| Resumo(s): | Xylooligosaccharides (XOS) are emergent prebiotics exhibiting high potential as food ingredients. In this work, in vitro studies were performed using human fecal inocula from two healthy donors (D 1 and D2) to evaluate the prebiotic effect of commercial lactulose and XOS produced in a single-step by recombinant Bacillus subtilis 3610. The fermentation of lactulose led to the highest production of lactate (D1: 33.7±0.5mM; D2:19.7±0.3mM) and acetate (D1: 77.5±0.6mM; D2: 81.0±0.7mM), while XOS led to the highest production of butyrate (D1: 9.0±0.6mM; D2: 10.5±0.8mM) and CO2 (D1: 8.92±0.02mM; D2: 11.4±0.3mM). Microbiota analysis showed a significant decrease in the relative abundance of Proteobacteria for both substrates and an increase in Bifidobacterium and Lactobacillus for lactulose, and Bacteroides for XOS. |
