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 ...

The objective of this research was to evaluate the performance of the aquatic macrophyte Eichhornia crassipes applied in situ in a slaughter house treatment system, located in the west of the Paraná state, Brazil, regarding the nutrients removal and organic matter. Moreover, it aimed to obtain data from the production, management and composting practices of the biomass generated in the system. ...

The aim of the current study was to investigate the potential of an aquatic plant, the water hyacinth (Eichhornia crassipes) devoid rhizospheric bacteria, to reduce naphthalene (a polyaromatic hydrocarbon) present in wastewater and wetlands. The capability of sterile water hyacinth plants to remove naphthalene from water and wastewater was studied in batch systems. Water hyacinths enhance the r...

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...

Eichhornia crassipes (Mart) Solms is an invasive weed known to out-compete native plants and negatively affect microbes including phytoplankton. The spread and population density of E. crassipes will be favored by global warming. The aim here was to identify compounds that underlie the effects on microbes. The entire plant of E. crassipes was collected from El Zomor canal, River Nile (Egypt), w...

The genus Pseudoheptascelio Szabó is redescribed and its species revised. We recognize four species: Pseudoheptascelio muesebecki Szabó, Pseudoheptascelio cornopis Masner, Pseudoheptascelio ticosp. n. and Pseudoheptascelio rexsp. n. The genus is found from Guatemala south to the Brazilian state of Rio Grande do Sul. The species Pseudoheptascelio cornopis is recorded as a parasitoid of the eggs ...

The Eichhornia crassipes macrophyte, also known as water hyacinth, is considered an invasive species due to its adaptability to a wide variety of ecosystems, affecting the natural balance of lagoons, lakes and so on Vankar & Vásquez [1,2]. An example of this is their strong presence in contaminated wetlands such as the yellow Juan of the city of Bogotá, where they removed almost 30 tons in 2016...

This paper deals with variations in biomass and in the production of Eichhornia crassipes (water hyacinth) in a eutrophic tropical reservoir. Net production was assessed by both a traditional method and a demographic approach. The initial biomass ranges from 96 g DW.m-2 to a maximum of 2027 g DW.m-2. Net production estimates varied greatly according to which method was used to calculate them (t...
