The dissolution of elemental selenium [Se(0)] during chemical weathering is an important step in the global selenium cycle. While microorganisms have been shown to play a key role in selenium dissolution in soils, the mechanisms of microbial selenium solubilization are poorly understood. In this study, we isolated a Bacillus species, designated as strain JG17, that exhibited the ability to dissolve Se(0) under oxic conditions and neutral pH. Growth of JG17 in a defined medium resulted in the… 

Extracellular sulfite is protective against reactive oxygen species and antibiotic stress in Shewanella oneidensis MR-1.

The results showed that sulfite is the major extracellular sulfur metabolite released to the growth medium under both aerobic and anaerobic growth conditions, and exogenous sulfite at physiological concentrations protected S. oneidensis MR-1 from hydrogen peroxide toxicity and enhanced tolerance to the beta-lactam antibiotics.

Developments in the study and applications of bacterial transformations of selenium species

The focus of this review is to present the state-of-the-art of all aspects of the investigations into the bacterial transformations of selenium species, and to consider the characterization and biotechnological uses of these transformations and their products.



Microbial oxidation of elemental selenium in soil slurries and bacterial cultures

The microbial oxidation of elemental selenium [Se(0)] was studied by employing 75Se(0) as a tracer. Live, oxic soil slurries demonstrated a linear production of mostly Se(IV), with the formation of

Selenium (IV,VI) reduction and tolerance by fungi in an oxic environment

The results demonstrate that activity of common soil fungi can influence Se form and distribution, and these organisms may therefore play a role in detoxifying Se-polluted environments.

Microbial oxidation and solubilization of precipitated elemental selenium in soil

Oxidation of elemental selenium (Se{sup 0}) leads to increased solubilization and enhanced bioavailability. In this work, laboratory microcosm experiments were conducted to study oxidation of Se{sup

Ecology and Biotechnology of Selenium-Respiring Bacteria

This review focuses on microorganisms that use selenate and selenite as terminal electron acceptors, in parallel to the well-studied sulfate-reducing bacteria, and overviews the significant advancements made in recent years on the role of SeRB in the biological selenium cycle.

Structural and Spectral Features of Selenium Nanospheres Produced by Se-Respiring Bacteria

Large differences in the optical properties (UV-visible absorption and Raman spectra) of purified extracellular nanospheres produced in this manner by the three different bacterial species differed substantially from those of amorphous Se(0) formed by chemical oxidation of H2Se and of black, vitreous Se(*) formed chemically by reduction of selenite with ascorbate.

Sulfur chemistry in bacterial leaching of pyrite

The data indicate that thiosulfate, trithionate, tetrathionates, and disulfane-monosulfonic acid are key intermediate sulfur compounds in oxidative pyrite degradation, and a novel (cyclic) leaching mechanism is proposed which basically is indirect.

Selenate Reduction to Elemental Selenium by Anaerobic Bacteria in Sediments and Culture: Biogeochemical Significance of a Novel, Sulfate-Independent Respiration

Results indicate that dissimilatory selenate reduction to elemental selenium is the major sink for selenia oxyanions in anoxic sediments and suggest application as a treatment process for removing selenio-oxyanions from wastewaters and also offer an explanation for the presence of selenite in oxic waters.

Arsenic and selenium in microbial metabolism.

This review highlights recent advances in ecology, biochemistry, and molecular biology and provides a prelude to the impact of genomics studies.

Selenium environmental cycling and bioavailability: a structural chemist point of view

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 relationships between selenium
