As reported in Nature Biotechnology, the known diversity of bacteria and archaea has been expanded by 44% through a publicly available collection of more than 52,000 microbial genomes from environmental samples, resulting from a JGI-led collaboration involving more than 200 scientists (the IMG Data Consortium) around the world. Enabled by the repositories of data and computational tools established and maintained by JGI, KBase, and NERSC, with the contributions of a growing research community.
