AI Article Synopsis
- Addressing environmental contamination from heavy metals and organic pollutants is vital, and this study focused on the ability of Pleurotus ostreatus GEMB-PO1 to remove copper effectively.
- The fungus demonstrated significant tolerance to copper and removed 64.56% at lower concentrations, but its efficiency dropped when copper levels increased, showing a complex response at the transcriptomic level with enzyme upregulation.
- A dual remediation system using P. ostreatus GEMB-PO1 improved organic pollutant degradation, but the effectiveness of copper removal decreased, highlighting the need for further research to optimize the removal of both types of contaminants.
Article Abstract
Addressing the environmental contamination from heavy metals and organic pollutants remains a critical challenge. This study explored the resilience and removal potential of Pleurotus ostreatus GEMB-PO1 for copper. P. ostreatus GEMB-PO1 showed significant tolerance, withstanding copper concentrations up to 2 mM. Its copper removal efficiency ranged from 64.56 % at 0.5 mM to 22.90 % at 8 mM. Transcriptomic insights into its response to copper revealed a marked upregulation in xenobiotic degradation-related enzymes, such as laccase and type II peroxidases. Building on these findings, a co-remediation system using P. ostreatus GEMB-PO1 was developed to remove both copper and organic pollutants. While this approach significantly enhanced the degradation efficiency of organic contaminants, it concurrently exhibited a diminished efficacy in copper removal within the composite system. This study underscores the potential of P. ostreatus GEMB-PO1 in environmental remediation. Nevertheless, further investigation is required to optimize the simultaneous removal of organic pollutants and copper.
