Biofixation of carbon dioxide (CO2) by microorganisms
C.Q. Lan, University of Ottawa, Canada
Microbial biofixation of carbon dioxide (CO2) employs the capacity of autotrophic microorganisms, including photoautotrophs and chemoautotrophs, to fix CO2 for cell growth to reduce CO2 emission. In general, there are two approaches towards microbial CO2 sequestration: enhancing the biological productivity of autotrophs in their natural habitats (e.g., ocean fertilization) and cultivating autotrophic microorganisms in controlled systems (e.g., microalgal farming). This approach is effective, environment friendly and potentially sustainable. It is predicted that rapid technology development will make microbial CO2 bio-sequestration ...
