Abstract
Molecular biological techniques and bioinformatic analysis were used to investigate the phylogenetic and functional diversity of the prokaryotic complex of soil microcosms. The dominant organisms of the hydrolytic community were different in the samples from different climatic zones. In the soils subject to anthropogenic or abiogenic load, apart from decreased diversity and abundance of prokaryotes, the number of the genes marking the ability to degrade xenobiotics, as well as those encoding nitrogen conversion and metabolism of vitamins and cofactors, was found to increase. Under heavy oil contamination, the bacterial community was capable of nitrification; its role increased in the lower horizons of the soil profile. The patterns revealed in the work indicate high metabolic potential of the prokaryotic component of the studied soils.
