Bacterial and fungal diversity in the lorandite (TlAsS2) mine "Allchar" in the Republic of North Macedonia.
This study is the first to identify specific As- and Tl-tolerant fungal and bacterial and bacterial genera from Allchar mine, suggesting bioremediation and industrial potential.
Remedial Approaches against Arsenic Pollution
The study is devoted to a very urgent and acute problem for Georgia – remediation/restoration of the arsenic (As) mining and storage sites. The approach of a given work is based on using capabilities
Recent Advances in Arsenic Research: Significance of Differential Susceptibility and Sustainable Strategies for Mitigation
This comprehensive review of arsenic research has identified major population-based studies of the last 20 years indicating possible causes of differential susceptibility emphasizing arsenic methylation capacity, variation in host genome, and individual epigenetic pattern.


Comment on “A Bacterium That Can Grow by Using Arsenic Instead of Phosphorus”
Although their data show that GFAJ-1 is an extraordinary extremophile, consideration of arsenate redox chemistry undermines the suggestion that arsenate can replace the physiologic functions of phosphate.
A Bacterium That Can Grow by Using Arsenic Instead of Phosphorus
A bacterium is described, isolated from Mono Lake, California, that is able to substitute arsenic for phosphorus to sustain its growth and exchange of one of the major bio-elements may have profound evolutionary and geochemical importance.
GFAJ-1 Is an Arsenate-Resistant, Phosphate-Dependent Organism
It is shown that GFAJ-1 is able to grow at low phosphate concentrations, even in the presence of high concentrations of arsenate, but lacks the ability to grow in phosphorus-depleted medium, while efficiently scavenging phosphate.
