Engineered marine bacteria continuously secreting siderophores to speed olivine weathering — a research article exploring reactor design, scalability, and deployment pathways.
Key Takeaways
- Engineering Alteromonas macleodii increased olivine dissolution rates 2.6-fold compared with unmodified strains
- Pilot-scale continuous reactors weathered 4 kg olivine using seawater and renewable acetate feedstock
- Reactors with engineered cells removed 0.50 g CO2 per day via alkalinity generation measured directly
