A completely randomized experimental design was conducted to evaluate the effect of coadministration of Lpb. fabifermentans and inulin/agave fructans mixtures on gut microbiota. The results showed that the combination of fructan mixtures and Lpb. fabifermentans significantly decreased glucose, cholesterol, and triglycerides levels, and improved short-chain fatty acids concentration throughout the gastrointestinal tract. It also promoted an increase in the abundance of beneficial intestinal microbiota. Therefore, the inclusion of fructan mixtures in combination with Lpb. fabifermentans could be a good alternative for the development of functional foods that enhance consumer health.
A completely randomized experimental design was conducted to evaluate the effect of the coadministration of Lactiplantibacillus fabifermentans (Lpb. fabifermentans) and inulin/agave fructans mixtures on gut microbiota of healthy Wistar rats. Inulin, Agave salmiana fructans or fructan mixtures (1:1) at 12.5 % w/w, and Lpb. fabifermentans at 109 CFU/mL/day were used in the rats' diet for 35 days. Biochemical parameters, short-chain fatty acids (SCFA), structural changes and the bacterial abundance in rats' cecum were evaluated. A significant decrease (p < 0.05) in glucose, cholesterol and triglycerides levels with fructan mixtures combined with Lpb. Fabifermentans was observed. The weight of the small and large intestines, and cecum was higher than the control; no changes were observed in the heart, liver, spleen and kidneys. SCFA concentration mainly, propionate and butyrate was improved (p < 0.05) throughout the gastrointestinal tract in all treatments. Finally, the administration of Lpb. fabifermentans alone or combined with the fructan mixtures promoted an increase in the abundance of cecum intestinal microbiota: Lactobacillus, Bifidobacterium, Prevotella, Blautia, Faecalibacterium, Butyricimonas, Coprococcus, Akkermansia, Methanobrevibacter, Adlercreutzia, Collinsella, Odoribacter, and Roseburia. The inclusion of fructan mixtures in combination with Lpb. fabifermentans could be a good alternative for the development of functional foods that enhance consumer health.
