mass improved nutrient access allowing a good microbial suspension media. confirmed dextran structure provides biocompatibility compared existing literature. Simultaneously, protected cells against control fermentation. These results show culture is suitable for further in-vitro in-vivo studies its activity.
