Green Solutions to a Growing Problem: Harnessing Plants for Antibiotic Removal from the Environment

Area of Science:

• Environmental Science
• Bioremediation
• Ecology

Background:

• Antibiotic pollution is a major global issue, leading to ecological disruption and the spread of antibiotic resistance genes (ARGs).
• Conventional methods for removing antibiotics from the environment are often inefficient or too expensive for broad application.
• Phytoremediation, utilizing plants and their associated microbes, presents a sustainable, cost-effective, and eco-friendly alternative.

Purpose of the Study:

• To synthesize the mechanisms of plant-antibiotic interactions in phytoremediation.
• To review high-performing plants and their efficacy in remediating various antibiotic classes.
• To explore the role of rhizosphere microbes and future strategies for enhancing phytoremediation.

Main Methods:

• Comprehensive literature review of physiological, biochemical, and ecological mechanisms.
• Analysis of plant-antibiotic interactions including phytoextraction, phytodegradation, rhizodegradation, and phytostabilization.
• Evaluation of aquatic and terrestrial plant species for antibiotic remediation capabilities.

Main Results:

• Plants interact with antibiotics through various mechanisms like phytoextraction and phytodegradation.
• Specific aquatic (e.g., Lemna minor, Eichhornia crassipes) and terrestrial (e.g., Brassica juncea, Zea mays) plants show promise for remediating major antibiotic classes.
• Rhizosphere microbes and engineered systems significantly enhance phytoremediation efficiency.

Conclusions:

• Phytoremediation is a viable strategy for reducing environmental antibiotic contamination and combating antimicrobial resistance.
• Challenges include variable efficiency, phytotoxicity, and incomplete understanding of degradation by-products.
• Future research should focus on genetic engineering, microbiome optimization, and advanced monitoring to improve scalability and performance.
