Microbial-assistance and chelation-support techniques promoting phytoremediation under abiotic stresses

Area of Science:

• Environmental Science
• Biotechnology

Background:

• Phytoremediation uses plants to remove heavy metals (HMs) from polluted sites.
• Abiotic stresses (drought, salinity, heat) and HMs toxicity reduce phytoremediation efficiency by limiting plant growth and metal uptake.

Purpose of the Study:

• To explore microbial-assisted and chelation-supported approaches for enhancing phytoremediation under abiotic stress.
• To investigate how these strategies mitigate heavy metal toxicity and improve plant resilience.

Main Methods:

• Microbial assistance utilizes microbes, like fungi producing siderophores, to increase metal solubility and plant bioavailability.
• Chelation support employs organic acids and amino acids to enhance soil metal absorption, reduce HM toxicity, and improve plant stress tolerance.

Main Results:

• Microbial and chelation strategies promote plant growth and increase heavy metal uptake.
• These approaches effectively alleviate the toxic effects of heavy metals and abiotic stresses.

Conclusions:

• Managed microbial-assisted and chelation-supported methods offer a more efficient and sustainable approach to phytoremediation.
• These strategies significantly advance phytoremediation technology, expanding its application to challenging environmental conditions.
