Probiotics Database (PBDB)

The Probiotics Database (PBDB) is a comprehensive bioinformatics resource that systematically collects and categorizes probiotic strains derived from diverse fermented food sources. Currently housing 1,730 well-characterized probiotic strains, the database features a structured classification system including production-related (768 strains), research-oriented (264 strains), environmental protection (22 strains), disease prevention and treatment (17 strains), and other specialized categories (659 strains). Designed as a dynamic knowledge platform, PBDB provides essential biological information to support research across human health, animal science, and agricultural applications, with regular updates to incorporate new discoveries. Beyond serving as a reference repository, the database enables advanced bioinformatics analyses to elucidate probiotic mechanisms and facilitates the computational prediction of novel probiotic candidates from unexplored microbial resources. By integrating empirical data with analytical tools, PBDB significantly enhances our capacity to understand, develop, and apply probiotic solutions across multiple scientific and industrial domains.
