Abstract: Microbiological degradation of cinnamic acid and its hydroxyl-derivatives occurs via aerobic or anaerobic pathway. The first step in the biodegradation of these compounds, both aerobic and anaerobic, is β-oxidation. The key intermediate in this process is benzoyl-CoA. In anaerobic environment this intermediate can be transformed to acetyl-CoA, incorporated into the central metabolism. Under aerobic condition benzoyl-CoA is transformed to protocatechuate acid, gentisic acid or catechol, compounds which are cleaved by a specific dioxygenase. Many microorganisms can transform phenolic acid to an amino acid or other compounds such as which 4-hydroxybenzoic acid, amide, acetophenone, which can be used in industry.
