Nanosynbacteria Official Name for Ca. Saccharimonadia

Congrats to everyone on the monumental task of formally naming the first Minisyncoccota/Ca. Patescibacteria/Candidate Phyla Radtion Member we isolated in 2015— Nanosynbacter lyticus strain TM7x (type strain) with a publication in the IJSEM. 

Hendrickson, E. L., B. Bor, X. He, and J. S. McLean. "Nanosynbacter Lyticus Gen. Nov., Sp. Nov., an Ultrasmall, Obligate Epibiont Bacterium and the Proposal of Nanosynbacteraceae Fam. Nov., Nanosynbacterales Ord. Nov. And Nanosynbacteria Class Nov." Int J Syst Evol Microbiol 76, no. 5 (May 2026). https://doi.org/10.1099/ijsem.0.007162. https://www.ncbi.nlm.nih.gov/pubmed/42101953.

*** Class Ca. Saccharimonadia  is now Class Nanosynbacteria  so we can refer to all Ca. Saccharibacteria as Nanosynbacteria 

At some point in time all these names will be propagated through databases and should (fingers crossed) not ever change again since we have this formal publication which establishes the name.  

Note also Ca. Patescibacteria  (informally the Candidate Phyla Radiation) is now officially replaced by the name Minisyncoccota due to a recent paper that came out just before this publication. 

Please share widely and spread the word!
