Microbial denitrogenation of fossil fuels

摘要

The microbial degradation of nitrogen compounds from fossil fuels is important because of the contribution these con- taminants make to the formation of nitrogen oxides (NO_x) and hence to air pollution and acid rain. They also contribute to catalyst poisoning during the refining of crude oil, thus reducing process yields. We review the current status of microbial degradation of aromatic nitrogen compounds and discuss the potential of microbial processes to alleviate these problems.
