“…The 100% treatment concentration had the highest removal efficiency of 69% and 94% for both phosphate and nitrate respectively (figure 4 and 5). Several authors have observed that E. crassipes in aquaculture wastewater treatment not only reduce the nitrate and phosphate concentrations but also store these excess nutrients in its root and shoot system (Osti et al, 2020;Ayanda et al, 2020;Nizam et al, 2020;Kutty et al, 2009). E. crassipes root area provides a large absorption surface, favoring the process of sedimentation and development of root-associated biofilm (Grajales et al, 2020 andSipaúba-Tavares et al, 2002).…”

Aquaculture production has seen much increase in Nigeria in recent times due to the rise in fish farming occasioned by the availability of water and materials for setting up, the profit turn-over, increase in demand for fish, and the effort to curb the rising youth unemployment rate. However, this massive surge of interest in aquaculture and fish farming is accompanied by the challenge of pollution as the effluent from aquacultural settings gets discharged into nearby water bodies hence the need for remediation. Aquatic plants have been used to remediate polluted water bodies and possess many advantages over other methods. Therefore, this study aimed to investigate the effectiveness of Eichhornia crassipes in the clean-up of aquaculture effluent. Wastewater collected from a commercial fish pond in Benin City, Nigeria, were divided into two treatment groups. One group was diluted with an equal volume of distilled water (50%), and the other group consisted of 100% wastewater. Distilled water was used as a control (0%). The samples were treated with Eichhornia crassipes for 14 days, following which samples were collected for physicochemical analysis. The result showed that E. crassipes reduced significantly the pH from 7.44 to 5.98 and 7.28 to 6.10 in the 50% and 100% effluent samples, respectively. The removal efficiency of E. crassipes in the 100% effluent sample was 69% for phosphate, and 94% for nitrate. The study suggests that E. crassipes may be effective in improving the quality of aquaculture wastewater.

BackgroundEichhornia crassipes (E. crassipes) have several secondary metabolites that have medicinal value. These include sterols, alkaloids, phenolics, flavonoids, tannins, and saponins. In the current study, the methanolic petiole extract of E. crassipes was examined to determine its potential antiproliferative activity against Sloan Kettering Melanoma 5 (SK-Mel-5) cell lines. Materials and methodsEichhornia crassipes were obtained from the water bodies of Ezhikkara, Ernakulam, Kerala. The Soxhlet technique was used to produce the extract. Leaves, petioles, and roots were dried and pulverized before being analyzed phytochemically in a number of solvents. The 3-(4,5-dimethylthiazol-2-yl)-2,5diphenyltetrazolium bromide (MTT) assay was used to measure the extent to which various dosages of the extract inhibited cell proliferation, and the methanolic extract of petioles was chosen since it contained more anticancer components. The half maximal inhibitory concentration (IC 50 ) was determined by utilizing a probit model and the slope-gradient method of the regression equation. The Statistical Package for Social Sciences (SPSS) version 21 (IBM SPSS Statistics, Armonk, NY) was used for the analysis. ResultsWe examined the effects of 12.5, 25, 50, 100, and 200 μg/ml of methanolic petiole extract. The data indicated that the methanol extract significantly reduced SK-Mel-5 cell viability. Cell growth inhibition increased with concentration but was shown to be relatively low at 100 g/ml, exhibiting 38.911% of inhibitory activity. The percentage of cell growth inhibition at 200 g/ml was 52.965%. The methanolic petiole extracts of E. crassipes were found to be cytotoxic with IC 50 values of 172.186 g/ml. Probit analysis was performed to obtain the regression equation. ConclusionThe in vitro study suggests that the methanol extract of the petiole of E. crassipes had modest antiproliferative action against SK-Mel-5 cells, a typical human melanocyte tumor cell line. The study findings shed light on the anticancer activity of E. crassipes, making it an appropriate source of drug-lead chemicals for the development of safer and cost-effective remedies for cutaneous ailments varying from rashes to awful melanoma.

Many lakes and rivers all over the globe are experiencing environmental, human health, and socio-economic development issues due to the spread of invasive water hyacinth (WH) weed. WH is regarded as one of the world’s most destructive weeds and is nearly impossible to control and eliminate due to its rapid expansion and ability to double its coverage area in 13 days or fewer. However, most people in developing countries appear to be hoping for a miraculous cure; there are none and never will be. In this regard, this chapter aims to give an insight to raise awareness, research its biology and challenges, management options, and potential prospects on integrated control-valorization and its policy implications. WH biomass has demonstrated potential as a biorefinery feedstock for bioenergy and biofertilizer production, heavy metal phytoremediation, handicraft and furniture making, animal feed, and other applications. As a result, large-scale integrated control and valorization is an economically viable strategy for preventing further infestation through incentivizing WH control: providing a sustainable environment, increasing energy mix, increasing fertilizer mix, increasing food security, reducing GHG emissions, boosting socio-economic development, and creating new green jobs for local and riparian communities. Therefore, it is a leap forward in addressing global sustainable development goals (SDGs) through the water-energy-food-ecosystem (WEFE) nexus.
