Description
Résumé:Here, the authors tailor an acetylated galactoglucomannan (AcGGM) fibre from spruce wood to specifically enrich Roseburia and Faecalibacterium - beneficial species which have the enzymatic machinery to breakdown the fibre and generate butyrate. They subsequently perform a piglet feeding trial, metagenomics and metaproteomics, together showing that AcGGM-fed pigs exhibit not only increased Roseburia and Faecalibacterium populations with AcGGM-specific mannan-specific esterases, but also secondary metabolic pathways.
