What is in the GMbC Collection at OpenBiome?

The Global Microbiome Conservancy (GMbC) collection contains stool samples from more than 1,200 individuals in 36 diverse, underrepresented communities. From these samples the GMbC consortium has prepared

  • 1,000 metagenomic surveys
  • 6,000 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.
