Multicellular group formation as a resource competition strategy for marine bacteria Open
Multicellularity can enhance bacterial resilience and robustness in nature. Traits like access to otherwise inaccessible substrates, increased stress tolerance and predation resistance provide ecological advantages that may scaffold the ev…

Deep sea anaerobic microbial community couples the degradation of insoluble chitin to extracellular electron transfer Open
Chitin is a major structural component of arthropod exoskeletons, and an important carbon and nitrogen source in marine environments. Chitin degradation, which proceeds similarly under both oxic and anoxic conditions, produces chitooligosa…

Deep sea anaerobic microbial community couples the degradation of insoluble chitin to extracellular electron transfer Open
Chitin is a major structural component of arthropod exoskeletons, and an important carbon and nitrogen source in marine environments. In anoxic sediments, its degradation generates chitooligosaccharides and N-acetylglucosamine (GlcNAc), wh…

Antagonism as a foraging strategy in microbial communities Open
In natural habitats, nutrient availability limits bacterial growth. We discovered that bacteria can overcome this limitation by acquiring nutrients by lysing neighboring cells through contact-dependent antagonism. Using single-cell live im…

Metagenome-assembled genomes of <i>Macrocystis</i> -associated bacteria Open
Microbes are important for the development of kelp, but little is understood about the functions encoded by these microbes. Here, we assembled 1,794 metagenome-associated genomes (MAGs) from bacteria that colonize gametophytes of the giant…

Global diversity of enterococci and description of 18 previously unknown species Open
Enterococci are gut microbes of most land animals. Likely appearing first in the guts of arthropods as they moved onto land, they diversified over hundreds of millions of years adapting to evolving hosts and host diets. Over 60 enterococca…
