Abstract
Jiang et al. present the Extreme Environment Microbiome Catalog (EEMC), comprising 78,213 bacterial and archaeal genomes, as a global resource for microbial diversity and antimicrobial discovery. Its scale and experimental peptide characterization are substantial contributions. However, a global framing requires evidence that regional data were systematically sought, rather than simply aggregated. A targeted accession audit identifies public datasets whose project identifiers are absent from the published EEMC project list, including datasets from Latin America, Africa and the Global North. These findings identify regional evidence requiring reconciliation with catalog holdings and eligibility criteria; they do not establish whether exclusion rates differ between regions.
