“…preferentially use these organic acids as a carbon source for butyrate production. An increase in the abundance of the Mediterranneibacter genus as characterized by the FMPF and FMB formulations was also reported by Ruiz-Rico et al [ 102 ] when the impact of different modes of presentation of chitosan were assessed. Additionally, the abundance of Mediterranneibacter faecis is considered a biomarker for improving health due to its capacity to produce several short-chain fatty acids.…”

The effect of putative probiotic fermented milk (FM) with buriti pulp (FMB) or passion fruit pulp (FMPF) or without fruit pulp (FMC) on the microbiota of healthy humans was evaluated. FM formulations were administered into a simulator of the human intestinal microbial ecosystem (SHIME®) to evaluate the viability of lactic acid bacteria (LAB), microbiota composition, presence of short-chain fatty acids (SCFA), and ammonium ions. The probiotic LAB viability in FM was affected by the addition of the fruit pulp. Phocaeicola was dominant in the FMPF and FMB samples; Bifidobacterium was related to FM formulations, while Alistipes was associated with FMPF and FMB, and Lactobacillus and Lacticaseibacillus were predominant in FMC. Trabulsiella was the central element in the FMC, while Mediterraneibacter was the central one in the FMPF and FMB networks. The FM formulations increased the acetic acid, and a remarkably high amount of propionic and butyric acids were detected in the FMB treatment. All FM formulations decreased the ammonium ions compared to the control; FMPF samples stood out for having lower amounts of ammonia. The probiotic FM with fruit pulp boosted the beneficial effects on the intestinal microbiota of healthy humans in addition to increasing SCFA in SHIME® and decreasing ammonium ions, which could be related to the presence of bioactive compounds.

“…Specifically, the non-covalent conjugation of polysaccharide to protein, including the electrostatic interaction, hydrophobic force, hydrogen bonds, may strengthen the functions of the proteins and provide an opportunity to stabilize bioactive compounds [11] . Chitooligosaccharide, a naturally cationic amino oligosaccharide, has a high antibacterial property and has a good biocompatibility [12] , [13] . Many attentions have been received owing to the non-toxic feature and the cationic conjugation role of chitooligosaccharide to protein.…”
