This study aims to investigate how multi-microbial inoculants (rhizobacteria and mycorrhizal fungi) enhance pollutant removal and plant health in the Point Fraser constructed wetlands, Western Australia. Experiments will involve native wetland plants inoculated with microbial consortia and grown in contaminated substrates containing nutrients and heavy metals. Parameters such as pollutant concentrations, microbial enzymatic activity, radial oxygen loss, root exudation, and plant biomass will be measured. The expected outcome is the identification of synergistic plant-microbe combinations that significantly improve phytoremediation efficiency, soil health, and plant growth, providing a scalable and sustainable framework for ecological restoration and pollution mitigation.
