A specific type of bacteria called Stenotrophomonas can quickly turn mercury into a gas and has genes that become more active when exposed to mercury.
Scientific Claim
Stenotrophomonas sp. MA5 demonstrates rapid mercury volatilization and resistance, with mer genes upregulated upon mercury exposure.
Source Excerpt
“In another study, Stenotrophomonas sp. MA5, also isolated from SRS, demonstrated rapid mercury volatilization and resistance. Whole genome sequencing revealed a transposon-derived merRTPADE operon, with qRT-PCR confirming ~40-fold upregulation of mer genes upon Hg2⁺ exposure. This strain depleted over 90% of spiked Hg2⁺ within 24 h, highlighting its bioremediation potential.”

A survey of bacterial and fungal community structure and functions in two long-term metalliferous soil habitats
The study isolated this specific strain and conducted genomic and functional analysis to confirm mercury resistance and volatilization capabilities.
