duckweed vs azolla nutrition



most of which stem from the collection of E. Landolt, ETH, Zürich, Switzerland, were maintained under axenic conditions on agar. Conserving and restoring ecosystem states should account for potential trade‐offs between ecosystem services and preserving the natural value of shallow lakes. Means ± standard deviations are given. AA, amino acids; AAS, amino acid score; Ala, alanine; ALA. ic acid; Cys, cysteine; DW, dry weight; EAA. Composition et valeur nutritive des aliments pour animaux au Burundi. Rural Dev., 2 (2): 15-22. Luthria, D. L., Lu, Y., & John, K. M. M. (2015). 20–30. HPLC analysis of carotenoids was performed with a, vitamin E, an aliquot of the solution extracted with methanol/, tetrahydrofuran was evaporated under nitrogen stream and, HPLC analysis was performed with a diol column (column temper-, Freeze-dried duckweeds were used to extract lipids by acceler-, ated solvent extraction (ASE) according to, which, the internal standard cholestanol-D, solvent was removed by a gentle stream of nitrogen. Higher rate of photosynthesis seems to be a determining factor for higher RGR. This was mainly caused by the, -linolenic acid, which was between 11 and 25%, -linolenic acid was present only in small amounts or, even close to the detectable limits. Basak et al., 2002; Datta et al., 2011; Domínguez et al., 1996; Gavina, 1994; Khatun et al., 1999; Kumar et al., 2012; Leterme et al., 2010; Naegel, 1997; Namra et al., 2010. biochemistry to clinical implications in cardiovascular prevention. Survey of the total fatty acid and triacylglycerol composition and content of 30. The quantitative, determination of AA in duckweed samples was based on the, chemical properties of the proteinogenic AA. Taxonomy of duckweeds (Lemnaceae). Edelman, M., & Colt, M. (2016). An x/y representation of data for lysine and methionine content highlights the group differences between grains, pulses, leafy vegetables, and animal foods. Quantitation of c, fatty acids in dairy products and cod liver oil by mass spectrometry in the, Jahreis, G., Brese, M., Leiterer, M., Schaefer, U., & Böhm, V. (2016). Molecular weights of duckweed protein fractions ranged from 14 kDa to more than 160 kDa. Many duckweeds and Azolla have been suitable for human consumption as health food supplement [7, ... One potential protein alternative is duckweed (Lemna minor). Nutritional improvement of ensiled rice straw through supplementation of urea, molasses, soybean seed meal and aquatic plants. Species of the genus Wolffia (duckweed) are harvested from natural water bodies in many countries for human consumption. Bioactive phytochemicals in wheat: Extraction, analysis, processing, and functional properties. Rapeseed oils for human nutrition are offered as refined edible oil with 00-quality, as a cold-pressed edible oil, and as HOLLi quality oil, very low α-linolenic acid of 3%. Effect of Azolla (Azolla pinnata) based concentrate mixture on nutrient utilization in buffalo bulls. This plant has the ability to reproduce rapidly, it can double in just 16 hours - 2 days, depending on its growing environment. Buckingham, K. W. ; Ela, S. W. ; Morris, J. G. ; Goldman, C. R., 1978. Protein fractionation and in vitro digestibility of Azolla in ruminants. Studies investigating risk assessment established that the enrichment of food and feed with DHA- and/or EPA-rich sources may lead to an intake of n-3 fatty acids in humans fourfold greater than the recommended level. Nevertheless, nitrate content never exceeded 530 mg NO3 kg-1 fresh weight. Accordingly, W. hyalina and W. microscopica are recommended for human nutrition. In China for example, it has been grown in rice paddies between seasons since ancient times. Becerra, M. ; Murgueitio, E. ; Reyes, G. ; Preston, T. R., 1990. In contrast, the content of polyunsaturated fatty acids, . The concentration of PUFA was given as, 61–64% TFA and the ratio n6/n3 could be calculated from their data, as 0.23–0.29. in sows. 4.8% Lys, 2.7% Met + Cys, and 7.7% Phe + Tyr. ... Because of high nutritional properties, duckweed and Azolla are suitable for feeding a wide range of animals like broiler chicken, goats, sheeps, cattle, rams, buffalo calves, pigs, rabbits, horses, waterfowls, fishes, etc. Furthermore, violaxanthin, zeaxanthin, β-carotene, chlorophylls a and b were quantified. Taken together, strain H3 dominantly colonized duckweed for a short period and improved duckweed growth. It was found that nitrate levels increased with the increasing availability of macronutrients in the water, and pH showed a particularly strong negative correlation with the nitrate levels in the plant. (2015). Laboratory data 1963-1991. Basak, B. ; Pramanik, A. H. ; Rahman, M. S. ; Tarafdar, S. U. ; Roy, B. C., 2002. In all the species, investigated, the content of n3 fatty acids was surprisingly higher, than the content of n6 fatty acids. However, as stressed by, to be considered before it can be commercially marketed as human, food. A good source to clone the required genes from a plant is the moss Physcomitrella patens with Iipids containing up to 30% ARA and some EPA (Grimsley et al., 1981). Introduction: Plant nutrition and growth is an important part of life. They were exposed to continuous white light at, (photosynthetically active radiation) from fluo-, medium for four weeks