Background: The study was undertaken to determine the phytochemical screening and the antibacterial activities of Pistia stratiotes (water lettuce) against some clinically isolated fish pathogens. Methods: The healthy and disease free plants samples were collected from Jebba Upper Basin of River Niger and tested for their antibacterial activities and phytochemical properties. Pistia stratiotes ...

L-Ascorbic acid (AsA) and its metabolic precursors give rise to oxalic acid (OxA) found in calcium oxalate crystals in specialized crystal idioblast cells in plants; however, it is not known if AsA and OxA are synthesized within the crystal idioblast cell or transported in from surrounding mesophyll cells. Isolated developing crystal idioblasts from Pistia stratiotes were used to study the path...

The female pupa was the only known preimaginal stage of Cryptotylus unicolor (Coscarón & Poi de Neiff 1996). From larvae collected on Pistia stratiotes (repollito de agua) in lagoons of Chaco geographic area, we obtained mature larvae, pupae and imagoes of both sexes of C. unicolor. From the same place we collected another larva that changed to the pupa stage in the laboratory, emerging finally...

Tingginya kadar fosfat, BOD, dan COD disebabkan oleh pembuangan limbah dari kegiatan laundry ke dalam badan air tanpa pengolahan yang memadai. Penelitian ini bertujuan untuk mengurangi dengan menggunakan berbagai jenis tanaman. Tanaman digunakan penelitian meliputi Pistia stratiotes, Salvinia molesta, serta kombinasi kedua tanaman tersebut. Metode eksperimen adalah sistem batch. Hasil menunjukk...

Cadmium (Cd) pollution is an environmental problem worldwide. Phytoremediation is a convenient method of removing Cd from both soil and water, but its efficiency is still low, especially in aquatic environments. Scientists have been trying to improve the ability of plants to absorb and accumulate Cd based on interactions between plants and Cd, especially the mechanism by which plants resist Cd....

The use of dead, dried aquatic plants, for water removal of metals derived from industrial activities as a simple biosorbent material has been increasing in the last years. The mechanism of simultaneous metal removal (Cd2+, Ni2+, Cu2+, Zn2+ and Pb2+) by 3 macrophytes biomass (Spirodela intermedia, Lemna minor and Pistia stratiotes) was investigated. L. minor biomass presented the highest mean r...

High arsenic (As) concentrations are toxic to all the living organisms and the cellular response to this metalloid requires the involvement of cell signaling agents, such as nitric oxide (NO). The As toxicity and NO signaling were analyzed in Pistia stratiotes leaves. Plants were exposed to four treatments, for 24 h: control; SNP [sodium nitroprusside (NO donor); 0.1 mg L-1]; As (1.5 mg L-1) an...

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...

Maggot (Hermetia illucens) is one type of alternative feed from Black Soldier Fly that easy to cultivate, economical and profitable reduce the rate aquaculture production cost. The purpose this study was determine growth maggot as carp (Cyprinus carpio) on growing medium apu (Pistia stratiotes). Research conducted March April 2022, using Complete Randomized Design method with 5 treatments 3 rep...
