Methylmercury (MeHg) is an organic form of the global pollutant mercury (Hg) which readily accumulates in fish tissue.A majority of Hg methylation is a result of microbial activity and the abundance of inorganic Hg within the water reservoirs (Eckley et al.,2017).Compared to natural lakes and rivers,reservoirs have elevated Hg levels from the decomposition of recently flooded organic material which promote Hg release and enhance microbial methylation of Hg (Eckley et al.,2017).Microorganisms containing the gene clusters hgcA and hgcB,such as sulfate reducing bacteria (SRB) and iron reducing bacteria (FeRB),have been demonstrated to be contributors to MeHg (Duet al.,2017;Eckley et al.,2017;Xiang et al.,2018).
