| The microbiological
enzymatic oxidation of a hydrocarbon results in a fatty acid or
carboxylic acid. When microbes biodegrade hydrocarbons, the following
chemical reaction occurs.
decane to decanoic acid

benzene rings to catechol
  
These fatty or carboxylic
acids are then further broken down for energy and carbon by beta oxidation,
which removes two carbon atoms at a time as follows. -- oxygen requirement for
the first step of bioremediation to a fatty acid is minimal, requiring only 2
or 4 atoms per hydrocarbon molecule.
R-C-C-C-COOH R-C-COOH + C-COOH CITRIC ACID CYCLE
The two carbon atoms are accepted in the
citric acid cycle that produces energy and carbon for protein. Final end
products of hydrocarbon biodegradation are energy, protoplasm, carbon dioxide,
and water. |
