DELGADO-SARMIENTO, Pavel et al. Bioremediation of chromium VI by applying rhodopseudomonas palustris in industrial effluents coming from tannery. Rev. Bol. Quim [online]. 2020, vol.37, n.1, pp. 21-27. ISSN 0250-5460.

Abstract The effects of chemical substances when considered as pollutants are of major interest since they are translated as alterations of the functionality of organs or systems in living beings, organisms are very sensitive to the presence of exogenous elements coming from environmental pollution. In this Ínvestigation we boarded the study of the removal of chromium VI by means of the bacterium Rhodopseudomonas palustris when applied to contaminated waters. Chromium treatments (5 mg/L and 3 mg/L) were applied into bacterial solutions (400 mL and 300 mL) for times of 19 and 23 days periods in bioreactors. The elimination of chromium VI by bacteria was evaluated. On the basis of the results obtained we concluded that the level of concentration of chromium VI was reduced to below the máximum permissible limits of 0.5 mg/L. This research showed that inocula with tolerant bacteria can be used efficiently for the removal of chromium with characteristic concentrations of industrial and rnining effluents.
