Story summary

Researchers at Rockefeller University created a method to extract large DNA fragments from soil, allowing access to uncultured bacteria.
This method uncovered hundreds of new bacterial genomes and two antibiotics, erutacidin and trigintamicin.
Erutacidin disrupts bacterial membranes, while trigintamicin targets a protein-unfolding motor, both effective against drug-resistant bacteria.
The study emphasizes the potential of "microbial dark matter" for discovering bioactive molecules.
This breakthrough may transform microbiology and drug discovery by revealing hidden microbial ecosystems.
