Methylmercury Resistance in Desulfovibrio desulfuricans Strains in Relation to Methylmercury Degradation [PDF]

Applied and Environmental Microbiology, 1993
Two strains of Desulfovibrio desulfuricans , one known to synthesize monomethylmercury from ionic mercury, were grown to determine methylmercury toxicity and for comparison with an anaerobic strain of Clostridium pasteurianum , a H 2 producer, and with the broad ...

Heavy Metal Contamination: Impacts From Plants to the Food Chain and Eco‐Friendly Amelioration Strategies

AgriFood: Journal of Agricultural Products for Food, EarlyView.
Heavy metal pollution reduces soil health and threatens food safety by entering plants; however, the use of nanoparticles, biofertilizers, and organic fertilizers such as biochar offers a promising strategy for improvement and sustainable agriculture. ABSTRACT Heavy metal (HM) pollution, resulting from human activities such as mining and the excessive ...

A Novel Role of MerC in Methylmercury Transport and Phytoremediation of Methylmercury Contamination

Biological & Pharmaceutical Bulletin, 2017
MerC, encoded by merC in the transposon Tn21 mer operon, is a heavy metal transporter with potential applications for phytoremediation of heavy metals such as mercuric ion and cadmium. In this study, we demonstrate that MerC also acts as a transporter for methylmercury.

Somatosensory Disturbance and Long‐Term Exposure to Methylmercury: A Comprehensive Review

Journal of Applied Toxicology, EarlyView.
ABSTRACT Chronic exposure to methylmercury remains a significant public health concern, particularly in populations with high fish consumption. Somatosensory disturbances are among the most frequently reported neurological manifestations, even at exposure levels below internationally established safety thresholds. This review aims to synthesize current
