Abstract
Traversing the complex terrain of 21st-century environmental engineering grand challenges, the urgency to address global issues has reached unprecedented heights. The central focus of this research, aimed at advancing enzyme biodegradation, is firmly committed to addressing the grand challenges of ensuring sustainable and safe water supply while envisioning a future free from pollution. Motivated by the vast potential of enzyme catalysis for biodegradation, this research is dedicated to evaluating innovative approaches that safeguard and optimize enzymes across diverse environmental conditions. Despite recognizing the significant capabilities of oxidative enzymes in oxidizing prevalent and hazardous compounds, translating this potential into real-world applications remains a formidable challenge. The primary challenges range from specific requirements for enzyme catalysis, such as the lack of mediators, to more common issues, including stability, longevity, and production costs. Therefore, the paramount objective of this doctoral research is to advance the practical application of enzymes in biodegradation. This will be achieved through immobilization approaches, utilizing a co-immobilization technique to provide the necessary mediators for the enzyme manganese peroxidase to carry out oxidative reactions, while addressing stability. Additionally, this research aims to engineer synthetic bionanozymes inspired by laccase, a natural oxidative enzyme, to address other real-world challenges, such as expensive manufacturing and enzymes' limited longevity and stability. These dual pursuits aim to unlock new dimensions in enzyme biodegradation, offering a path towards sustainable and efficient solutions for combating environmental pollution and preserving the health of both human and environmental ecosystems. By elucidating the potential of enzyme-based technologies, this research aims to pave the way for a more sustainable and efficient approach to mitigating environmental pollution.
