Abstract—

Molecular biology techniques have been applied to study the diversity and biomass of metabolically active prokaryotic cells in an oil-contaminated oligotrophic peat soil at different levels of mineral nutrition. The share of metabolically active components in the peat samples is only about 10% of the entire prokaryotic community. The application of mineral fertilizer (N₄₀P₅₀K₅₀) against the background of half-dose liming has led to a more than twofold increase in the biomass of bacterial and archaeal cells, an increase in the number of functional genes (bss and nifH) copies, and a significant decrease in the content of oil products in the peat of experimental variants. The application of mineral fertilizer against the background liming of oil-to contaminated soil induces changes in the phylogenetic structure and partial restoration of the metabolically active prokaryotic complex.

不同矿物质营养水平下受油污染的寡养泥炭土的原核成分：生物量，多样性和活性

摘要-

分子生物学技术已被用于研究不同矿物质营养水平的油污染的贫营养泥炭土中代谢活性原核细胞的多样性和生物量。泥炭样品中代谢活性成分的份额仅为整个原核生物群落的约10％。在半剂量浸灰的背景下施用矿物肥料（N ₄₀ P ₅₀ K ₅₀）导致细菌和古细菌细胞的生物量增加了两倍以上，功能基因（bss和nifH）的数量增加了）副本，并且实验变种的泥炭中石油产品的含量显着下降。矿物肥料在油污土壤的背景下施用会引起系统发育结构的变化和代谢活性原核生物复合体的部分恢复。
