“The contamination of soil and groundwater from leachate leakage from landfill has turned, nowadays, into a global public issue. One of the main concerns about this pollutant is the potential threat to human and ecosystem health. The current research studied endophyte bacteria in association with poplar trees (Populus sp.), as a method of bioremediation of landfill leachates. The objective of the project was to identify treatment strategies that may improve plant performance (survival rates, plant fitness, and degradation efficacy) with the purpose of being implemented in phytoremediation plots, aimed to intercept and treat landfill leachate, before the contamination of watershed. This study focused on the ability of endophyte strains to colonize and thrive in symbiotic relations with Poplar trees and their impact on plant health. The health of the plant was measured by growth and contaminant degradation, while colonization was monitored using molecular biology and microscopy techniques. The results of this study were inconclusive but trends indicated some benefits to the plant when using endophytes together with biochar”--Abstract, page iii.
