The aim of this research was to investigate the overall dynamics and the efficiency of
biodegradation of saturated and aromatic compounds – constituents of the oil pollutant,
during ex situ bioremediation of the polluted soil.
The effect of natural biodegradation was investigated in a parallel set of samples of
the same soil which was not subjected to the processes of stimulation (bioaugmentation,
biostimulation and aeration).
During the period of six months, the biodegradation process caused a gradual and
prominent degradation of phenanthrene, dibenzothiophene, fluoranthene/pyrene and their
alkyl homologues. Among the polycyclic aromatic hydrocarbons (PAHs), distributions
and abundances of benz(a)anthracene/chrysenes and triaromatic steroids were the least affected by biodegradation. n-Alkanes and isoprenoids remained low in abundances
during and until the end of the experiment, indicating that the availability, rather than the
biodegradability, was responsible for removal ...of these compounds.
In the set of the samples exposed to the stimulated bioremediation, within the
homologue series of phenanthrenes, dibenzothiophenes and fluoranthene/pyrenes, higher
alkylated homologues were more degradable than the lower ones. Additionally, lower
alkylated homologues were more degradable than their parent molecules. These results
are opposite to those described in the literature and indicate that a proper choice of
bioremediation conditions can influence biodegradation sequences of the compounds
present in the pollutant. Furthermore, these results showed that the extent of
biodegradation in the samples exposed to stimulation was much higher than in the
samples where only natural biodegradation occurred, pointing that the stimulated
biodegradation is much more efficient process than the natural biodegradation.
