New insights into efficient iron sulfide oxidation for arsenic immobilization by microaerophilic and acidophilic Fe(II)-oxidizing bacteria under micro-oxygen and acidic conditions Open
Microbial-mediated FeS oxidation to Fe(Ⅲ) minerals via chemolithoautotrophic Fe(Ⅱ) oxidizers under pH/O₂ limitations engages As immobilization. However, this process is constrained under the dual stress of micro-oxygen and acidic condition…

Herbarium and field studies of nickel hyperaccumulator plants from ultramafic soils in Guatemala Open
Until 2019, there were no published reports of trace element hyperaccumulation in the plants of Central America or Mexico. Recent reports, based mostly on measurement of herbarium specimens using x‐ray fluorescence (XRF) spectroscopy, have…

Thallium hyperaccumulation status of the violets of the Allchar arsenic–thallium deposit (North Macedonia) confirmed through synchrotron µXRF imaging Open
The abandoned Allchar Mine in the Republic of North Macedonia is a globally unique deposit with the highest known grades of thallium (Tl) and arsenic (As) mineralization. We aimed to determine the distribution of As and Tl in whole dehydra…

Hyperaccumulator plant discoveries in the Balkans: Accumulation, distribution, and practical applications Open
Hyperaccumulator plants are able to tolerate extremely high concentrations of metals/metalloids in the soil in which they grow and to accumulate high concentrations in their shoots. To date, a total of 31 hyperaccumulator plant species hav…

Intensive cycling of nickel in a New Caledonian forest dominated by hyperaccumulator trees Open
SUMMARY The hyperaccumulator Pycnandra acuminata is a New Caledonian rainforest tree known to have the highest concentration of nickel in any living organism, with 25 wt% nickel in its latex. All trees (with a diameter of >10 cm) and soil …

The potential of <i>Blepharidium guatemalense</i> for nickel agromining in Mexico and Central America Open
The aim of this study was to assess the potential of the woody nickel hyperaccumulator species Blepharidium guatemalense (Standl.) Standl. for agromining in southeastern Mexico. Pot trials consisting of nickel dosing (0, 20, 50, 100, and 2…

Population Genetics of Odontarrhena (Brassicaceae) from Albania: The Effects of Anthropic Habitat Disturbance, Soil, and Altitude on a Ni-Hyperaccumulator Plant Group from a Major Serpentine Hotspot Open
Albanian taxa and populations of the genus Odontarrhena are most promising candidates for research on metal tolerance and Ni-agromining, but their genetic structure remains unknown. We investigated phylogenetic relationships and genetic di…

Agromining for nickel: a complete chain that optimizes ecosystem services rendered by ultramafic landscapes Open
Serpentine (i.e. ultramafic) outcrops in Europe cover >10,000 km(2) and have a low fertility and low productivity, making them unattractive for traditional agriculture. Many of these areas are slowly abandoned by local farmers, with a rura…
