The efficiency of a series of wetland colonized with Eichhornia crassipes and Salvinia molesta to treat the effluent of a giant river prawn (Macrobrachium rosenbergii) broodstock pond was evaluated in this study. The experimental design was completely randomized and was performed in 9 rectangular tanks (1.6 m3) with three treatments (constructed wetlands) and three replicates. The treatment typ...

We compared the effect of herbivory by two congeneric specialist weevils (Neochetina eichhorniae and Neochetina bruchi) on competition between their host Eichhornia crassipes and another floating aquatic plant (Pistia stratiotes) by experimentally manipulating plant densities, presence of either or both herbivore species, and nutrient levels. Measurements of E. crassipes yield per original plan...

Introducción. El lirio acuático (Eichhornia crassipes) es una planta hidrófita libre flotante de la familia Pontederiaceae. Es las plantas acuáticas con mejor reproducción y tasa crecimiento, por lo cual se extiende forma tapetes o esteras que constriñen a nativas sumergidas flotantes, disminuye entrada luz en los cuerpos agua el oxígeno disuelto agua. Objetivo. Realizar revisión bibliográfica ...

Research has been done on simultaneous saccharification and fermentation of water hyacinth (Eichhornia crassipes (Mart.) Solms.) with different pH to produce bioethanol. Simultaneous saccharification and fermentation process was the integration between saccharification or hydrolysis of cellulose into sugar and fermentation of sugar into ethanol, with utilized microorganism of Trichoderma harzia...

Sulfated polysaccharides (SP) are found mainly in seaweeds and animals. To date, they have only been found in six plants and all inhabit saline environments. Furthermore, there are no reports of SP in freshwater or terrestrial plants. As such, this study investigated the presence of SP in freshwaters Eichhornia crassipes, Egeria densa, Egeria naja, Cabomba caroliniana, Hydrocotyle bonariensis a...

Eichhornia azurea and E. crassipes are morphologically easy to distinguish, however, their seeds similar differentiated only by size, which makes identification difficult, especially when collected directly from the seedbank. We identified characters for distinguish of these species through macrosculpture analyzes seed coat (size, shape, epidermal pattern, structure primary secondary microsculp...
