Abstract

β-Glucan is a fermentable polysaccharide with prebiotic properties that has been shown to improve metabolic indicators. This study evaluated the effects of spent brewer's yeast β-glucan (BGL) and Lactobacillus acidophilus LA-5 (10⁶ CFU/g) (LA5) alone and in combination (LA5-BGL) on the composition of the fecal microbiome of adults with type 2 diabetes mellitus (T2DM) using the Human Gut Microbial Ecosystem Simulator (SHIME®). Short-chain fatty acids (SCFAs), ammonium ions, and cytokines (IL-6 and IL-10) were measured. BGL, LA5, and LA5-BGL increased (p < 0.05) the richness and diversity of microbial communities in the gut microbiome of individuals with T2DM. All treatments increased (p < 0.05) the abundance of Bacteroides, Alistipes, Lactobacillus, Subdoligranulum, and Acidaminococcus, along with increased (p < 0.05) production of SCFAs and anti-inflammatory cytokine (IL-10) compared to the control group. BGL treatments showed a greater increase in microbial diversity, SCFAs levels (butyric, propionic, and acetic acid), and the anti-inflammatory cytokine (IL-10). LA5 showed the highest decrease in ammonium ion levels. Results indicate that BGL may have a prebiotic and immunomodulatory effect on the fecal microbial community and metabolic indicators in adults with type 2 diabetes mellitus (T2DM). Findings underscore the role of BGL as a prebiotic food.

期刊介绍： Probiotics and Antimicrobial Proteins publishes reviews, original articles, letters and short notes and technical/methodological communications aimed at advancing fundamental knowledge and exploration of the applications of probiotics, natural antimicrobial proteins and their derivatives in biomedical, agricultural, veterinary, food, and cosmetic products. The Journal welcomes fundamental research articles and reports on applications of these microorganisms and substances, and encourages structural studies and studies that correlate the structure and functional properties of antimicrobial proteins.
