General Information

General Information	Comment	Organism
physiological function	both wild-type and strains lacking PitB are able to internalize tellurite into the cytoplasm and reduce the oxyanion to black nano-sized and rod-shaped tellurium particles. The strain lacking PitB shows an increased resistance to the tellurite toxic effects. At 0.1 mM tellurite, the biomass formation of the wild-type strain decreases by half, and the mutant strain shows greater ability to reduce tellurite with respect to the wild-type, which is related to the greater biomass production of the mutant	Pseudomonas putida
