Abstract:A phenanthrene-utilizing bacterium was anaerobically isolated and identified as Rhodopseudomonas palustris. It tolerated up to 100 mg phenanthrene l-1 and degraded 50% of 50 mg phenanthrene l-1 over 10 days. The presence of phenanthrene caused a prolonged lag phase (2–3 days) in cell growth and affected the photopigments biosynthesis, while DMSO (the solvent for phenanthrene) had no impact on cell growth. The cell surface hydrophobicity of the isolate was also increased.
