Description:
Pseudomonas paucimobilis strain EPA505, was previously purified from a 7-membered bacterial community originally isolated from a creosote-contaminated soil for its ability to degrade polycyclic aromatic hydrocarbon (PAH) components of creosote. The unique ability of this organism to utilize fluoranthene as sole source of carbon and energy for growth in pure culture was demonstrated by increase in bacterial biomass, change in UV-absorption spectrum of fluoranthene, decrease in aqueous fluoranthene concentration, and the production of metabolites when fluoranthene was as sole carbon source in liquid culture. hereas primary utilization of fluoranthene appears to involve previously undefined variations on established oxygenation and ring cleavage processes, findings suggest the potential for accelerating the biotransformation of other environmental pollutants currently considered recalcitrant to microbiological attack. Hence, strain EPA505 and other organisms similarly isolated for their ability to degrade fluoranthene and related compounds may prove useful to remediation efforts employing biological processes.
