Soils, aquatic sediments, waste streams, and bodies of water are frequently contaminated with inorganic pollutants such as for example toxic metalloids, e.g. tellurite and selenite. Here we present our recent results on the role of dithiol: disulfide oxidoreductases (Dsb proteins) in mediating the exchange of reducing equivalents between tellurite and the membrane redox complexes in cells of the facultative phototroph Rhodobacter capsulatus. The role of facultative phototrophic bacteria as tellurite and selenite scavengers in aquatic enviromements will be discussed.

Abstract
Soils, aquatic sediments, waste streams, and bodies of water are frequently contaminated with inorganic pollutants such as for example toxic metalloids, e.g. tellurite and selenite. Here we present our recent results on the role of dithiol: disulfide oxidoreductases (Dsb proteins) in mediating the exchange of reducing equivalents between tellurite and the membrane redox complexes in cells of the facultative phototroph Rhodobacter capsulatus. The role of facultative phototrophic bacteria as tellurite and selenite scavengers in aquatic enviromements will be discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
