Indigenous microorganisms as potential bioremediators for environments contaminated with heavy metals

Heavy metal pollution is one the most serious environmental problems facing our planet today, and immediate solutions are needed. Heavy metals such as copper and chromium play an important role as trace elements in biochemical reactions, but these metals are toxic at higher concentrations

Scholarcy highlights

  • Heavy metal pollution is one the most serious environmental problems facing our planet today, and immediate solutions are needed. Heavy metals such as copper and chromium play an important role as trace elements in biochemical reactions, but these metals are toxic at higher concentrations
  • A chromium compound is used as a tanning agent, which has resulted in severe contamination near tanneries, with a mix of Cr(III) and Cr(VI)
  • This review discusses the toxic effects of Cu and Cr on the environment and on human health, as well as possible approaches for bioremediation of these metals using native microbes from our region
  • ► Approaches for Cu and Cr bioremediation by using native microbes are discussed
