Biostimulation of wheat (Triticum aestivum L.) during copper stress by Pseudomonas spp. fluorescents

Abstract

The study focused on the bioremediation of copper-polluted soil using Pseudomonas fluorescents. Bioremediation, which involves the use of living organisms to reduce the concentration of contaminants, is an environmentally friendly approach to soil remediation. In this research, the interaction between copper and Pseudomonas fluorescents.was investigated. The study findings indicated a notable influence of copper concentrations on diverse parameters, encompassing bacterial growth, root length, dry mass, and root volume. The investigation delved into the copper tolerance mechanisms deployed by Pseudomonas spp., discussing factors like metal efflux pumps and metal-binding proteins. These mechanisms enable bacteria to flourish in environments contaminated with copper. The research also highlighted the potential of Pseudomonas fluorescents.in mitigating the adverse effects of copper contamination on plant growth. The bacteria can mobilize, solubilize, or sequester copper, reducing its availability to plants. This has implications for improving plant health and crop yields in copper-contaminated soils. In conclusion, this study contributes valuable insights into the bioremediation of copper-polluted soil through the use of Pseudomonas fluorescents.The findings suggest that these bacteria have the potential to play a crucial role in environmental remediation efforts and sustainable agriculture practices.
