Degradation of spiked pyrene and non-pyrene hydrocarbons in soil microcosms by Pseudomonas species isolated from petroleum polluted soils. Petroleum Science and Technology, 31(16), 1674-1680.https://doi.org/10.1080/10916466.2010.551240http://repository.elizadeuniversity.edu.ng/handle/20.500.12398/120The abilities of three Pseudomonads, Pseudomonas sp. strain LP1, Pseudomonas aeruginosa LP5 and P. aeruginosa LP6 to survive and enhance the degradation of pyrene and non-pyrene hydrocarbons in soil were tested in field-moist microcosms. All three organisms were able to survive and maintain high densities > × 107 in soil. In sterilized soils inoculated with bacterial isolates, 37.34%, 50.30%, and 42.21% were degraded by LP1, LP5, and LP6, respectively. The rates of pyrene degradation in soil microcosms were 0.046, 0.041, and 0.061 mg kg−1 h−1 for LP1, LP5, and LP6, respectively. A mixture of the three isolated degraded 7.73% was degraded in sterilized soil and 87.65% in native unsterilized soil (NS). The isolates also degraded non-pyrene hydrocarbon in the soils by more than 80%. The potentials these pseudomonads isolates for use as seed for bioremediation was successfully demonstrated.enBioaugmentationMicrocosmPseudomonasPyreneBiodegradationArticle
