********************************************************************** RIKEN BioResource Research Center - Japan Collection of Microorganisms JCM Mail News (2025.07.08) ********************************************************************** RIKEN BioResource Research Center - Japan Collection of Microorganisms (JCM) is pleased to update you with the latest information. ======= Contents ===================================================== - Special topic: Prokaryotic strains contributing proposals of new phyla and kingdoms - Isolation source category added in the Lists of JCM strains - Official BRC Bluesky (Social Media) Account Now Open - Newly cataloged strains (2025.03.01 - 2025.06.30) ====================================================================== +--------------------------------------------------------------------- Special topic: Prokaryotic strains contributing proposals of new phyla and kingdoms +--------------------------------------------------------------------- Currently, the International Code of Nomenclature of Prokaryotes (ICNP) covers the high-level taxonomic ranks "phylum", "kingdom" and "domain." There are two domains – Bacteria and Archaea – with four kingdoms formally approved within each domain. One of the four archaeal kingdoms is Nanobdellati. Our research group previously reported Nanobdella aerobiophila T (=JCM 33616T), which is the origin of this kingdom name. In 2024, another archaeal kingdom Promethearchaeati was validated based on Promethearchaeum syntrophicum MK-D1T (=JCM 39240T). Meanwhile, in the domain Bacteria, proposals for new phyla have been recently made one after another, such as the phylum Minisyncoccota, formerly referred to as the CPR (Candidate Phyla Radiation) clade, and the phylum Fidelibacterota, previously known as the 'Marine Group A' or SAR406 group. Both phylum names are derived from the genus names of Minisyncoccus archaeiphilus PMX.108T (=JCM 39522T) and Fidelibacter multiformis IA91T (=JCM 39387T), respectively. All the above species show special characteristics that could only be demonstrated through cultivation, such as obligate symbiosis with attachment to the cell surface of a specific host, formation of protrusions, or inability to grow without utilizing specific cellular components of other organisms. These reports have provided important insights not only for taxonomy but for whole microbiology, including physiology, ecology, and evolution. At present, strains MK-D1T and PMX.108T are only available from JCM among numerous international culture collections. JCM provides phylogenetically and physiologically diverse strains, in addition to the above strains, as live cultures to the scientific community. References: Kato et al. 2022.
