Inhaltsangabe:
- <p>Soil health is an integral determinant of agricultural productivity, ecosystem balance, and environmental<br>sustainability. Microbial biosensors, leveraging genetically engineered microbial strains, offer a novel approach to real-time, in<br>situ monitoring of soil contaminants and nutrient dynamics. These biosensors are designed to detect specific chemical signals—<br>ranging from heavy metals and pesticides to changes in pH and nitrogen content—by producing measurable outputs such as<br>fluorescence, bioluminescence, or electrochemical signals. This article reviews the development and deployment of microbial<br>biosensors as tools for assessing soil health. It explores their underlying biological principles, integration into environmental<br>monitoring frameworks, and potential to overcome the limitations of conventional soil assessment techniques. The paper<br>emphasizes the importance of synthetic biology and CRISPR-based modulation in enhancing biosensor specificity and stability.<br>Furthermore, it highlights successful case studies from agriculture, bioremediation, and land reclamation projects. Finally, the<br>article discusses current challenges—such as environmental variability and regulatory hurdles—and future directions, including<br>field-deployable biosensor platforms and wireless data integration. The findings underscore microbial biosensors’ transformative<br>potential in advancing precision agriculture and soil restoration practices through continuous and targeted ecological<br>surveillance.</p>
