Summary

Major air pollutants that can be degraded biologically include both volatile organic as well as inorganic compounds. Bioprocesses are not suitable for the removal of particle matter. The biodegradation routes depend on the nature of the pollutants. End-products are generally water and carbon dioxide under aerobic conditions, but other products may appear as well. Acids such as hydrogen chloride and sulphuric acid will be formed from the aerobic biodegradation of, respectively, halogenated and most sulphur-compounds. If oxygen is limiting, elemental sulphur may accumulate during the biodegradation of sulphur-pollutants. Anaerobic biodegradation of waste gases will yield different metabolites. Recent research trends have also been dealing with the biotransformation, rather than biodegradation, of volatile pollutants. This offers the possibility to convert volatile compounds to useful, value-added metabolites such as (bio)fuels to cite only one example.
