Bioremediation approaches for oil contaminated soils in extremely high-mountainous conditions
Development of methods for bioremediation of soils contaminated with petroleum products is one of the most urgent tasks of our time. This task is more difficult to perform in high-mountainous landscapes, at an altitude of more than 4 000 m a.s.l. Moreover, these high-mountain ecosystems are the most...

| description | Development of methods for bioremediation of soils contaminated with petroleum products is one of the most urgent tasks of our time. This task is more difficult to perform in high-mountainous landscapes, at an altitude of more than 4 000 m a.s.l. Moreover, these high-mountain ecosystems are the most vulnerable to various kinds of anthropogenic impacts, and therefore the relevance of bioremediation is obvious. The research was conducted in the high-altitude ecosystems of the Kyrgyz Republic at the Kumtor mine. In this study was carried out on the bioremediation of oil contaminated soil using biostimulation, bioaugmentation and biostimulation + bioaugmentation remediation techniques for 90 days in the climatic conditions of high mountain region. The biostimulation treatment showed the highest total petroleum hydrocarbons (TPH) biodegradation percentage 62.78% compared to the bioaugmentation 50.63% and biostimulation + bioaugmentation 49.11%. Thus, the method of biostimulation proved to be the most effective method for bioremediation of soils contaminated with petroleum products. The application of this method could be one of the successful methods of recycling contaminated soils. This study demonstrated the possibility of restoring TPH-polluted soils using biological methods of soil treatment in climatic cold conditions of high mountains. |
