ANAMMOX process was considered to be one of the most sustainable pathways for nitrogen removal from ammonium-rich wastewater. In cell clusters microbial cells were aggregated close to each other by EPSs and filamentous bacteria, and the cluster size varied from few to 200m. 224230, 2008. Glutamate is essential for a healthy brain, but the dose makes the poison. Another report surmised that sulfide might toxic to microorganisms [86]. 1, pp. 26522656, 2010. 943952, 2010. When too much glutamate accumulates in the brain, it becomes an excitotoxin a substance that literally stimulates brain cells to death. Physical exercise has been shown to optimize the balance between glutamate and GABA in people with depression. Kim, J. D. Lindsey et al., Elevated hydrostatic pressure triggers release of OPA1 and cytochrome C, and induces apoptotic cell death in differentiated RGC-5 cells, Molecular Vision, vol. Recent researches report postulated that Heme is the indispensible part of these key enzymes of ANAMMOX bacteria [106, 107] and the content of Heme might be involved in ANAMMOX activity and other relative activities [108]. The localization of GLAST1a is different from normally expressed GLAST, which is entirely expressed in the Mller cell body [34]. In the mouse Mller cells, glutamate removal by GLAST is calculated as 50% among the retinal glutamate transporters [25]. 93106, 2000. In this section, we give an overview of the relations between the energy supply and the glutamate metabolism. 20, no. By AJ Lotery, Eye, vol. 11611162, 2005. W. B. Thoreson and P.

The produced dinitrogen gas entrapped with ANAMMOX granules for maintaining a balance of production and release [114]. 11, no. EAAC-1. 8, pp. [14] discovered a new species called Anammoxoglobus sulfate which was the functional community in reactor to remove ammonium and sulfate concomitantly. 30293036, 2009. 4, pp. Boost your memory and your ability to learn. As glutamine synthetase consumes ATP to convert glutamate to glutamine [80], it seems plausible that ATP suppression in the ischemic retina [21] promptly induces the impairment of delegation of glutamate, resulting in the elevation of the extracellular concentration of glutamate. (ii)The well-settled granules accumulation in reactor contributes to the super high volumetric nitrogen removal rates even at extremely high NLRs and short HRTs. [14] reported that simultaneous removal process might be hindered if there is no coexistence of sulfate reducing bacteria and autotrophic ANAMMOX bacteria. It is considered that glutamine synthetase activity may be upregulated for a short period after onset of ischemia to protect retinal neurons against excitotoxicity. Glutamate is the most abundant neurotransmitter in the brain and central nervous system. 13121322, 2013. Chen et al. 4, pp. These results suggest that integrity of GLT-1 may be a prerequisite for the maintenance of glutamate homeostasis in the retina undergoing glaucoma [109]. Subunit or EPS-filamentous bacteria bands were segmented into several compartments which were called cell clusters. 153160, 2001. We earn revenue when you buy through our links, at no cost to you. 6, pp. Glutamate excess is primarily attributed to perturbation in the homeostasis of the glutamate metabolism.

In addition to their role as protein building blocks in living organisms, amino acids are used industrially in numerous ways. High loading rate favored the ANAMMOX sludge to produce huge amount of dinitrogen gas which could not be released outside of sludge through the tunnels due to clogging of gas tunnels [113]. In addition, immunoreactivity reveals the presence of EAAC-1-positive amacrine cells distant from the synaptic sites. 16, no. The monosodium salt of Sodium fluoride L-glutamic acid; used in the treatment of encephalopathies associated with liver diseases. Yang et al. [2] and 0.11g-VSS/g-N, van Dongen et al.

Vice versa some researchers used only (NH4)2SO4 as sole substrate in influent for N and S source [14]. Lorsquon le cuisine, il ne se dcompose pas, mais un brunissement ou des ractions de Maillard se produiront en prsence de sucres temprature leve, comme les autres acides amins[11]. Glutamate undergoes deamination, an oxidative reaction catalysed by glutamate dehydrogenase,[16] as follows: Ammonia (as ammonium) is then excreted predominantly as urea, synthesised in the liver. But three and six are more common. Based on these findings, transcriptional regulation and mRNA splicing causing differential expression of GLAST or GLT-1 may affect glutamate transport and may provide an complicated mechanism for glutamate uptake. However, knockdown of the expression of GLAST or GLT-1 in rats using antisense oligonucleotides increased the extracellular glutamate concentration, whereas EAAC-1 knockdown mice showed no increase in extracellular glutamate [42].

