Selenite and tellurite reduction by Shewanella oneidensis.
نویسندگان
چکیده
Shewanella oneidensis MR-1 reduces selenite and tellurite preferentially under anaerobic conditions. The Se(0) and Te(0) deposits are located extracellularly and intracellularly, respectively. This difference in localization and the distinct effect of some inhibitors and electron acceptors on these reduction processes are taken as evidence of two independent pathways.

Selenite reduction by Shewanella oneidensis MR-1 is mediated by fumarate reductase in periplasm
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 biological effects of selenium. However, the mechanism behind such a biological process remains unrevealed yet. Here we use Shewanella oneidensis MR-1, a widely-distributed dissimilatory metal-reducing bacterium ...
متن کاملInvestigating different mechanisms for biogenic selenite transformations: Geobacter sulfurreducens, Shewanella oneidensis and Veillonella atypica.
The metal-reducing bacteria Geobacter sulfurreducens, Shewanella oneidensis and Veillonella atypica, use different mechanisms to transform toxic, bioavailable sodium selenite to less toxic, non-mobile elemental selenium and then to selenide in anaerobic environments, offering the potential for in situ and ex situ bioremediation of contaminated soils, sediments, industrial effluents, and agricul...
متن کاملSe (IV) triggers faster Te (IV) reduction by soil isolates of heterotrophic aerobic bacteria: formation of extracellular SeTe nanospheres
BACKGROUND Selenium and Tellurium have many common chemical properties as both belong to group 16 of the periodic table. High toxicities of Se and Te oxyanions cause environmental problems in contaminated soils and waters. Three strains (C4, C6 and C7) of selenite reducing and nanoparticle forming aerobic bacteria which were isolated from agricultural soils of India containing high concentratio...
متن کاملDeciphering the electron transport pathway for graphene oxide reduction by Shewanella oneidensis MR-1.
We determined that graphene oxide reduction by Shewanella oneidensis MR-1 requires the Mtr respiratory pathway by analyzing a range of mutants lacking these proteins. Electron shuttling compounds increased the graphene oxide reduction rate 3- to 5-fold. These results may help facilitate the use of bacteria for large-scale graphene production.
متن کاملDraft Genome Sequence of a Selenite- and Tellurite-Reducing Marine Bacterium, Lysinibacillus sp. Strain ZYM-1
Lysinibacillus sp. ZYM-1, a Gram-positive strain isolated from marine sediments, reduces selenite and tellurite efficiently. Meanwhile, it also exhibits high resistance to Zn2+ and Mn2+. Here, we report the draft genome sequence of strain ZYM-1, which contains genes related to selenite and tellurite reduction and also metal resistance.
