This study develops and validates a biophysical model showing that constant ratios of cytoplasmic and membrane protein densities regulate Escherichia coli cell geometry through proteome partitioning and ribosome content.

The paper studies intra-species diversity in microbial communities by competing gut strains, finding strong selection and coexistence due to biotic interactions.

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