This study investigated the microbial diversity inhabiting roots (rhizosphere) of macrophytes thriving along Blesbokspruit wetland, South Africa's least conserved Ramsar site. The wetland suffers from decades pollution mining wastewater, agriculture, and sewage. current focused on three macrophytes: Phragmites australis (common reed), Typha capensis (bulrush), Eichhornia crassipes (water hyacinth). results revealed a greater abundance microbes (Bacteria Fungi) associated with free-floating E. compared to P. T. capensis. Furthermore, correlation between metals, showed strong fungal communities metals such as nickel (Ni) arsenic (As), while bacterial correlated more lead (Pb) chromium (Cr). functional analysis predicted by PICRUSt2 identified genes related xenobiotic degradation, suggesting potential these break down pollutants. Moreover, specific groups - Proteobacteria, Verrucomicrobia, Cyanobacteria, Bacteroidetes were linked this degradation pathway. These findings suggest promising avenue for microbe-assisted phytoremediation, technique that utilizes plants their decontaminate polluted environments.

Phytoremediation is a strategy for the amelioration of soil heavy metal contamination that aligns with ecological sustainability principles. Among spectrum phytoremediation candidates, woody plants are considered particularly adept their substantial biomass, profound root systems, and non-participation in food chain. This study used Eucalyptus camaldulensis —a tree species characterized its high biomass rapid growth rate—to assess uptake mining tailings. The results were as follows: exposure to metals reduced E. potassium (K), phosphorus (P), calcium (Ca). Heavy stress negatively affected . Lead (Pb) primarily accumulated roots, while cadmium (Cd) predominantly stems. application organic fertilizers bolstered tolerance , mitigating adverse impacts stress. A synergistic effect occurred when combined bacterial fertilizers. plant’s enrichment capacity Cd Pb was augmented through concurrent Collectively, improved by enhancing K, P, Ca elevating content glutathione peroxidase (GPX) gibberellin acid (GA) roots. These findings provided nascent groundwork breeding enhanced tolerance. Moreover, this proved potentiality management metal-contaminated tailings offers promising avenue future environmental restoration.
