Niche partitioning by resource size in the gut microbiome
Niche partitioning promotes diversity of the human gut microbiota. However, the molecular basis of resource specialization and niche separation in the gut remains poorly understood. Here we show that ...

Thrilled to share our new work uncovering how membrane transporters determine resource-size preferences in gut bacteria, and showing that deleting a single protein domain can shift a transporter’s preference from long to short fructans. www.biorxiv.org/content/10.1...

Incredibly cool work by @smorenogamez.bsky.social et al, from the ecology to the mechanism and back again. This is Darwin's finches at the microbial scale- how do niches emerge based on resource size in the gut? #MicroSky #microbiome #microbiomesky

Very cool print demonstrating how variation in at TonB-dependent transporter repertoires shapes the ability of Bacteroides and Phocaeicola species to utilize fructooligosaccharides (FOS) of different chain lengths