The floating granules were taken out of the reactor and broken into small pieces and returned into reactor to overcome the frequent floating problem of ANAMMOX sludge. Although glutamate is considered as a potent exotoxin, exogenous glutamate is only weakly toxic to the retina when glutamate transporters on Mller glial cells are operational [10]. 18, pp. It has been reported that the RGC loses the retrograde axonal transport by mechanical causes, resulting in apoptotic or necrotic cell death in the experimental glaucoma model induced by perilimbal and episcleral vein photocauterization [118]. Immunohistochemistry revealed that inhibition of glutamine synthetase by d,l-methionine,l-sulfoximine (MSO) caused a dramatic increase in the glutamate level in the Mller cells, and subsequently the rapid loss of the glutamate content of the photoreceptor cells, bipolar cells, and ganglion cells [8]. These results may indicate that during pressure-loading, impairment of GLAST takes place first, and results in downregulation of glutamine synthetase activity as a second effect. Q. Li and D. G.

N-pollution not only hampers the sustainable development of agriculture, fishery, tourism, and so forth but also threatens the living environment of human beings. Vitamin C is the most popular vitamin supplement, so you may have some around the house. The radical corresponding to glutamate is called glutamyl. Its most important role, by far, is as a neurotransmitter, a chemical messenger in your brain. L'agence alimentaire dAustralie et de Nouvelle-Zlande[22],[23] (FSANZ) cite un nombre de preuves consquent issues dun grand nombre dtudes scientifiques pour dmentir explicitement tout lien entre le glutamate monosodique et des ractions indsirables graves ou des effets durables, dclarant le glutamate monosodique inoffensif pour la population gnrale. In ischemia/reperfusion rat eyes, it actually takes several days to induce a significant depression of glutamine synthetase after the onset of the retinal ischemia [8284]. 181197, 2012. 1, pp. These results suggest that the expression of GLT-1c may represent an attempt by retinal ganglion cells to protect themselves against elevated levels of glutamate. In primary glaucoma in dogs [116], it is reported that decreases in glutamine synthetase immunoreactivity were associated with the damaged regions of the retina. 6330, pp. M. Persson and L.

[55] reported the genetic regulation of both genes Slc1a3 and Glul using an array of 75 recombinant inbred strains of mice. Northern blot analysis indicated a linear correlation between the reduction in glutamate synthetase expression and the time course of diabetic retinopathy, which was validated by real-time RT-PCR. 135144, 2011. 271282, 2010. The sulfate-dependent isolate used carbonate as carbon source, ammonium as energy and nitrogen source, and sulfate as electron acceptor. Major pathway of glutamate metabolism consists of glutamate uptake by glutamate transporters followed by enzymatic conversion of glutamate to nontoxic glutamine by glutamine synthetase. Vice-versa, these changing conditions play an important role to grow up large population of the species which only can adapt to this changing situation. [28] disclosed that the content of Heme increased significantly with the increasing NRR. 38533859, 2006. The reports of recent researches have been presented in Table 3. The floatation of ANAMMOX biofilm was extensively investigated and mechanism of sludge floatation (Figure 7) could be explained in three sequential phases [92] such as (i) formation of gas tunnel, (ii) formation of gas pocket and (iii) floatation of sludge granule. This indicated that SBA-ANAMMOX process could successfully overcome the toxic effects of refractory ammonium-rich pharmaceutical wastewater. J. Wang and J.-D.

