Article Synopsis
- Widespread oil contamination in soil poses significant risks to microbial life, making it crucial to examine how microbes respond to oil-induced stress and how this affects soil health.
- The study focused on the long-term impact of oil on soil's biochemical properties, comparing metabolite profiles of contaminated and non-contaminated soil, indicating detrimental effects on soil biological activity and increased production of toxic metabolites by fungi.
- Findings revealed that oil contamination significantly alters the metabolic profiles, with a decrease in carbohydrate metabolites and an increase in organic acids, phenolic compounds, and terpenoids, highlighting the impact of oil on soil quality and informing future recovery efforts for affected ecosystems.
Although bioaugmentation is known as effective and environmentally friendly method increasing removal of hydrocarbons from oil-contaminated soil, it sometimes fails in soil restoration and disturbs the ecological state of soil. We studied possible scenarios of the introduction of oil-degrading bacteria into oil-contaminated podzolic soil assessing the environmental safety of different bacterial preparations in a long-term field experiment. Integral indicators characterizing the state of biocenosis included biological activity of soil and aboveground biomass of grasses.
