This study investigates microbial community structures in landfill soils, focusing on fungal and bacterial compositions in aged (closed), active (operating), and leachate leakage zones, compared to a pristine zone. Molecular approaches revealed that bacterial phyla were most abundant in active landfill soil, particularly Actinobacteria (0.63-fold), Firmicutes (0.17-fold), and α-Proteobacteria (0.13-fold), while Nitrospira, Acidobacteria, and Chloroflexi were minimal. The results indicate a correlation between bacterial groups and landfill zone age. Additionally, the type of buried waste, including medical and municipal solid waste, significantly affected fungal diversity and abundance in surface soil layers.
