In nature, selenium is actively cycled between oxic and anoxic habitats, and this cycle plays
an important role in carbon and nitrogen mineralization through bacterial anaerobic …

Selenium is an essential trace element for humans, animals and microorganisms. Microbial
transformations, in particular, selenium dissimilatory reduction and bioremediation …

Selenium is usually known as the 'double-edged sword element'for its dual toxic and
beneficial character to health. Since the pioneer works by Schwarz and Foltz on the …

In situ reduction of selenite to elemental selenium (Se (0)), by microorganisms in sediments
and soils is an important process and greatly affects the environmental distribution and the …

Denitrification is a facultative respiratory pathway in which nitrite (NO2−), nitric oxide (NO),
and nitrous oxide (N2O) are successively reduced to nitrogen gas (N2), effectively closing …

Endemic selenium (Se) deficiency is a major worldwide nutritional challenge. Organic Se
can be synthesized through physical and chemical methods that are conducive to human …

Selenium nanoparticles (SeNPs) can be produced by biogenic, physical, and chemical
processes. The physical and chemical processes have hazardous effects. However …

Biogenic formation of nano-sized particles composed of various materials (in particular,
