Cyanobacterium is a genus of cyanobacteria. Unusual for cyanobacteria, it is published under the International Code of Nomenclature of Prokaryotes (with a living-culture type specimen). It became a validly published name in 2022. [2]
It contains one validly-published species, the type species Cyanobacterium stanieri. [2] There is an effectively (but not validly) published "Cyanobacterium aponinum" Moro et al. 2007. [3]
GTDB splits Cyanobacterium stanieri into two species-sized clusters and reports three more unnamed species clusters in its understanding of Cyanobacterium. The "Cyanobacterium aponinum PCC 10605" RefSeq genome GCF_000317675.1 is assigned to different genus with a placeholder name, PCC-10605, under GTDB's version of Cyanobacteriaceae. [4] GTDB's version of the Cyanobacteriaceae also includes Geminocystis and two more placeholder genera. [5]
