Dual-Functional Rhizobium dioscoreae Q9a for Glyphosate Biodegradation and Plant Growth Promotion: Insights into the Degradation Kinetics, Catabolic Pathways, Beneficial Properties, and Underlying Enzymatic Mechanisms.

PubMed · 2026-06-01

Scientists discovered a soil bacterium that breaks down glyphosate (the active ingredient in Roundup) while also helping plants grow — offering a potential two-in-one solution for cleaning up herbicide-contaminated farm soils and boosting crop health.

Strain Q9a degraded 50 mg/L of glyphosate within 9 days in liquid culture

The bacterium produced 45 μg/mL of the plant growth hormone indole-3-acetic acid and solubilized up to 150 mg/L of insoluble phosphate

Molecular analysis identified Serine-38 (Ser38) as the critical active site on enzyme GoxD responsible for breaking down glyphosate
