Modulatory Effects of Boletus edulis on the Gut Microbiota in Atlantic Salmon Utilizing an Artificial Teleost Gut Model

Here, we investigated the prebiotic effect of Boletus edulis extract on the gut microbiota of farmed Atlantic salmon via an in vitro gut model (SalmoSim). Notable changes in the production of short-chain fatty acids and microbial diversity were observed upon the addition of Boletus edulis extract. In particular, a change toward better fiber fermentation was suggested by the decreasing concentrations of ammonia and increasing levels of acetate and propionate.
