Article Synopsis
- Abandoned brownfields present significant challenges for recovery, and using sustainable remediation methods like bioremediation relies on the understanding of indigenous microorganisms in contaminated soils.
- A metagenomic study revealed diverse microbial communities in polluted soils but showed a decline in diversity in heavily contaminated areas, specifically where mercury and arsenic levels were highest.
- The research identified unique groups of archaea and fungi that thrive in extreme conditions, suggesting these microorganisms play key roles in detoxifying pollutants, which is essential for developing effective remediation strategies.
An innovative combination of metagenomic profiling of microbial communities and GC-MS & Pyrolysis-GC-MS fingerprinting methods were used to assess the biodegradation of contaminated soil from the Burgan oil field in Kuwait. The soil was treated with (sludge) compost in microcosms to evaluate the feasibility of this material for bioremediation purposes. The most favourable trial showed a > 80% decrease in TPH, thereby indicating strong potential for full-scale application using a cost-effective technology and thus in line with the principles of the circular economy.

In some cases, this material alters the taxonomic and functional composition of the bacterial communities present in these matrices; however, there is no conclusive data that can be generalized to all scenarios. Here we studied the effect of nZVI application on groundwater from the site of an abandoned fertilizer factory in Asturias, Spain, mainly polluted with arsenic (As).
