Biodegradation of Homocyclic and Heterocyclic Aromatic Compounds by Rhodopseudomonas palustris Strains

Authors: GÖNÜL ÇETİNKAYA DÖNMEZ, AYTEN ÖZTÜRK

Abstract: Six strains were isolated from Lake Aksehir (Konya-Turkey) and identified as Rhodopseudomonas palustris on the basis of physiological and morphological characteristics. The strains grew phototrophically on a variety of aromatic compounds (under illuminated anaerobic conditions), namely, benzoate, hippurate, benzyl alcohol, 2-amino benzoic acid, phloroglucinol, phenylacetic acid, catechol, pyridine and pyrazoline. Biodegradation of 2-amino benzoate, phloroglucinol, catechol, pyridine and pyrazolin by Rhodopseudomonas palustrisstrains have not been reported in the literature.

Keywords: Rhodopseudomonas palustris,aromatic compounds, biodegradation.
