Scholarcy highlights

  • Chromium is a highly toxic nonessential metal found in different environmental settings
  • Plant-growth-promoting rhizobacteria alleviate the metal toxicity by adopting different strategies like biosorption and bioaccumulation, bioreduction to a less-toxic state, and chromate efflux. Some of these methods have been proposed as effective biological tools for removing chromium from contaminated locations
  • The detoxification of chromium by plant-growth-promoting rhizobacteria is likely to reduce the adversity of chromium to various agroecosystems and may serve as a good candidate for bacterial-based bioremediation of chromium-polluted soils
  • Megharaj M, Avudainayagam S, Naidu R Toxicity of hexavalent chromium and its reduction by bacteria isolated from soil contaminated with tannery waste
  • Zhu W, Chai L, Ma Z, Wang Y, Xiao H, Zhao K Anaerobic reduction of hexavalent chromium by bacterial cells of Achromobacter sp
