Megamelus scutellaris Berg (Hemiptera: Delphacidae) is a South American species that feeds on waterhyacinth, Eichhornia crassipes Mart. (Solms). This species exhibits significant wing dimorphism whereby fully winged adults (macropters) are capable of flight while those with reduced wings (brachtypters) are not. The wing form is determined by a developmental switch triggered by environmental fac...

Xiphidorus amazonensis n. sp. was found in the rhizospheres of Jatropha curcas, Musa sp., Anona muricata, Cassia tora, Panicum laxum, Paspalum fasciculatum, Aeschynomene sensitiva, Saccharum officinarum, Manihot esculenta, Abelmoschus esculentus, Tamarindus indica, Mangifera indica, Vigna unguiculata, Zea mays, Commelina sp., Cyperus rotundus, Fimbristylis miliacea, Citrus sinensis, and Eichhor...

A freshwater plant, water hyacinth (Eichhornia crassipes) is commonly found in public waters Indonesia. Water often experiences blooming which causes negative impacts such as lowering oxygen levels, reducing the number of fish, increasing evapotranspiration, disrupting transportation, becoming habitat for disease vectors, and others. However, can be used an alternative raw material because it s...

Land areas which are wet during part or all of the year are referred as wetlands. Constructed wetlands are manmade systems that mimic the functions of natural wetlands and applied for wastewater treatment. Aim of the present study is to investigate the feasibility of using a macrophytes, Eichhornia crassipes in constructed wetland for treatment of wastewater in an institutional complex. The dai...

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 wastewater at Sukinda chromite mines (SCM) area of Orissa (India) showed high levels of toxic hexavalent chromium (Cr VI). Wastewater from chromium-contaminated mines exhibit potential threats for biotic community in the vicinity. The aim of the present investigation is to develop a suitable phytoremediation technology for the effective removal of toxic hexavalent chromium from mines wastew...

This study presents bioconversion of water hyacinth (Eichhornia crassipes) to bioethanol using two-sequential steps of acid hydrolysis (10% sulfuric acid) and yeast (Candida intermedia) fermentation. Maximum ethanol yield co-efficient was comparable to those obtained through enzymatic saccharification and fermentation of acid hydrolysate using fully equipped fermentor. A maximum ethanol yield (...

This study aimed to explore the effectiveness potential of Eichhornia crassipes, Pistia stratiotes and Salvinia molesta for reduction potentially toxic metals from effluents enriched with Cd, Cr Pb. Based on a 21-day laboratory-scale experiment, total three concentrations at 1, 5 10 mg/L were selected culture each macrophytes. In addition, kinetics prediction models used analyze metal data unde...
