Expression Levels of hgcAB Genes and Mercury Availability Jointly Explain Methylmercury Formation in Stratified Brackish Waters

Eric Capo et al.

Summary: This study investigated the relationship between hgc genes and MeHg in the redox-stratified water columns of the Baltic Sea. The findings showed that hgc transcript abundance and the concentration of dissolved Hg-II-sulfide species were strong predictors of Hg-II methylation rate and MeHg concentration. The study also highlighted the versatility of putative Hg-II methylators in the water column of the Baltic Sea through genome reconstruction.

Trends in mercury concentrations and methylation in Minamata Bay, Japan, between

Akito Matsuyama et al.

Summary: The study found high levels of methylmercury in Minamata Bay seawater, suggesting methylation may occur year-round. Environmental factors like seawater temperature, salinity, and dissolved organic carbon influenced methylation, with bacterial community structure playing a key role. Methylmercury concentrations in suspended particulate matter were highest closer to the surface and decreased with depth, showing no correlation with dissolved methylmercury concentrations.

Mercury methylation by metabolically versatile and cosmopolitan marine bacteria

Heyu Lin et al.

Summary: This study identified potential novel marine Hg-methylating microorganisms with greater oxygen tolerance and broader habitat range than previously recognized, by conducting large-scale multi-omic analyses in a natural ecosystem and analyzing gene expression profiles along defined redox gradients. The findings highlighted the presence of putative microbial Hg methylators, such as Calditrichaeota, SAR324, and Marinimicrobia, with the latter showing the highest activity levels based on hgc transcription. Computational modeling predicted the functionality of HgcAB proteins from Marinimicrobia in Hg methylation, suggesting a key role in marine Hg methylation for this microbial group. Additionally, the study also associated several putative novel Hg methylators with terminal oxidases from aerobic respiratory chains.
