Separating extracellular from intracellular fecal metabolites exposes cross-feeding architecture in the gut: exploring metabolite partitioning and ecological associations

The gut microbiota forms a complex ecosystem through metabolic interdependence (cross-feeding). However, conventional fecal metabolomics typically quantifies only total metabolite pools, making it difficult to distinguish extracellular-enriched metabolite pools from predominantly...
