What differentiates strains of Peregrinibacteria?
In this manuscript, we present the first ever strain-resolved complete genomes from metagenomics for five members of the bacterial phylum Peregrinibacteria, that were sampled from filtered groundwater obtained from an aquifer adjacent to the Colorado River near the town of Rifle, CO, USA. Importantly, strain-variation in these bacteria is not observed in their ribosomal rRNA, rather it manifests primarily in large extracellular proteins which may function in attachment to other cells.