during this pre-cultivation phase in order, to ensure reproducible results. The highest content was found, as in case of protein con-, under cultivation conditions different from that in the present pro-, with glucose (i.e. Duckweed science and food excursion in. Duckweeds are increasingly gaining interest because of their potential as a new aquaculture crop. The harvested plants, as the value-added by-products, can be used as biofuels [14,15]. Sci., 1 (1/3): 29-34. The nutrition taken up by plants is what makes them grow efficiently. Nutrient value of leaf vs. seed. ... Azolla (Azolla pinnata) and Duckweed (Spirodela polyrhiza) have several versatile properties which make them suitable for nutritive supplement to humans, animal feeds, bio-fertilizer, biofuel, waste water treatment, bio-indicator, etc. Thereafter, biomass was harvested, Fresh duckweeds were analysed for dry weight (DW). With the rapid growth of global population, and the associated need for amino acids, duckweeds offer 20% to 45% of protein, consistent with WHO recommended amino acid intakes, ... High-protein content and adequate essential amino acids and vitamins make duckweed an attractive plant alternative for protein production. http://dx.doi.org/10.1016/j.foodchem.2016. (A) Dry weight, (B) Total protein content, (C) Fatty acid content, (D) Starch content. Join ResearchGate to find the people and research you need to help your work. For some duckweed is a menace, for others it's a Godsend. Production of high-starch. Phytosterols—Health benefits and potential, Lahive, E., O’Callaghan, M. J. This species is rather rare in Thailand, sold in the market for human consumption from Northern, Thailand in 2016, and identified all of them as, these authors dealt with the more common species, carbohydrate, and fat content of these plants and reported that, ‘‘Khai-nam” was used as food of poor people for many generations, in Laos, Thailand and Burma (now Myanmar). Feedipedia is an open access information system on animal feed resources that provides information on nature, occurrence, chemical composition, nutritional value and safe use of nearly 1400 worldwide livestock feeds. A comparison of the amino acid composition of duck-. Res. It has been already, reported that members of Wolffioideae (the present study included, late in the free form unlike the other duckweed genera which form, the use of Wolffioideae members as human food. Sci. In legume flours the n6/n3 ratio was determined to, be as high as 4.6 (lupine), 5.7 (green pea), and 21.8 (chickpea), and in common edible plant oils, the n6/n3 ratio showed a high, variation from 0.28 in flax seed and 2.2 in rapeseed up to 15 in, oil, hardly any n6 fatty acid could be detected. This article is protected by copyright. The study's results showed that duckweed culture on the media with high contents of DS or EFL was impossible because they both inhibited its growth. Applied Ecology and Environmental Research. Selenium accumulation differed between species, and sulphate reduced selenium uptake in both species indicating that ionic constituents, in particular sulphate, are important in modifying selenium uptake by primary producers. is collected from ponds and ditches and fed to pigs and ducks. Namra, M. M. M. ; Hataba, N. A. ; Wahed, H. M. A., 2010. Positive nutrition and environmental information decreased acceptability of non-fitting meals. All figure content in this area was uploaded by Gerhard Jahreis, All content in this area was uploaded by Gerhard Jahreis on Mar 08, 2017, Nutritional value of duckweeds (Lemnaceae) as human food, University of Jena, Institute of General Botany and Plant Physiology, 07743 Jena, Germany, Central University of Kerala, Department of Environmental Science, RSTC, Padannakad, Kerala 671314, India, University of Jena, Institute of Nutrition, Jena, Germany, University of Hohenheim, Institute of Food Chemistry, Stuttgart, Germany, Thuringian State Institute of Agriculture, Jena, Germany. Owing to the amino acid composition, the total protein of duck-, weeds qualifies as a high quality protein source for human nutri-, tion. Refined and cold-pressed rapeseed oils are valuable because of their high α-linolenic acid content, about 10%, their low saturated fatty acid content, about 6%, and their optimal n-6:n-3 ratio of 2:1. This is confirmed by phytotoxicity investigations in duckweed by. R A Leng, J H Stambolie and R Bell . (2014) Bazh EK, El-Bahy NM.. "In vitro and in vivo screening of anthelmintic … Duckweed (Lemna minor L) is a rich source of nutrients that can be exploited to meet dietary requirements in humans. The Age-Related Eye Disease Study 2 (AREDS2) Randomized. The main objective of Feedipedia is to provide extension and development workers, planners, project formulators, livestock farmers, science managers, policy makers, students and researchers with the latest scientific information to help them identify, characterize and properly use feed resources to sustainably develop the livestock sector. Moreover, plant proteins have a favorable effect on lipid metabolism. However, the lack of information on duckweed protein as a bioenergy coproduct limits its use. weeds, given as an average of all six presently investigated species, with earlier results of four duckweed species (, as well as with the amino acid composition of soya