Carbonic anhydrase as a tool to mitigate global warming.

Area of Science:

• Biotechnology and Environmental Science
• Biocatalysis for Carbon Capture

Background:

• Global average temperatures are rising due to increased CO2 emissions, necessitating urgent climate change mitigation.
• Carbon capture and sequestration (CCS) is a key technology, with carbonic anhydrase (CA) showing significant potential.
• Conventional CCS methods face challenges, driving research into more efficient biocatalytic approaches.

Purpose of the Study:

• To review carbonic anhydrases (CAs) and their role in CO2 sequestration.
• To explore recent advancements in CA immobilization strategies for industrial applications.
• To highlight the advantages of CA-based CCS over traditional methods.

Main Methods:

• Review of literature on various types of CAs, their characteristics, and sources.
• Analysis of recent developments in CA immobilization techniques.
• Evaluation of CA stability and reusability in simulated industrial conditions.

Main Results:

• Carbonic anhydrase (CA) efficiently catalyzes the conversion of CO2 and water.
• Extremophilic microbial CAs show promise for stability under harsh operational conditions.
• Immobilization of CA on support materials improves stability, reusability, and cost-effectiveness for CO2 sequestration.

Conclusions:

• CA-based CCS is a viable and advantageous technology for mitigating climate change.
• Immobilization is crucial for the practical, large-scale industrial application of CAs in CO2 sequestration.
• Further research into extremophilic CAs and novel immobilization methods is warranted.
