Archives of microbiology, 191(5), 473-476 (2009-03-31)
Potassium tellurite is highly toxic to most forms of life and specific bacterial tellurite defense mechanisms are not fully understood to date. Recent evidence suggests that tellurite would exert its toxic effects, at least in part, through the generation of

Potassium tellurite (K(2)TeO(3)) is harmful to most organisms and specific mechanisms explaining its toxicity are not well known to date. We previously reported that the lpdA gene product of the tellurite-resistant environmental isolate Aeromonas caviae ST is involved in the
Miguel E Castro et al.
Biochemical and biophysical research communications, 375(1), 91-94 (2008-08-05)
Potassium tellurite (K(2)TeO(3)) is extremely toxic for most forms of life and only a limited number of organisms are naturally resistant to the toxic effects of this compound. Crude extracts prepared from the environmental isolate Aeromonas caviae ST catalize the

A selective enrichment broth (SVV) was formulated to allow concurrent growth of Salmonella spp., V. parahaemolyticus, and V. cholerae. Potassium tellurite and sodium citrate were added as the inhibitors, while glucose, mannitol, anhydrous sodium sulfite and sodium pyruvate were employed
José M Pérez et al.
PloS one, 2(2), e211-e211 (2007-02-15)
Biochemical, genetic, enzymatic and molecular approaches were used to demonstrate, for the first time, that tellurite (TeO(3) (2-)) toxicity in E. coli involves superoxide formation. This radical is derived, at least in part, from enzymatic TeO(3) (2-) reduction. This conclusion
