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

Selenium species, particularly the oxyanions selenite (SeO3 2−) and selenate (SeO4 2−),
are significant pollutants in the environment that leach from rocks and are released by …

Selenium (Se) is not only a strategic element in high-tech electronics and an essential trace
element in living organisms, but also a potential toxin with low threshold concentrations …

Microbes play important roles in the transport and transformation of selenium (Se) in the
environment, thereby influencing plant resistance to Se and Se accumulation in plant. The …

Selenium concentrations in the soil environment are directly linked to its transfer in the food
chain, eventually causing either deficiency or toxicity associated with several physiological …

The bioavailability of selenium (Se) was determined in bacterial strains that reduce selenite
to red elemental Se (Se o). A laboratory strain of Bacillus subtilis and a bacterial rod isolated …

Selenium is an essential micronutrient required for natural biological systems such as anti-
oxidative systems. Despite such beneficial aspect, contamination of selenium and its …

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 …

Selenium (Se) is an essential element for most organisms yet can cause severe negative
biological consequences at elevated levels. The oxidized forms of Se, selenate [Se (VI)] and …

The fate of selenium in the environment is controlled, in part, by microbial selenium
oxyanion reduction and Se (0) precipitation. In this study, we identified a genetic regulator …
