Recent Advancements in Carbonic Anhydrase–Driven Processes for CO₂ Sequestration: Minireview

Abstract

The authors reviews the advancements in carbonic anhydrase– driven processes for CO₂ sequestration research and engineering. Historical and recent discoveries of carbonic anhydrase and idea behind using it for CO₂ sequestration are elaborated as well as the uses of this enzyme in free and immobilized forms are thoroughly discussed. New concepts such as extension of immobilized enzyme systems for bioreactor approach with the aim of CO₂ abatement at the source are also introduced briefly toward the end of the review. The authors also suggest the possible future directions to employ carbonic anhydrase for CO₂ sequestration.

KEY WORDS:

• bioreactor
• carbonic anhydrase
• CO₂ sequestration
• enzyme immobilization
