Abstract:The year 2023 marks the centenary of the publication of the Bergey's Manual of Determinative Bacteriology. Bergey's Manual of Determinative Bacteriology was created to establish clear criteria for the classification of prokaryotic microorganisms and to initiate a mission to explore the taxonomy of prokaryotic microorganisms. With the innovation and promotion of biology, physics, chemistry, molecular biology, bioinformatics and related research techniques, and the interdisciplinary nature of microbial taxonomy, which is based on phylogenetic relationships and polyphasic taxonomy, the study of the evolution and biology of microbial species and interspecies correlation has led to a rapid increase in the number of newly discovered microbial species and information on their biological characteristics. The Bergey's Manual of Determinative Bacteriology was renamed to Bergey's Manual of Systematics of Archaea and Bacteria in 2015 and made available electronically, allowing for quick updates and a new dynamic in the field of systematic taxonomy of prokaryotic microorganisms. The "Bergey's International Society for Microbial Systematics (BISMiS)" was established in 2009 to enhance the dissemination of systematic microbiological biotechnology and to promote international academic exchange in the field of microbiology. This review provides a comprehensive overview of the history and recent developments of the Bergey's Manual of Determinative Bacteriology and "Bergey's International Society for Microbial Systematics (BISMiS)", as well as an outlook on their future directions.
