Dual carbon sequestration with photosynthetic living materials.

ABSTRACT: Natural ecosystems offer efficient pathways for carbon sequestration, serving as a resilient approach to remove CO₂ from the atmosphere with minimal environmental impact. However, the control of living systems outside of their native environments is often challenging. Here, we engineered a photosynthetic living material for dual CO₂ sequestration by immobilizing photosynthetic microorganisms within a printable polymeric network. The carbon concentrating mechanism of the cyanobacteria enabled accumulation of CO₂ within the cell, resulting in biomass production. Additionally, the metabolic production of OH^- ions in the surrounding medium created an environment for the formation of insoluble carbonates via microbially-induced calcium carbonate preci
