Carbon-fixing microbes are engineered bacteria that enhance their ability to capture and convert atmospheric carbon dioxide (CO2) into biodegradable polymers through genetic modifications.
Addressing atmospheric CO2 levels by providing a biological method for capturing and storing CO2, potentially reducing greenhouse gas emissions and mitigating climate change impacts.
These microbes have been genetically engineered to overexpress the RuBisCO enzyme, which is crucial for CO2 fixation in photosynthesis. Additionally, their metabolic pathways are modified to increase the throughput of carbon capture and conversion into stable polymer structures, effectively sequestering CO2 from the atmosphere.
The manufacturing process involves genetic engineering of bacteria in bioreactors. This includes selecting bacterial strains, designing and inserting gene constructs, and scaling up production through fermentation processes.
Bacterial cultures are grown in bioreactors under controlled conditions to ensure optimal growth and expression of engineered genes. The process requires precise temperature control, nutrient management, and monitoring for efficient carbon fixation and polymer synthesis.
Field units draw low hundreds of watts; fabrication is energy-intensive due to vacuum baking and bioreactor operations.