and chickpea, indicates that the amino acid composition in duckweeds is compa-, rable with that of other plant proteins and it should be stressed, that in no case the content of critical amino acids in duckweeds, mendation. o acid index; essential AA/non-essential AA. This paper focuses on the attributes that duckweed has which make it a special contender as a protein source for chickens. elements were determined using the following techniques: calcium, phosphorus, magnesium, sodium, potassium, iron, copper, zinc, and manganese with ICP-AES; arsenic, hydride-AAS, mercury with cold vapour AAS by direct mercury, analyser, cadmium, lead with graphite furnace AAS and iodine after, To determine the contents of carotenoids and vitamin E, the, freeze dried duckweed samples were extracted three times under, an ultra turrax. and Salvinia molesta Mitchell.) We assume that this significant, difference was caused by the mixotrophic cultivation conditions, conditions because mixotrophic conditions are not useful. (2015). According to the, higher than 5. Steinberg medium, specified by the ISO 20079 protocol, however, a modified Schenk-Hildebrandt medium was employed with the, The main phase of cultivation used for determining the biomass, composition employed the same conditions as described for the, plates were used. A., & Kennedy, C. J. In the present investigation, 0.5. Macro and micro elements in Wolffia microscopica. Without added glucose these authors reported starch content to be, only 29%. VerglichenHygiene mit unseren Vorfahren leben wir in einer eher sterilen Welt. glucose, which is impractical from a biotechnological point of view. Since the publication of the fundamental monograph on Lemnaceae by E. Landolt in 1986, a number of changes have taken place in terms of their taxonomic position and nomenclature, which we summarize in this review. The highest content of protein was found in soya and lupin, which both contained ca. • Here, we identify major shallow lake ecosystem services and their links to Sustainable Development Goals (SDGs), compare service provisioning among the four ecosystem states and discuss potential trade‐offs. Aquaculture, 310 (3/4): 376-379. Sree, K. S., & Appenroth, K.-J. Morphology, ion uptake, and starch accumulation. Duckweed - a potential high-protein feed resource for domestic animals and fish . Additionally, one sample was treated via HPP at 200, 400 and 600 MPa for 5, 10 and 40 min at room temperature. Species of the duckweed genera, Spirodela, Landoltia, Lemna, Wolffiella and Wolffia were analysed for protein, fat, and starch contents as well as their amino acid and fatty acid distribution. Abstract. The content of polyunsaturated fatty acids was between 48 and 71% and the high content of n3 fatty acids resulted in a favourable n6/n3 ratio of 0.5 or less. The phytosterol content in the fastest growing angiosperm, W. microscopica, was 50 mg g⁻¹ lipid. The fat content in legume flours other than soya flour was clearly under 10 g/100 g. The omega-6/omega-3 ratio in lupin and green pea flour was in accordance with the recommended maximal ratio of 5:1. The shrimp ate some for sure, but I also think allelopathy was part of it. Nutritional value and intake of aquatic ferns (Azolla filiculoides Lam. Data (B–D) are related to dry weight. [7. Rate of photosynthesis (oxygen production in light) and respiration (oxygen consumption in dark) in clones of W. globosa, measured under standardized conditions, are in positive correlation with their respective RGR. Lemnoideae are a family of tiny flowering plants that float on the surface of fresh water. May 16, 2019 Duckweed and azolla therefore have great protein content – (on a par with soyabeans, peas and lupins) if raised correctly and can double their biomass in 2 to 3 days. At present Lemnaceae comprises of 37 species grouped into five genera. identify fatty acid peaks/: No. The perspective ends with a discussion on “So why do we eat mainly seeds?”. Predicting selenium bioaccumulation is complicated because site-specific conditions, including the ionic composition of water, affect the bioconcentration of inorganic selenium into the food web. The biosynthesis of Δ5-unsaturated VLCPUFA occurs through sequential desaturation and chain-elongation in many eukaryotic organisms, but not in angiosperm, In most pollen, carbohydrates constitute the major dry matter fraction (Table 8-1). The injector and detector temperatures. During these processes, microorganisms play an important role in promoting duckweed growth and improving its tolerance to stresses. This is not fulfilled with at least some of the legume, at the molecular level indicate that human beings evolved on a diet, with an n6/n3 ratio of essential fatty acids (EFA) of, Western diets the ratio is 15:1–16.7:1. acceptance as nutritive human food source. The protein content of freeze-dried duckweeds was calculated, via the Kjeldahl procedure using the N factor 6.25. The content of saturated fatty, acids (mainly palmitic acid, followed by lignoceric acid) was rela-, tively high, that of monounsaturated fatty acids (mainly based on, oleic acid) and of SCFA and MCFA was very low. (1st ed., pp. This article is protected by copyright. These little plants are incredible because they reproduce asexually, which means that they just bud off one each other. (2016).
