This paper introduces a mild extraction method for Gram-positive bacterial cell wall glycopolymers that preserves structural integrity and yields 17 distinct glycopolymers from 11 species.

The paper integrates holo-omic data from porcine hosts and gut microbiomes to predict host-microbiome interactions, identifying both known and novel relationships.

This paper uses β-galactosidase to convert raffinose oligosaccharides into β-GOS, which are less fermentable by some gut microbes but still usable by beneficial bacteria.

This paper identifies two carbohydrate esterases from Bacteroides cellulosilyticus that work together to deacetylate complex β-mannans, with one showing specificity for 2-O-acetyl groups and the other acting broadly on diverse substrates.

This study identifies high molecular weight polysaccharide contaminants in yeast extract that affect exopolysaccharide (EPS) purity and structural analysis, showing their removal via ultrafiltration.

The paper develops an in vitro model to study porcine caecal microbiota response to β-mannan and finds similar microbial responses to in vivo trials with some taxa showing greater changes in vitro.

The paper describes a pilot-scale process to extract raffinose oligosaccharides from pulse protein concentrates using mild acid extraction and filtration, resulting in enriched RFO fractions and slightly higher protein content.

This study evaluates microbiota-directed fibers (MDFs) in Atlantic salmon diets, finding negligible effects on gut microbiome and host physiology, but identifying potential endogenous lactic acid bacteria for future MDF strategies.
