Actions of a versatile fluorene-degrading bacterial isolate on polycyclic aromatic compounds

Article Abstract:

The bacterium Pseudomonas cepacia F297 may be able to break down fluorene and various other polycyclic aromatic compounds (PACs), such as phenanthrene, anthracene, and naphthalene. The F297 strain grew in the presence of various PACs, using them as a source for carbon. After incubating the bacteria in a mixture of PACs and creosote for 14 days, the concentration of PACs dropped. The reactions the bacteria use to break down the PACs are discussed.

Bacterial community dynamics and polycyclic aromatic hydrocarbon degradation during bioremediation of heavily creosote-contaminated soil

Article Abstract:

Bacterial community dynamics and biodegradation processes are examined in a highly creosote-contaminated soil undergoing a range of laboratory-based bioremediation treatment. Results suggest that there are complex interactions between bacterial species and medium conditions that influence the biodegradation capacity of the microbial communities involved in bioremediation processes.

Identification of a novel metabolite in the degradation of pyrene by Mycobacteruim sp. strain AP1: actions of the isolate on two- and three-ring polycyclic aromatic hydrocarbons

Article Abstract:

Mycobacterium sp. strain AP1 can metabolize pyrene via a newly described reaction that produces 6,6'-dihydroxy-2,2'-biphenyl dicarboxylic acid as an intermediate. Pyrene is the most common polycyclic aromatic hydrocarbon in the environment, and this bacterium could be used to degrade it.
