Bioremediation

18.4K
Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

Extraction: Advanced Methods

447
Metal ions can be separated from one another by complexation with organic ligands–the chelating agent– to form uncharged chelates. Here, the chelating agent must contain hydrophobic groups and behave as a weak acid, losing a proton to bind with the metal. Since most organic ligands used in this process are insoluble or undergo oxidation in the aqueous phase, the chelating agent is initially added to the organic phase and extracted into the aqueous phase. The metal-ligand complex is...

Area of Science:

  • Environmental Microbiology
  • Bioremediation
  • Heavy Metal Contamination

Background:

  • Soil heavy metal contamination poses global risks to agriculture, environment, and human health.
  • Microbial strains from contaminated sites show tolerance to heavy metals like chromium (Cr), lead (Pb), and zinc (Zn).
  • Bacillus marisflavi and Trichoderma longibrachiatum demonstrate significant tolerance to these metals.

Purpose of the Study:

  • To evaluate the bioremediation potential of Bacillus marisflavi and Trichoderma longibrachiatum for Cr, Pb, and Zn.
  • To quantify the removal efficiency of these microbial strains for specific heavy metals.
  • To explore the application of these microbes in environmental cleanup strategies.

Main Methods:

  • Isolation and screening of microbial strains from industrially contaminated soil.
  • Bioremediation experiments to assess heavy metal removal.
  • Quantification of heavy metals using electrochemical screen-printed electrodes (SPE).
  • Morpho-structural analysis (SEM/EDX) and functional group identification (FTIR) to confirm metal uptake mechanisms.

Main Results:

  • Trichoderma longibrachiatum removed 87% of Cr and 67% of Zn.
  • Bacillus marisflavi removed 86% of Pb, outperforming T. longibrachiatum (48%).
  • SEM/EDX confirmed metal ion presence on microbial cell surfaces.
  • FTIR analysis indicated biosorption via hydroxyl, carboxyl, and amino groups.

Conclusions:

  • Trichoderma longibrachiatum is a promising candidate for Cr and Zn bioremediation.
  • Bacillus marisflavi shows potential for Pb bioremediation applications.
  • These microbial strains offer viable biological solutions for heavy metal pollution control.
