The heterocytous cyanobacterium Trichormus sp. PCC 7120 is a model cyanobacterium used to unravel the cellular differentiation, physiological studies and mutational insertions to examine heterocyst patterns.
The PCC strains and genomes
Cyanobacteria are oxygenic photosynthetic prokaryotes that contribute largely to the balance between CO2 and O2 in the atmosphere. Adapted to a wide range of environmental conditions, they colonize most ecosystems. In continental and marine water bodies, the abundance of bloom-forming representatives disrupts the equilibrium of these environments and the potentially associated cyanotoxins may be harmful to animals and Man.
Since July 2009, the Collection of Cyanobacteria houses the Pasteur Cultures of Cyanobacteria collection and continues its different service activities (acquisition, preservation and distribution of the organisms). This biological resource is also used for our own research programs focused on the Evolution of cyanobacteria and the genetics of the natural products of these microorganisms.
