ADVANCES IN PLANT-MICROBE MEDIATED REMEDIATION OF GLYPHOSATE

Abstract

Glyphosate (GLA) has long been the primary herbicide used to control both annual and perennial weeds. However, its extensive application has resulted in widespread persistence in agroecosystems, posing risks to both biotic and abiotic components of the environment. To address these impacts, various remediation strategies—such as adsorption, photocatalytic degradation, and microbial degradation—have been investigated. Among these, microbial degradation, particularly rhizodegradation, stands out for its efficiency, versatility, and eco-friendly nature. Rhizodegradation relies on diverse microorganisms that metabolize GLA, using its carbon, nitrogen, and phosphorus as nutrient sources.

This review consolidates current understanding of microbial GLA degradation, emphasizing the role of GLA-degrading microorganisms in remediating contaminated environments. It explores the mechanisms by which microbes break down GLA and the interactions that facilitate its detoxification. Additionally, the review assesses the practicality and effectiveness of employing GLA-degrading microbes in bioremediation across various ecological contexts. By detailing microbial degradation pathways and their environmental significance, this article provides a solid foundation for developing sustainable strategies to manage GLA contamination and mitigate its ecological consequences.
