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.

This study was undertaken to assess the performance of constructed wetland coupled microbial fuel cell (CW-MFC) system treat real tannery wastewater. Five identically designed CW-MFC systems were setup and operated in a batch mode for two operational cycles. To effect filling media, CW1-MFC CW2-MFC filled with polypropylene granules as an innovative whereby, CW3-MFC, CW4-MFC, CW5-MFC packed natural gravel. All CW-MFCs provided cylindrical graphite anodes, but CW2-MFC, used irregular-shaped granular underneath anodes supportive auxiliary anode. Cana indica utilized vegetation model four systems, maintained unplanted considered control system. The results demonstrated that maximum removal efficiencies COD range 98.9%–99.3 %, while, power outputs recorded 351.3, 622.3, 538, 4437 mW/m3 salinity elimination 62 56 52 % CW1-MFC, WC3-MFC, WC4-MFC, respectively. Performance significantly comparable planted CW4-MFC regard generation, lower efficiency 16.43 indicating plant role total dissolved solids. Also, revealed absence arsenic chromium treated effluent. So, besides being effective approach treatment wastewater, it is promising, operationally friendly economically sustainable ecotechnology focus wastewater reclamation its reuse, well energy recovery.