In glaucoma, there was additional preferential expression of GLT-1c in retinal ganglion cells [36]. These results indicate the importance of maintaining the homeostasis of glutamate metabolism to prevent the excitotoxicity in retinal diseases such as the retinal ischemia, glaucoma, and diabetic retinopathy. The structure of a monosodium glutamate molecule is illustrated below. L. T. Macnab, S. M. Williams, and D. V. Pow, Expression of the exon 3 skipping form of GLAST, GLAST1a, in brain and retina, NeuroReport, vol. 19401944, 2000. Another important feature of free amino acids is the existence of both a basic and an acidic group at the -carbon. 199-200, pp. 540547, 2012. Additionally, glutamine synthetase activity is most prominent in the presence of high levels of ammonia, and is more limited in the presence of low levels of ammonia [49]. One way of classifying neurotransmitters is whether they are excitatory or inhibitory. Synthetic wastewater was mostly prepared as influent with the addition of ammonium and nitrite in the form of NH4Cl/(NH4)2SO4 and NaNO2. 43, no. Des tudes ont t ralises afin dexpliquer le rle, les bnfices et linnocuit du glutamate monosodique. Acute infusion of the drug LY354740 (also known as eglumegad, an agonist of the metabotropic glutamate receptors 2 and 3) resulted in a marked diminution of yohimbine-induced stress response in bonnet macaques (Macaca radiata); chronic oral administration of LY354740 in those animals led to markedly reduced baseline cortisol levels (approximately 50 percent) in comparison to untreated control subjects. Symptoms indicative of a high level of glutamate include anxiety, depression, restlessness, inability to concentrate, headaches, insomnia, fatigue, and increased sensitivity to pain. Glutamic acid decarboxylase (GAD) is the enzyme that turns glutamate into its calming counterpart, GABA. This indicated that protein might be the key constituent for methanogenic granules and contrarily carbohydrate might be the major constituent for ANAMMOX granules. 4, pp. One human trial found that MSG caused headaches, muscle tightness, numbness, tingling, general weakness, and flushing in some study participants. These results also indicate that inhibition of glutamine synthetase may rapidly impair the retinal response to light. 3949, 2007. M. Ishikawa, T. Yoshitomi, C. F. Zorumski, and Y.

