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.

Aquaculture is vital for global food security, yet cemented ponds often face challenges related to poor water quality and low natural productivity owing the absence of bottom soil. This study investigates use vermicompost, a nutrient-rich organic fertilizer, enhance increase plankton production in aquaculture systems. The experimental design involved four tanks: control (Without fertilizer) three treatments with varying vermicompost application rates (5,000, 10,000, 15,000 kg/ha/yr). Assessments parameters—including dissolved oxygen, pH, ammonia levels—were conducted, along sampling abundance species composition. Results indicated improvements quality, particularly DO levels, highest observed treatment receiving kg/ha/yr vermicompost. Additionally, diversity (Diversity index) increased higher applications, notably enhancing phytoplankton groups, Chlorophyta, while maintaining stable zooplankton populations. These findings suggest that promising sustainable alternative chemical fertilizers, effectively improving fostering healthier aquatic ecosystem, thereby supporting productivity. Future research should explore long-term effects various settings.

Nature-based solutions represent a decentralized wastewater treatment proposal, offering diverse mechanisms for effectively removing emerging contaminants, particularly acidic pharmaceuticals. This study evaluated the performance of acidic-drug (diclofenac, fenofibrate, ibuprofen, gemfibrozil, fenoprofen, naproxen, and indomethacin) removal from using surface-flow constructed wetland with an organic bed (Eichhornia crassipes (Mart.) Solms, 18 ind/m2), horizontal subsurface-flow wetland, divided into three sections. The process was complemented by two stabilization ponds other wetlands papyrus (Cyperus L., 8–13 ind/m2) tezontle as support media. industrial-scale system (67.8 m2) fed at rate 1.33 m3/d hydraulic time retention about 5.8 days. Drugs were quantified gas chromatography. results showed that gemfibrozil indomethacin completely removed (100%), while diclofenac (73%) naproxen (94%) significant removals. Fenoprofen not removed. Ibuprofen fenofibrate increased concentrations, resulting in negative removals due to anoxic conditions (ibuprofen) slightly neutral pH (fenofibrate). These findings underscore system’s ability improve water quality most drugs, suggesting hybrid design is effective treating specific contaminants.

Eichhornia crassipes, commonly known as water hyacinth, is a highly invasive aquatic plant that poses significant ecological and socio-economic challenges worldwide. Its rapid proliferation depletes oxygen levels in bodies, obstructs waterways, disrupts biodiversity, accelerates siltation, thereby threatening ecosystems human livelihoods. Despite these negative impacts, hyacinth also offers promising opportunities for sustainable utilization due to its rich biochemical composition. It has potential applications bioenergy production, biofertilizers, wastewater treatment, pharmaceutical research, cardboard manufacturing, briquette production an alternative fuel source. This study explores the dual nature of emphasizing both environmental threats economic potential. By assessing innovative management strategies harnessing bioactive compounds, this research aims contribute solutions mitigate effects while promoting constructive use. A comprehensive understanding impact value can inform policy decisions integrated balance control efforts with resource
