163,246-253. Turk. The study was conducted in the reactors planted with Lemna gibba L. plants. Growth of colonies is rapid, and the plants form a carpet covering still pools when conditions are suitable. The species is monoecious (individual flowers are either male or female, but both sexes can be found on the same plant). Lemna minor is a floating freshwater aquatic plant, with one, two, three or four leaves each having a single root hanging in the water. [28] Grown in swine lagoon diluted water, L. minor accumulates 10.6% starch of total dry weight. [21] An investigation showed, that the expensive sesame oil cakes in chicken diets could partially be replaced by cheap L. minor with increased growth performance of broiler. [12] Because L. minor is temperature tolerant, shows rapid growth and is easy to harvest, it bears high potential for the cost-efficient use in wastewater treatments. Ministère de l’Enseignement Supérieur et de la Recherche Scientifique. Lemna minor es el nombre botánico de esta especie perteneciente a la familia Araceae y es conocida de forma común como: lenteja de agua y lenteja de los acuarios. Specific identification of flat forms of the Lemna gibba/L. [13][14][15] Because heavy metals have carcinogenic effects in humans,[16] persist long in nature and accumulate in living organisms, their removal from the environment is important. Razafitsalama, M., Falihery R., Rakotondraibe, J., 2012. Lemna gibba, in gibbous form, was always the stronger competitor, being able to overgrow and shade out Lemna minor. [23], Lemna minor as fast growing, nitrogen and phosphorus accumulating aquatic plant with high nutritional value for livestock, finds another application in the nutrient recovery from livestock wastewater. Flowers are rarely produced and measure about 1 mm in diameter, with a cup-shaped membranous scale conta… Click below on a thumbnail map or name for species profiles. , 1998; Ater et al. Mercury and lead: assessing the toxic effects on growth and metal accumulation by Lemna minor. (Wang et al., 2002; Zayed et al., 1998). Valorisation d’une plante aquatique dénommée Lemna paucicaustata en épuration d‘eaux usées domestiques en pisciculture. L. minor grown in 50% D2O without addition of kinetin exhibited a lag phase twice that of H2O-grown controls, before start of log phase growth at 40% of control rates.

J. [32], Species of flowering plant in the family Araceae, Skillicorn P, Spira W and Journey W (1993), Duckweed aquaculture a new aquatic farming system for developing countries, The International Bank for Reconstruction and Development/The World Bank. They are morphologically divergent members of the arum family Araceae.These rapidly growing plants have found uses as a model system for studies in community ecology, basic plant biology, ecotoxicology, and production of biopharmaceuticals, and as a source of animal feeds for agriculture and aquaculture. [6], The fertilizer requirements for growing duckweed depend on the water source and the geographic isolate of L. minor that is used. Lemna minor synonyms, Lemna minor pronunciation, Lemna minor translation, English dictionary definition of Lemna minor. In experiment 1, four different manures were used. through anaerobic digestion in a UASB) of the wastewater and dilution of the liquid to below 100 mg/l total Kjeldahl nitrogen and 50 mg/l total phosphorus, led to the best performance regarding growth and nutrient removal. Merve, S., Amine, A.T., Erdal, O., Ahmet, S., 2015. [28], After harvesting, enzymatic hydrolysis releases up to 96.2% of starch bound glucose. The results showed that circulation of the waste water enhanced the kinetics of the process, as compared to the control systems. During the experiment, the water and plant samples were daily taken and the temperature, electric conductivity and pH of the water were … Phytomonitoring of pulverized fuel As leachates by the duckweed Lemna minor. Aquatic Sci., 4: 105–109. Organization for Economic Cooperation and Development Working Group on Waste Prevention and Recycling. In this study, laboratory tests were performed in order to examine growth characteristics of floating aquatic macrophytes (Lemna gibba and Lemna minor) in the presence of wastewater with circulation. Due to its low cellulose content (approximately 10%) compared to terrestrial plants, the conversion procedure of the starch to ethanol is relatively easy. Castanares, A. G. (1990). Journal of Hazardous Materials 330, 116-126. We developed efficient genetic transformation protocols for two species of duckweed, Lemna gibba (G3) and Lemna minor (8627 and 8744), using Agrobacterium-mediated gene transfer. Anaerobic pretreatment (e.g. Growing selected geographic isolates of L. minor on diluted swine lagoon liquid in North Carolina resulted in yields up to 28.5 g m−2 day−1 (104.03 t ha−1 y−1) and removal of over 85% of the total contained nitrogen and phosphorus. Lemna palustris Haenke ex Mert. Sus sinonimias son las siguientes: Hydrophace minor, Lemna cyclostasa, Lemna minima, Lemna minor var. In this study, the efficiency of Lemna gibba L. on tetracycline (TC) removal from the solutions prepared at various initial TC concentrations (50, 100 and 300 µg/L) was investigated. It doesn’t build up very complex tissue structures and therefore has a low fiber content less than 5%. The plants then become dormant and sink to the ground for overwintering. Lemna parodiana Giardelli Lenticula gibba (L.) Moench Lenticula gibbosa Renault Limna cordata Sesse & Moc. Iatrou E.I., Gatidou G., Damalas D., Thomaidis N.S., Stasinakis A.S.

