Salvinia exhibit capacity for removing contaminants such as heavy metals, inorganic nutrients, explosives from wastewaters. Properties such as high productivity, high sorption capacity and high metal removal potential establish Salvinia as an aquatic fern with immense potential for use in phytoremediation technologies. Realizing capabilities of Salvinia, its role for mass scale use in phytoreme...

Giant Salvinia (Salvinia molesta) is one of the world’s most invasive aquatic weeds. We evaluated the accuracy of airborne multispectral digital video imagery for separating giant salvinia from other aquatic and terrestrial features at a study site located in northeast, Texas. The five-band multispectral digital video imagery was subjected to an unsupervised computer analysis to derive a themat...

Giant salvinia (Salvinia molesta Mitchell) is a nuisance, free-floating aquatic fern that can double biomass in 10 days through vegetative reproduction. Hydrilla (Hydrilla verticillata (L.f.) Royle) is a perennial submersed aquatic plant that can propagate from stem fragments, turions, and subterranean tubers representing a triple threat for management methods. Both plants disrupt water bodies ...

Waterhyacinth ( Eichhornia crassipes [Mart.] Solms) and common salvinia ( Salvinia minima Baker) are two floating aquatic plants that can cause wide-spread problems in the southern United States. These species can cause reductions in ecosystem function as well as the abundance of native plant species. Herbicides are often used in an attempt to control both species; however, few recommendations ...

Giant salvinia (Salvinia molesta) is one of the most noxious invasive species in the world. Our bioactivity-guided fractionation of ethanol extract of giant salvinia led to the isolation of 50 compounds. Of the six new compounds (1-6), salviniol (1) is a rare abietane diterpene with a new ferruginol-menthol coupled skeleton and both salviniside I (2) and salviniside II (3) are novel benzofuran ...

Ammonium Preference: Agrostis canina (velvet bentgrass) Amphibolis antarctica (a seagrass) Callitriche hamulata (a water starwort) Ceratophyllum demersum (hornwort) Cymodocea rotundata (a seagrass) Drepanocladus fluitans (an aquatic moss) Eichhornia crassipes (water hyacinth) Elodea densa (Anacharis) Elodea nuttallii (Western waterweed) Fontinalis antipyretica (willow moss) Halodule uninervis (...

The cleanup of accidental oil spills in water is an enormous challenge; conventional oil sorbents absorb large amounts of water in addition to oil and other cleanup methods can cause secondary pollution. In contrast, fresh leaves of the aquatic ferns Salvinia are superhydrophobic and superoleophilic, and can selectively absorb oil while repelling water. These selective wetting properties are op...

Textile industries are one of the major contaminators of water and soil. Sodium is the only major cation present in textile wastewater due to high consumption of sodium salts in processing units. Many aquatic macrophytes are successfully used for phytoremediation of contaminated water. An attempt has been made to test the potential of Salvinia molesta in reduction of sodium from textile effluen...

batch adsorption experiments were performed to study adsorption potential of agricultural residues viz. rice straw, wheat straw and salvinia plant biomass for removal of heavy metals such as cr, ni, and cd. plant materials were used in different combinations. heavy metal removal efficiency was more at low metal concentration (35 mg/l). salvinia biomass possessed higher efficiency for removing h...

27 In the present study, the effect of phosphate ion and iron hydroxides (Fe-plaques) on the 28 selective uptake of arsenic species by water fern (Salvinia natans L.) was investigated. The 29 plants were grown for 5 days in aqueous Murashige and Skoog (MS) culture media modified in 30 arsenic and phosphate concentrations. Arsenic accumulations in Salvinia natans L. increased 31 with the increas...
