The paper quantifies chemical fluxes between gut microbiota and host by identifying measurable host parameters that influence flux magnitudes.

The paper develops a high-resolution mass spectrometry method to quantify nitrogen-containing compounds across diverse systems, revealing microbiome impacts on nitrogen distribution in mice.

The paper shows how spatial structure in the gut microbiota emerges through bacterial growth in the matrix of gut content.

The paper tests how gut microbiome variation affects Escherichia coli growth across human samples, finding interspecies interactions influence growth outcomes.

The paper introduces a transcriptomic marker gene-based classifier to predict bacterial growth states across species in microbial communities.

The paper quantifies the metabolic flux of fermentation products from the gut microbiota, showing it varies with diet but not microbiota composition.

This paper demonstrates the use of secondary electrospray ionization mass spectrometry to non-invasively monitor gut microbiota metabolism in live mice.

The paper studies phenotypic switching in Salmonella by analyzing fliC promoter dynamics, finding that oscillatory transitions occur due to regulatory delays rather than noise-driven transitions.