En la comarca de Bages existen dos especies de lentejas de agua: Lemna minor y Lemna gibba. Comparison of lemna gibba and lemna minor from the production ecological viewpoint. oxymitra, Lemna monorhiza, Lemna ovata, Lemna palustris, Lemna rwandensis, Lemna … Velmi hojnou vodní rostlinou je okřehek menší (Lemna minor). 18. Un article de Wikipédia, l'encyclopédie libre. Lemna minor, commonly referred to as lesser duckweed or common duckweed, is a small, vascular, aquatic macrophyte belonging to the family Lemnaceae. Lemna gibba L. NATIVE Plant Body: generally in 2s or 3s; 3--6 mm, widely elliptic to round, glossy green or yellow-green mottled red, base symmetric, tip asymmetric, upper surface barely convex, midline bumps generally 0, lower surface generally convex, with enlarged air spaces often bordered in red.

This study aimed to assess the ability of two Lebanese duckweed species, (Lemna minor and L. gibba), to grow under in vitro conditions on three nutritive solutions, Murashige Skoog (MS), Schenk-Hildebrand (SH) and Algal Assay Procedure (AAP). Elle a été consommée par l'Homme, comme un légume cuit, par exemple cuite à la poêle, prenant alors selon L'ethnobotaniste François Couplan une saveur agréable[3]. Ecotoxicology Environment. Lemna minor has also been shown to remove organic micropollutants such as pharmaceuticals [18] and benzotriazoles [19] from wastewater. Lemna valdiviana is native in the Americas but has become invasive in parts of southern Europe (Iberite et al., 2011). [11] Another one says, that viable L. minor biomass removed 85-90% of Pb(NO3)2 with an initial concentration of 5 mg/l. The potential of Lemna gibba L. and Lemna minor L. to remove Cu, Pb, Zn, and As in gallery water in a mining area in Keban, Turkey. Andmat är en mycket liten vattenväxt som trots sin ringa storlek är lätt att hitta då den är flytande och växer i stora massor. Velmi hojnou vodní rostlinou je okřehek menÅ¡í (Lemna minor). Cette espèce était autrefois consommées par certains porcs et a été étudiée comme source de nourriture pour la pisciculture[2]. L −1 . The Lemna protein concentrate is a source of natural and sustainable essential nutrients, like proteins, vitamins and minerals. Cd and Cu were separately applied at concentrations of 0.01, 0.05, 0.1, … The water of those ponds then fertilizes bigger ponds on which L. minor is grown for the further use as fodder for ducks.[20]. Lemna gibba has the potential to clean Uranium and Arsenic contamination from mine surface waters ,it has been utilized for polishing in waste-water treatment and worldwide distribution of Lemna sp. [8] Sewage water, which often has an adequate concentration of potassium and phosphorus, can be used to grow duckweed, but nitrogen concentrations need to be adjusted.[9].
