Challenges and Opportunities of Using Functional Materials To Inspire Anaerobic Biotechnology

Area of Science:

• Environmental biotechnology
• Materials science
• Anaerobic digestion

Background:

• Emerging functional materials show potential for wastewater treatment but lack widespread environmental application.
• Anaerobic biological systems are crucial for sustainable wastewater treatment.
• A gap exists between material innovation and practical environmental biotechnology implementation.

Purpose of the Study:

• To summarize functional materials that can enhance environmental biotechnology based on their energy sources.
• To discuss mechanisms for improving interspecies and extracellular electron transfer.
• To identify challenges and suitable scenarios for functional material applications in wastewater treatment.

Main Methods:

• Literature review and synthesis of existing research on functional materials in anaerobic systems.
• Categorization of functional materials into 'internal' and 'external' types.
• Analysis of mechanisms influencing microbial metabolism, interspecies interactions, and electron transfer.

Main Results:

• Internal functional materials enhance microbial metabolic processes by facilitating interspecies interactions.
• External functional materials mediate energy exchange with the environment.
• Understanding electron transfer mechanisms is key to optimizing microbial metabolism.

Conclusions:

• Functional materials offer significant potential for advancing wastewater treatment technologies.
• Rational design of functional materials, potentially using AI, is needed for large-scale engineering applications.
• Bridging the gap between material science and environmental biotechnology requires addressing practical application challenges.
