Unlocking microbial dark matter: A biotechnology framework for replenishing the antibiotic pipeline.

A practical framework leverages integrated workflows to unlock microbial dark matter, revealing over 1,000 new antibiotic leads from uncultured bacteria.

• Why it matters: The antibiotic pipeline faces a crisis due to limited discovery of new scaffolds, as most microbial chemistry remains hidden in uncultured organisms and silent gene clusters, risking future drug shortages.
• What they did: The authors review challenges such as silent biosynthetic clusters, limited ecological sampling, and weak genome-metabolome links, and evaluate recent case studies employing multi-platform strategies to overcome these barriers.
• The result: This approach enables the transformation of microbial dark matter into accessible, mechanistically understood antibiotic candidates, expanding the pipeline and addressing urgent antimicrobial resistance needs.
