Polysaccharide breakdown products drive degradation-dispersal cycles of foraging bacteria through changes in metabolism and motility

This study shows that marine bacteria switch from polysaccharide degradation to motility when exposed to breakdown products, enabling dispersal to new nutrient sources.

Interspecies interactions determine growth dynamics of biopolymer degrading populations in microbial communities.

This study investigates how consumer cells affect the growth and spatial distribution of biopolymer-degrading microbes in marine communities, revealing their impact on enzyme production and community dynamics.

Intestinal Bacteroides Modulates Systemic Inflammation and the Microbial Ecology in a Mouse Model of CF: Evidence for Propionate and other Short Chain Fatty Acids Reducing Systemic Inflammatory Cytokines

This study shows that Bacteroides in CF patients reduces systemic inflammation via propionate and alters microbial ecology in a mouse model of CF.

Turnover in life strategies recapitulates microbial succession on synthetic marine particles

The paper identifies two distinct microbial community classes on synthetic marine particles, shaped by environmental selection and facilitation, with distinct metabolic traits.

Multicellular behavior enables cooperation in microbial cell aggregates

The paper shows that bacterial behavior enables cooperation in cell aggregates by overcoming resource gradients through structural adaptations.

Pseudomonas aeruginosa Can Inhibit Growth of Streptococcal Species via Siderophore Production

This study shows that Pseudomonas aeruginosa inhibits growth of Streptococcus species by producing siderophores that compete for iron.

Modular assembly of polysaccharide-degrading microbial communities in the ocean

This study shows that ocean polysaccharide-degrading microbial communities assemble in a modular fashion, with distinct primary degrader and broad-niche consumer modules, and validates this model using synthetic particles.
