Engineered yeast for enhanced CO₂ mineralization.

ABSTRACT: In this work, a biologically catalyzed CO₂ mineralization process for the capture of CO₂ from point sources was designed, constructed at a laboratory scale, and, using standard chemical process scale-up protocols, was modeled and evaluated at an industrial scale. A yeast display system in Saccharomyces cerevisae was used to screen several carbonic anhydrase isoforms and mineralization peptides for their impact on CO₂ hydration, CaCO₃ mineralization, and particle settling rate. Enhanced rates for each of these steps in the CaCO₃ mineralization process were confirmed using quantitative techniques in lab-scale measurements. The effect of these enhanced rates on the CO₂ capture cost in an industrial scale CO₂ m
