The Broad Institute-OpenBiome Microbiome Library

The BIO-ML is a comprehensive biobank of human gut bacteria: a library of 7,758 bacterial isolates with 3,632 paired genome sequences. This library covers most of the phylogenetic diversity found in the gut of OpenBiome FMT donors, contains extensive strain diversity, and is available to the research community. 

A high resolution multi-omic database containing longitudinal 16S, metagenomic and metabolomic data provides an additional layer of context to the BIO-ML gut bacterial isolates and genomes. 


Our Diversity Box contains bacterial isolates belonging to 106 species (1 strain from each species). 

$5,000 / box

Our Mini Diversity Boxes contain several strains of the same bacterial species (coming soon).

$1,000 - $5,000 / box

Contact us to purchase individual strains or make your Personalized Diversity Box.
