The on-line database of cyanobacterial genera Tomáš Hauer & Jiří Komárek

Dear users,
Due to time constraints we are no longer able to update our database. We are keeping it running as of early April 2023. We hope to resume continuous updates in the near future.


The CyanoDB 2.0 is highly modified version of CyanoDB. It reflects broad availability of literature and huge amount of molecular data available. The primary goal of CyanoDB 2.0 is to be a reference tool for taxonomists and other persons interested in taxonomy and diversity of Cyanobacteria and provide information on primary descriptions of taxa and reference molecular data provided descriptions and revisions.
Since we focus primary on cyanobacterial genera, not all species are included at this time, but we are working hard to include all valid species as well.

We use the taxonomy according to KOMÁREK J., KAŠTOVSKÝ J., MAREŠ J., JOHANSEN J.R. (2014): Taxonomic classification of cyanoprokaryotes (cyanobacterial genera) 2014, using a polyphasic approach. Preslia. 86: 295–335.
