New DNA techniques reveal unseen soil bacteria and antibiotic candidates

phys.org

New DNA techniques have uncovered hundreds of previously unknown bacterial genomes and two promising antibiotic candidates from soil. Researchers developed a method to extract large DNA sequences from soil, enabling genomic analysis of unculturable bacteria and the discovery of potential new drugs. This breakthrough offers a way to study the vast "microbial dark matter" and could lead to a new era of antibiotic discovery, addressing the growing threat of multidrug resistance.
