Explore the GMbC Collection

The Global Microbiome Conservancy (GMbC) Collection at OpenBiome—the most globally representative and accessible microbiome collection of its kind—is radically expanding scientists’ view of the human microbiome. GMbC Starter Kits are now available for nonclinical, noncommercial research.

What is in the GMbC Collection at OpenBiome?

The Global Microbiome Conservancy (GMbC) collection contains stool samples from more than 1,300 individuals over 40 diverse, underrepresented communities. From these samples the GMbC consortium has prepared

  • 1,000+ metagenomic surveys
  • 10,000 genome-sequenced bacterial cultures

The collection represents more than 450 species groups and covers a wide range of bacterial taxa across multiple phyla, including from some groups that were previously considered as unculturable.
