Our Cultures

CCAP currently maintains over 2500 strains of algae and protozoa

Haematococcus pluvialis; CCAP 1547/7; CCAP 1445/1; CCAP917/5; CCAP 291/1; CCAP 1060/10; CCAP 211/54; CCAP 1131/1; Pseudanabaena sp.; CCAP 1660/3B; CCAP 1398/2

  • a wide range of microalgal taxa, including the cyanobacteria
  • small thalloid red algae
  • a range of small multicellular seaweeds, including over 300 strains of Ectocarpus
  • free-living non-pathogenic protozoa
  • a small number of ACDP Class II, potentially pathogenic protozoa (all Acanthamoeba spp.)

Strains are primarily maintained by serial sub-culture although about 30% of the algal strains and 2% of the protozoan strains are cryopreserved. In order to maintain genetic stability most effectively, research is continuing to develop protocols to increase the number and diversity of cryopreserved strains throughout the Collection.


All cultures are freshly prepared to order, so when ordering please allow sufficient time for the cultures to be grown. For orders of one culture of each strain, 4 weeks is usually sufficient, but please allow extra time for multiple cultures of each strain, or for strains which are held at CCAP only under cryopreservation (as indicated in the strain data).


We hold strains specifically recommended for aquaculture use or ecotoxicology and biocide testing, and also supply a School's Kit in conjunction with the Society for General Microbiology.
