AlgaeBase is a database of information on algae that includes terrestrial, marine and freshwater organisms. At present, the data for the marine algae, particularly seaweeds, are the most complete

Algobank-Caen is the microalgal culture collection of the University of Caen Basse-Normandie, France. Algobank-Caen provides monospecific microalgal strains for research, education and industry. Simple or multi-criteria searches can be conducted in the catalogue of strains. The collection consists of 471 strains of marine, brackish water and freshwater microalgae.

This unique bank of Australian biodiversity contains marine and freshwater microalgal classes sourced from tropical Australia to Antarctica.

 As Canada's national service collection of freshwater algae and cyanobacteria the collection maintains around 500 strains of algae and cyanobacteria

The CCAC maintains more than 2700 strains from around the world. The strains are clonal or single cell isolates, if not otherwise stated. Approximately 50% of the strains are currently available to the public.

The Collection functions as the national service collection of algae and protozoa in the UK.

Culture Collections Information Worldwide is a database management system for culture collections in the world

The University of Manchester has compiled a microalgae strain catalogue that includes strain cultivation, composition and characteristics of a wide variety of microalgae strains.

Culture strains of cyanobacteria, eukaryotic microalgae, protozoa and endangered algae available for educational, research and developmental purposes

The NCMA maintains the largest and most diverse collection of publically available marine algal strains in the world

The RCC maintains 3,478 strains of marine phytoplankton, bacteria and viruses.

CCCM maintains living specimens of marine phytoplankton, freshwater microalgae and fungal isolates for research, teaching and commercial use

The CAUP Culture Collection represents rather a small algal collection. Never-the-less, it holds many taxonomically important strains, e.g. authentic cultures of newly described species.

The SAG Culture Collection of Algae primarily comprises microscopic algae and cyanobacteria from freshwater or terrestrial habitats, but also marine algae are available. With presently over 2400 strains (representing 538 genera and 1424 species) the SAG is among the three largest culture collections of algae in the world. 

FACHB is the main algal culture collection in China. The collection currently holds more than 2000 strains, belonging to over 120 genera, eight phyla. It preserves numerous freshwater species as well as a small number of marine and brackish species.

NIVA-CCA consists of over 900 strains of prokaryotic and eukaryotic photosynthetic microalgae. Several strains are unique to the collection.

The main Plymouth Collection consists of some 400 strains from 80 genera of marine phytoplankton

The Scandinavian Culture Collection of Algae and Protozoa at the University of Copenhagen comprises more than 1000 strains (c. 285 genera and 531 species) with representatives from most algal divisions. 865 strains are available to the public.

The Spanish Bank of Algae (BEA-Banco Español de Algas) is a service of the Scientific and Technological Park Foundation of the University of Las Palmas de Gran Canaria (ULPGC).
BEA holds strains from tropical and subtropical areas, in particular of the MACARONESIAN Region. These cultures have strain numbers preceded by BEA.

UTEX,  The Culture Collection of Algae at the University of Texas at Austin includes approximately 3,000 different strains of living algae, representing most major algal taxa.  Cultures in the Collection are used for research, teaching, biotechnology development, and various other projects throughout the world. This website contains a listing of the cultures maintained by UTEX, conditions for their maintenance.
