Mathematical modeling on bacterial isolates for dierent concentrations of hexavelant chromium

Abstract:

Microorganisms are the most abundant and diverse living beings on theВ planet, within this group, are the bacteria. There are several factors controllingВ abundance and bacterial growth such that the decient or excessive concentrationВ of certain elements such as heavy metals (HM), the most essential forВ bacterial growth. However, high concentrations of these metals can be highlyВ toxic. One of the HM with the greatest impact on the environment is Chromium, В which is commonly found in the form of chromates, dichromate, oxides and sulfates; In this sense, hexavalent chromium (Cr (VI)) is a highly toxic agent, which can be reduced by the environment to less toxic forms (Cr (III)), but when the metal levels exceed the capacity of reduction can become a pollutant, directly affecting the abundance and normal growth of bacteria associated with environments contaminated with this metal. The eect of dierent …
