ENGINEERING MICROBIAL SYNTHETIC BIOLOGY SYSTEMS FOR CARBON CAPTURE AND ENVIRONMENTAL RESTORATION

Abstract

Background: The increase of carbon dioxide emissions into the atmosphere and environmental pollution are the main reasons for climate change and ecological degradation. The development of engineered metabolic pathways and programmable microbial systems has emerged as a promising approach for sustainable carbon capture and environmental restoration in microbial synthetic biology.

Objective: To evaluate the efficiency of designed microbial synthetic biology systems for enhanced carbon sequestration, pollutant degradation and environmental restoration.

Methodology: Experimental analyses were performed using genetically engineered cyanobacteria, algae and bacterial strains engineered by CRISPR-based genome engineering, synthetic promoter regulation and metabolic pathway optimization. Under controlled laboratory conditions, carbon fixation efficiency, biomass production, pollutant degradation and environmental adaptability were evaluated.

Results: Engineered microbial systems demonstrated a 64% increase in carbon capture efficiency and a 52% increase in pollutant degradation compared to non-engineered strains. Increased photosynthetic activity and optimized metabolic pathways led to considerably enhanced biomass production and improved tolerance to environmental stress.

Conclusion: Microbial synthetic biology systems are promising and sustainable solutions designed and engineered for carbon capture and ecological restoration. The integration of synthetic biology, computational modeling, and precision bioengineering may accelerate future climate mitigation and environmental sustainability applications.
