The Roscoff Culture Collection (RCC) maintains about 2450 and of viruses infecting phytoplankton. It focuses in particular on coccoid cyanobacteria (Prochlorococcus and Synechococcus), picoeucaryotes and coccolithophorids. Strains originate from a very wide range of oceanic regions from the tropics to the arctic, through temperate seas.
The Microbial Observatory of the Laboratoire Arago (MOLA) collection maintain 727 environmental bacterial strains in our collection, with new ones being added each week. Microorganisms are isolated from samples taken during oceanographic cruises all over the globe: from oligotrophic waters to the most eutrophic, at the water interface with air or sediments, or from the water column. They also isolate symbiotic bacteria associated with animals.
The Mediterranean Culture Collection of Villefranche (MCCV) is a new collection of marine microplanktonic organisms isolated mainly from Mediterranean Sea and especially from the Bay of Villefranche. Those protists can be auto-, mixo- or hetero-trophic organisms. Currently, MCCV is focused on dinoflagellates and diatoms. The Mediterranean Culture Collection of Villefranche also maintains some benthic unicellular auto- or mixo-trophic strains, such as the toxic genus Ostreopsis and the associated microalgae.
