The increasing demand for heavy metals in modern industries emphasizes the urgent need for sustainable and efficient metal recovery methods. Conventional mining and recycling techniques are environmentally damaging, energy-intensive, and often inefficient. Microbial metal recovery offers a promising alternative, leveraging microorganisms to extract and detoxify metal ions. However, widespread industrial adoption is hindered by challenges related to efficiency, specificity, and adaptability to complex environmental conditions. This project aims to develop a genetically engineered Pseudomonas putida system that integrates highly specific and tunable metal biosensors with surface-displayed metal-binding for enhanced metal recovery. The biosensors, based on metal-responsive transcription factors, enable real-time detection and dynamic regulation of gene expression, reducing metabolic burden while improving selectivity and efficiency. Surface display-based recovery strategies will further optimize metal sequestration, mitigating toxicity issues and enhancing microbial resilience in mixed-metal environments. By combining sensing and action, this research advances fundamental knowledge in metal-responsive transcription factors, paving the way for the development of scalable, autonomous recovery technologies that simultaneously recover valuable metals and mitigate environmental contamination.
