0This article introduces MetaSBT, a bioinformatics framework designed to index and classify massive collections of microbial genomes, including unidentified viruses often referred to as microbial dark matter. By utilizing Sequence Bloom Trees, the software provides a scalable and memory-efficient alternative to traditional alignment-based methods for organizing genetic data across all taxonomic levels. The researchers demonstrated the tool’s effectiveness by creating a database of over 190,000 viral genomes, uncovering thousands of previously unknown species and improving the detection of microbes in human gut samples. The framework is open-source and fully integrated into the Galaxy platform, facilitating accessible and reproducible metagenomic research. Ultimately, MetaSBT serves as a robust system for dynamically updating global microbial catalogs as new genomic data is discovered.