Niftrik, M. Strous, B. Kartal, J. T. Keltjens, and H. J. M. Op Den Camp, Biochemistry and molecular biology of anammox bacteria biochemistry and molecular biology of anammox bacteria M.S.M. S.-Q. The substance was discovered and identified in the year 1866 by the German chemist Karl Heinrich Ritthausen, who treated wheat gluten (for which it was named) with sulfuric acid. [5] Its molecular structure could be idealized as HOOCCH(NH2)(CH2)2COOH, with two carboxyl groups COOH and one amino group NH2. 46434650, 2005. Gluten intolerance, celiac disease, Hashimotos disease, type 1 diabetes, and other autoimmune diseases are linked to GAD autoimmunity. Glutamic acid often is used as a food additive and flavor enhancer in the form of its sodium salt, known as monosodium glutamate (MSG). Energy failure increases vulnerabilities of retinal neurons to excitotoxicity, because the critical steps in glutamate metabolism are ATP-dependent. 19, no. 101, no. Before discovery of granulation mechanism, researchers used single ANAMMOX bacterial cells for reactor operation. ANAMMOX bacteria have been detected in various natural habitats such as anoxic marine sediments and water columns, freshwater sediments and water columns, terrestrial ecosystems, some special ecosystems (e.g., petroleum reservoirs, leachate, pharmaceutical waste, and mangrove), and wastewater treatment systems. L.-D. Shen, A.-H. Hu, R.-C. Jin et al., Enrichment of anammox bacteria from three sludge sources for the startup of monosodium glutamate industrial wastewater treatment system, Journal of Hazardous Materials, vol. H. Li, S. Chen, B.-Z. So, there was a necessity to find out the reason of sludge floatation and control mechanism of floatation for restoration of reactor performance. GLT-1c is normally only expressed by the photoreceptors in the mammalian retina [38]. 100, pp. The change in protonation state occurs at pH 9.47. Glutamic acid (symbol Glu or E; the ionic form is known as glutamate) is an -amino acid that is used by almost all living beings in the biosynthesis of proteins.It is a non-essential nutrient for humans, meaning that the human body can synthesize enough for its use. This is an open access article distributed under the, L. Tremolizzo, M. Milanese, M. J. Seiler, M. Hamann. 3, pp. dans l'huile ou les solvants organiques[2]. Uses of Potassium Hydroxide. 46634666, 1998. 14171420, 2004. Examples are as follows: Both pyruvate and oxaloacetate are key components of cellular metabolism, contributing as substrates or intermediates in fundamental processes such as glycolysis, gluconeogenesis, and the citric acid cycle. 1, pp. Zhang et al. The sizes of interstitial voids were proportional to granular size and voids could serve as water channel and gas tunnel. 5, no. 97, no. 967971, 2009. A. Bringmann, T. Pannicke, B. Biedermann et al., Role of retinal glial cells in neurotransmitter uptake and metabolism, Neurochemistry International, vol. However, the medical establishment still denies the existence of MSG symptom complex and the official stance is that MSG is perfectly safe. It is a dry chemical used in fluoridation of drinking water, it should be manually weighed and added to the mixing tank. Its molecular formula is C5H9NO4. 25012506, 2009. GLT-1 is reported to be down-regulated in glaucomatous eyes in rats [100] and mice [101]. The greatest number of four digits which is exactly divisible by 15 is 9720. (f) ANAMMOX bacteria-like cells (marked with a circle). Glutamate metabolism requires energy supply, and the energy loss inhibits the functions of both glutamate transporters and glutamine synthetase. The international scientific consensus is that MSG is safe. Une tude clinique multicentrique comparative ralise en double aveugle na pas permis de dmontrer la relation entre le complexe de symptme du glutamate monosodique et la consommation de glutamate monosodique chez les individus qui pensaient ragir de faon indsirable au glutamate monosodique. Yang et al. H. Li, S. Zhou, W. Ma, G. Huang, and B. Xu, Fast start-up of ANAMMOX reactor: operational strategy and some characteristics as indicators of reactor performance, Desalination, vol. 40654071, 2013. 143, pp. 10551071, 2009. GLT-1a appears to be associated mainly with a population of amacrine cells, whereas GLT-1b is associated with cone photoreceptors, subpopulations of bipolar cells, and astrocytes [39, 40]. At high removal rate more gas produced inside the sludge which lead to decrease the settleability of sludge, and thus larger sludge became floating and smaller sludge remained settled [89]. A. Novelli, J. Glaucoma is characterized by progressive and accelerated loss of retinal ganglion cells and their axons. Mature ANAMMOX granules settled very well at velocities of 41 to 79m/h, which were similar to the settling velocities of the methanogenic granules (e.g., 52.9m/h) and at least two times greater than those of the flocculated ANAMMOX sludge [41]. While levels in blood, saliva, or urine can be measured, these results have little-to-no correlation with levels in the brain. Its activity at the synaptic cleft is carefully balanced by receptor inactivation and glutamate reuptake. Les fabricants de produits alimentaires commercialisent et utilisent le GMS comme exhausteur de got car il quilibre, mlange et arrondit la perception globale des autres gots[6],[7]. 207219, 2012. Auxigro is a plant growth preparation that contains 30% glutamic acid. Ils sont d'accord sur le fait que l'utilisation du glutamate monosodique ne fait pas beaucoup augmenter les taux d'acide glutamique chez les adultes, cependant ils sont alarms par les effets potentiels chez les enfants[57] et sur les effets potentiels long terme (maladie neurodgnrative) de petites et moyennes variations de niveau d'excitotoxines dans le plasma[58]. In 1945, Grand Rapids, Michigan, changed the water supply fluoride content to 1.0 ppm and thus became the first city to introduce water fluoridation in the world. All of the ANAMMOX granules have gas tunnels and gas pockets. 10, no. 589596, 1998. Symptoms that could be life-threatening and demand immediate medical attention include chest pain, heart palpitations, shortness of breath, and swelling of the throat. The significant findings and crucial development in ANMMOX research have been highlighted in Table 2. ncessaire]. A. Bringmann, T. Pannicke, J. Grosche et al., Mller cells in the healthy and diseased retina, Progress in Retinal and Eye Research, vol. Figures (a) to (d) are in the same magnification. Diabetes caused significant decrease in the transcriptional expression of glutamate transporter SLC1A3 gene encoding GLAST protein, leading to the decreased removal of glutamate from the extracellular space, suggesting that diabetes impairs the glutamate transporter function of Mller cells. S.-Q. Diabetic retinopathy is the most common complication of the diabetes, and a leading cause of visual impairment during the working-age in the industrialized countries [129]. 18, pp. With the increase of Chinese economy the ANMMOX researches tend to move in full-scale treatment plant. The cessation of oxygen and nutrients supply during ischemia increases the susceptibility of the retina for inflammation [70] or the oxidative stress induced by the restoration of blood circulation. It also helps to decrease chest pain associated with coronary heart disease. (a) Pressure-Dependent Glaucomatous Changes with GLAST. Functioning of Heart: Monosodium glutamate is a form of a glutamic acid that helps in improving the functions of the heart beat. T. Rauen, M. Wiener, R. Sullivan, A. Lee, and D. V. Pow, A new GLT1 splice variant: cloning and immunolocalization of GLT1c in the mammalian retina and brain, Neurochemistry International, vol. In this section, I will overview the role of GLAST in the pressure-dependent and the pressure-independent glaucoma models. It was then that the flavouring agent monosodium glutamate (MSG) was prepared from a type of large seaweed. So, it is clear that ANAMMOX bacteria were widely distributed in China and, among them, Brocadia was predominant in fresh water and Scalindua in sea water. As a result, the excessive gas bubbles were entrapped inside gas tunnels. Another way to offset an excess of glutamate is by restoring its balance with GABA. This explains why eating foods that have MSG in them often give a sense of fullness. T. Rauen, W. R. Taylor, K. Kuhlbrodt, and M. Wiessner, High-affinity glutamate transporters in the rat retina: a major role of the glial glutamate transporter GLAST-1 in transmitter clearance, Cell and Tissue Research, vol. Early in the course of diabetic retinopathy, the function of the glutamate transporter in Mller cells is reported to decrease by a mechanism that is likely to involve oxidation [134]. 8, Article ID e44122, 2012. Can eating glutamate-rich foods impact your glutamate neurotransmitters levels? [10] used TBOA alone and in combination with exogenous glutamate to examine the role of glial glutamate transporters in excitotoxic retinal degeneration. Till now, the highest NRR in the world was reported by Chinese research group which was 74.376.7kg-N/m3/d at hydraulic retention time (HRT) of 0.16h [28]. Unlike in the central nervous system [30], it is considered that GLT-1 does not play a predominant role in the physiological glutamate transmission in the retina because antisense GLT-1-knockout mice exhibit almost normal retinal function [24, 30]. H. Lie-Venema, T. B. Hakvoort, F. J. van Hemert, A. F. Moorman, and W. H. Lamers, Regulation of the spatiotemporal pattern of expression of the glutamine synthetase gene, Progress in Nucleic Acid Research and Molecular Biology, vol. These findings indicate that glutamate uptake is not a major role of EAAC1. The red colored is due to high Heme content, grey color due to low content, and back is due to absence of Heme that occurred by blockage of sludge. Glutamate system dysfunction has been linked to numerous psychological and neurodegenerative disorders. " In this section, we describe the abnormalities of glutamate mechanisms in retinal ischemia, glaucoma, and diabetic retinopathy, respectively. 12, pp. This reaction is catalyzed by glutamate decarboxylase (GAD), which is most abundant in the cerebellum and pancreas. After release from the presynaptic neural terminal, glutamate binds to the postsynaptic glutamate receptors, inducing the influx of Na+ and Ca2+, resulting in membrane depolarization. High rate is one of the prime objectives for ANAMMOX process. M. Schmid, U. Twachtmann, M. Klein et al., Molecular evidence for genus level diversity of bacteria capable of catalyzing anaerobic ammonium oxidation, Systematic and Applied Microbiology, vol. Y. Shigeri, K. Shimamoto, Y.

