BCCM/ULC : genomic research on Polar cyanobacteria
The BCCM/ULC public collection of cyanobacteria aims to gather a representative portion of Polar cyanobacterial diversity from different ecological origins (microbial mats, soil crusts, cryoconites, endoliths, etc.) and ensure their ex-situ conservation in a context of global change. These strains a...
