Number of subspecies cited in this file: 0

Classification (Warning: see also the file "Classification of prokaryotes: Introduction").

 

Preliminary remark

In June 1985 the Subcommittee on the taxonomic of Phototrophic Bacteria proposed that names of cyanobacteria described and validly published as blue-green algae under the International Code of Botanical Nomenclature are recognized as having been published under the Bacteriological Code (1990 Revision) [1].

In September 1986, the Judicial Commission agreed unanimously to recommend the following to the ICSB (now ICSP): those names of taxa of Cyanobacteria and Cyanophyta that are valid under the Botanical Code be considered valid under the Bacteriological Code for the purpose of preparing an acceptance list comparable to the Approved Lists of Bacterial Names [2]. However, "Declarations of intent" by the Judicial Commission were not taken up by the ICSB (now ICSP).
In 2003, the "Subcommitteee on the taxonomy of phototrophic bacteria" [3] proposed the preparation of a list of approved names of cyanobateria under the Bacteriological Code and a small committee was appointed to prepare such a list. However, such a list is not yet available.

Consequently, names of cyanobacteria described and validly published as blue-green algae under the International Code of Botanical Nomenclature have no standing in bacterial nomenclature, unless they are again described under the Rules of the Bacteriological Code (1990 revision).
