Аннотация:Abstract—A model experiment has been performed on the successive aerobic and anaerobic degradation of
oil products in samples of oilcontaminated peat sampled from a pine–subshrub–sphagnum bog near the
Sutormin oilfield pipeline in the YamalNenets autonomous district. During the incubation of oilcontami
nated peat with lime and mineral fertilizers under complete flooding, favorable conditions are created for the
aerobic oxidation of oil products at the beginning of the experiment and, as the redox potential decreases, for
the anaerobic degradation of oil products conjugated with the reduction of N5+ and S+6 and methanogenesis.
From the experimental data on the dynamics of the pH; Eh; and the NO3-,NO2- , and SO42- concentrations
in the liquid phase of the samples, it has been found that denitrifiers significantly contributed to the biodeg
radation of oil products under the experimental conditions. After the end of the experiment, the content of
oil products in the contaminated samples decreased by 21–26%.
