Mapping the Microbial Communities Beneath Our Feet and Inside Our Guts

Why It Matters

By delivering comprehensive, searchable reference datasets, MGnify accelerates microbiome research that underpins disease treatment, sustainable agriculture, and bio‑based product development, giving scientists a faster path from raw sequencing to actionable insights.

Key Takeaways

• MGnify hosts 18 biome catalogues, 500k+ genomes.
• Human gut catalogue contains ~300,000 genomes.
• Over 12,000 researchers accessed MGnify genomes last year.
• Catalogues aid antimicrobial resistance, crop improvement, marine biotech.
• Continuous updates integrate new metagenome-assembled genomes.

Pulse Analysis

Metagenomics has transformed the study of microbial ecosystems by allowing scientists to sequence DNA directly from soil, water, or host tissues, bypassing the need to culture each organism in the lab. This approach generates massive datasets that require robust infrastructure for assembly, quality control, and annotation. EMBL‑EBI’s MGnify platform answers that need with one of the world’s largest microbiome analysis resources, offering automated pipelines that turn raw reads into high‑quality metagenome‑assembled genomes (MAGs) and curated isolate sequences. The result is a searchable repository that maps microbial diversity at unprecedented depth.

The MGnify biome catalogues now span 18 environments, from the human gut—home to almost 300,000 genomes—to agricultural rhizospheres, marine sediments, and even honeybee intestines. Each catalogue provides species‑level clusters, pangenomes, and functional annotations that highlight genes linked to antimicrobial resistance, nutrient cycling, or novel biosynthetic pathways. Researchers can compare their own samples against these references to identify taxa, assess gene abundance, or discover previously uncharacterized microbes. Such capabilities have already supported projects in crop trait optimization, livestock health, and the development of sustainable marine bioproducts.

Because MGnify continuously incorporates newly deposited sequencing data, the catalogues evolve alongside the expanding global metagenomics effort. This dynamic updating ensures that emerging pathogens, climate‑adapted strains, or industrially relevant enzymes are rapidly reflected in the reference set. For biotech firms and pharmaceutical pipelines, the platform shortens the time from discovery to application, reducing reliance on costly culturing and de‑novo genome assembly. As open‑access data sharing becomes the norm, MGnify’s comprehensive, annotated microbial maps will be a cornerstone for precision medicine, climate‑smart agriculture, and the next generation of bio‑based economies.
