Biodegradation of central intermediate compounds produced from biodegradation of aromatic compounds

Abstract

In this study I consider the incomplete biodegradation of aromatic compounds during the waste- water cycle between aerobic or anaerobic zones in biological nutrient removal processes, including aerobic biodegradation of compounds (such as cyclohex-l-ene-1-carboxyl-CoA) produced during the incomplete anaerobic biodegradation of aromatic compounds, and anaerobic biodegradation of compounds (such as catechol, protocatechuate, and gentisic acid) produced during the incomplete aerobic biodegradation of aromatic compounds. Anaerobic degradation of the aerobic central intermediates that result from the incomplete aero-bic degradation of aromatic compounds usually leads to benzoyl-CoA. On the other hand, aerobic degradation of the anaerobic central intermediates that result from the incomplete anaerobic degradation of aromatic compounds usually leads to protocatechuate.
