Ecotourism is growing business in Nepal due to domestic and international visitors. Specifically, natural lakes in Ramsar sites are very potential avenues for boating, scenic beauty and study the aquatic ecosystem. However Eichhornia crassipes has been threatening the beauty, ecosystem and eco-tourism business. This research was objectively carried out to explore income generation from ecotouri...

conserving water resources and protecting them from pollution are of high account in the natural cycle of our life. this study has tried to determine the refining potential and capacity of water hyacinth (eichhornia crassipes) in order to remove the cadmium from water, studying the influence of factors such as initial concentration of cadmium, contact time, absorbent mass, and ph. results have ...

Glutathione, a ubiquitous thiol-containing tripeptide is a low-molecular weight, water soluble antioxidant. It plays a major role in the removal of reactive species. Eichhornia crassipes is an aquatic weed possessing pharmacological potential and is a source of many antioxidants. HPLC established glutathione detection in E. crassipes was carried out with a PDA detector. The study revealed the p...

The ethanol extract of leaves and shoot portion of the fresh Eichhornia crassipes were screened for the presence of various phytochemicals by standard procedures. The present study indicates that the fresh plant contain alkaloids, flavonoids, phenols, sterols, terpenoids, anthoquinones and protein. The aqueous, chloroform fractionates and the ethanol and ethyl acetate extracts were screened for...

The main goal of this research was to quantify the concentrations of total and ammonium N, nitrate, total and soluble P in the water in the presence of Eichhornia crassipes and Salvinia auriculata, which were submitted to two different photoperiods in a 24 hours incubation period in the laboratory. The macrophytes were incubated in plastic vials of approximately 1.5 litters, with a previously p...

Cornops aquaticum is a widely distributed semiaquatic grasshopper in the Neotropics. The development, feeding and oviposition of C. aquaticum take place on Pontederiaceae, especially on species of Eichhornia. Several aspects of the feeding of C. aquaticum are studied because is one of the most important herbivores of the highly invasive floating Eichhornia crassipes in native areas. The aims of...

nanomaterials (nms) are widely used in health and biomedical applications, however, only a few studies investigate their toxic effects.  the present report signifies a contribution to the study of the toxic effects of silver nanoparticles (ag nps)  on   e. coli cells, which is a model organism of anthropogenic pollution. the toxicity of nanoparticles depends on their  chemical and surface prope...

To evaluate effects of environmental conditions on the abundance and communities of three denitrifying genes coding for nitrite (nirK, nirS) reductase and nitrous oxide (nosZ) reductase on the roots of Eichhornia crassipes from 11 rivers flowing into the northern part of Dianchi Lake. The results showed that the abundance and community composition of denitrifying genes on E. crassipes root vari...

There are many examples of cryptic species that have been identified through DNA-barcoding or other genetic techniques. There are, however, very few confirmations of cryptic species being reproductively isolated. This study presents one of the few cases of cryptic species that has been confirmed to be reproductively isolated and therefore true species according to the biological species concept...

A study was performed to evaluate capability of aquatic macrophyte Eichhornia crassipes plants to combat oxidative stress caused by tannery effluent treatment. For this purpose, tannery effluent was collected from “Up flow Anaerobic Sludge Blanket” (UASB) Jajmau, Kanpur. Plants of Eichhornia crassipes were exposed to various concentrations of tannery effluent (0.0, 25, 50, 75 and 100%) for 2 an...
