Rhizobacteria and Plant Symbiosis in Heavy Metal Uptake and Its Implications for Soil Bioremediation
Certain species of plants can benefit from synergistic effects with plant growth-promoting rhizobacteria (PGPR) that improve plant growth and metal accumulation, mitigating toxic effects on plants and increasing their ...
Understanding selenium biogeochemistry in engineered ecosystems: Transformation and analytical methods
Selenium is used extensively in many industries, and it is necessary for human nutrition. On the other hand, it is also toxic at slightly elevated concentrations. With the advent of industrialisation, selenium concentrations ...
An artificial metalloenzyme for carbene transfer based on a biotinylated dirhodium anchored within streptavidin
We report on artificial metalloenzymes that incorporate a biotinylated dirhodium core embedded within engineered streptavidin (Sav hereafter) variants. The resulting biohybrid catalyzes the carbene insertion in C–H bonds ...
Red mud as secondary source for critical raw materials – Purification of rare earth elements by liquid/liquid extraction
BACKGROUND Critical raw materials (CRM) are crucial to Europe's economy and essential to maintaining and improving our quality of life due to their usage for production of many devices. Red mud is generated from alumina ...
Re-using bauxite residues: benefits beyond (critical raw) material recovery
Since the world economy has been confronted with an increasing risk of supply shortages of critical raw materials (CRMs), there has been a major interest in identifying alternative secondary sources of CRMs. Bauxite residues ...
