Genome-wide sweeps create ecological units in the human gut microbiome

Another fun collaboration with Martin Polz’s lab. Annie found a way to identiy genome-wide selective sweeps from isolate genomes, and identifies populations that swept through the globe. These populations are more strongly associated than traditional species definitions with host states such as disease.

Samira and Elle join for a research internship

We are very glad to welcome both Samira and Elle to the lab. They will be working together with Lior about predicting carbon decomposition phenotypes from genomes.

Human milk oligosaccharide mediates mutualism between Escherichia coli and Bifidobacterium bifidum.

David Seki, currently a postdoc with Michi Wagner, found a mutualism that may explain E. coli’s prevalence in infant guts. David found that E. coli and B. bifidum can form a mutualism where E. coli supplies cystein to auxotrophic Bifidobacteria, and they in turn feed it fucose left over from extracellular HMO degradation.

Microbial iron oxide respiration coupled to sulfide oxidation.

A nice collaboration with Songcan from Alex Loy’s group just down the corridor. Songcan found a new microbial sulfur metabolic pathway that is globally widespread and can be a large contributor to the sulfur cycle.
