Biogeochemistry: Mercury methylation on ice

Metagenomic analysis of Antarctic sea-ice and brine reveals the presence of hgcAB-like genes in the microaerophilic marine bacterium Nitrospina. These are similar to ones responsible for mercury methylation in anaerobic microorganisms and provide a plausible mechanism for mercury methylation in oxic marine environments.
