Summary:
This research paper deals with the evaluation of different technologies for the bioremediation of oil-contaminated soils. Among the methods considered are natural attenuation, bio-stimulation and bio-enhancement, using indigenous microorganisms in the first two cases and allochthonous ones in the latter. The main objective of this procedure is to observe the performance in correspondence to the reduction in oil concentration respectively to each method. The analytical methods used to monitor this reduction include pH measurement, solid residue measurement, metal determination by inductively coupled plasma optical emission spectrometry, calcination loss measurement, total oxidized carbon (Walkley Black) measurement, Dumas nitrogen measurement, detection of organic matter by gas chromatography coupled to a flame ionization detector and detection of crystalline phases by X-ray diffraction. Overall, the experimental procedure allowed us to differentiate the capacity and the rate of degradation between the methods used. The results, as well as the difficulties encountered during the experimental process, can be used to support similar types of experiments that aim to replicate and optimize or to investigate in-depth bioremediation processes.
