Isolation and characterization of an anaerobic syntrophic benzoate-degrading bacterium from sewage sludge

An investigation is reported which extends the range of known syntrophic bacteria to those which degrade some aromatic compounds. An anaerobic, motile, Gram-negative, rod-shaped bacterium has been isolated in coculture with hydrogen-utilizing Desulphovibrio sp. and Methanospirillum hungatei. The bac...

Description
Summary:An investigation is reported which extends the range of known syntrophic bacteria to those which degrade some aromatic compounds. An anaerobic, motile, Gram-negative, rod-shaped bacterium has been isolated in coculture with hydrogen-utilizing Desulphovibrio sp. and Methanospirillum hungatei. The bacterium degrades benzoates to acetates and carbon dioxide and hydrogen, or formate. The degradation reactions show standard free energy changes which indicate that the conversion of benzoate to methanogenic precursors would be expected to depend on removal of hydrogen for methane production by the methanogen. The bacterium was isolated from a municipal primary, anaerobic sewage digester and does not appear to grow on any compound other than benzoate.
