- Treatment of air pollution: use of bacteria, fungi, algae, and plants.
- Bioreactors for air pollution control (biofilter, biotrickling filter, bioscrubber,…) and bioconversion processes.
- Prevention of air pollution: Production and upgrading of biofuels, such as (bio)hydrogen, biodiesel, (bio)ethanol, biogas, or desulfurized fuels.
- Waste gas and syngas (CO, CO2, H2) bioconversion.
- Carbon dioxide (CO2) capture or removal.
- Metabolic engineering and strain improvement.
