Agaricus bisporus, an edible mushroom, is grown and consumed worldwide for its delicious taste and multiple health benefits. A. bisporus polysaccharides (ABP) are the main bioactive ingredient of the mushroom that confers health benefits. In this study, we prepared and characterized ABP, and the digestion, fermentation prosperities, and the effect of ABP on gut microbiota were detected via in vitro simulated digestion and gut microbiota fermentation. The results showed that during the simulated digestion process, the molecular weight of ABP was unchanged, and no free monosaccharide was produced, indicating that ABP could not be digested completely. However, after the fermentation, gut microbiota degraded and utilized ABP, which produced short-chain fatty acids and caused a decrease in pH value. Meanwhile, ABP modulated the gut microbiota composition by increasing the abundance of beneficial bacteria. The results suggested that ABP is a promising food component with prebiotic potential.

Microbiota in the gastrointestinal tract (GIT) consisting of the rumen and hindgut (the small intestine, cecum and colon) in dairy calves play a vital role in their growth and development. This review discusses the development of dairy calf intestinal microbiomes with an emphasis on the impact that husbandry and rearing management have on microbiome development, health and growth of pre-weaned dairy calves. The diversity and composition of the microbes that colonize the lower GIT (small and large intestine) can have a significant impact on the growth and development of the calf, through influence on nutrient metabolism, immune modulation, resistance or susceptibility to infection, production outputs and behaviour modification in adult life.

Prebiotics, traditionally linked to gut health, are increasingly recognized for their systemic benefits, influencing multiple organ systems through interactions with the gut microbiota. Compounds like inulin, fructooligosaccharides (FOS), and galactooligosaccharides (GOS) enhance short-chain fatty acid (SCFA) production, benefiting neurocognitive health, cardiovascular function, immune modulation, and skin integrity. Advances in biotechnology, including deep eutectic solvents (DES) for extraction and machine learning (ML) for personalized formulations, have expanded prebiotic applications.

Ulcerative colitis is a long-term inflammatory colon illness that significantly affects patients quality of life. Traditional medicines and therapies often come with challenges such as side effects, instability, unpredictability, and high costs. This has captured interest in natural products that have huge health benefits.

Unlabelled: In the gut, microRNAs (miRNAs) produced by intestinal epithelial cells are secreted into the lumen and can shape the composition and function of the gut microbiome. Crosstalk between gut microbes and the host plays a key role in irritable bowel syndrome (IBS) and inflammatory bowel diseases, yet little is known about how the miRNA-gut microbiome axis contributes to the pathogenesis of these conditions. Here, we investigate the ability of miR-21, a miRNA that we found decreased in fecal samples from IBS patients, to associate with and regulate gut microbiome function.