Kanner, Glutamate 404 is involved in the substrate discrimination of GLT-1, a (Na+ + K+)-coupled glutamate transporter from rat brain, Journal of Biological Chemistry, vol. Glutamate transported into the Mller cell is degraded to glutamine by glutamine synthetase. If you are easily stressed out, overwhelmed, and overstimulated, its likely youre producing too little GABA. L. van Niftrik, W. J. C. Geerts, E. G. van Donselaar et al., Combined structural and chemical analysis of the anammoxosome: a membrane-bounded intracytoplasmic compartment in anammox bacteria, Journal of Structural Biology, vol. 369370, 2005. Finally it could be concluded that the changes of Heme content could represent the growth status of ANAMMOX consortia and Heme level could be used to evaluate the relative activity of ANAMMOX microorganisms and to imply the recovery of ANAMMOX reactor performance. When glutamic acid is dissolved in water, the amino group (NH2) may gain a proton (H+), and/or the carboxyl groups may lose protons, depending on the acidity of the medium. Glutamate uptake via GLAST is accompanied by cotransport of three Na+ and one H+, and the counter-transport of one K+ at each glutamate transport. EPSs are distributed throughout the ANAMMOX bacterial surface which attracted scientists to study it with a view of obtaining an efficient, sustainable, and stable sludge granulation for high rate reactor operation. 1, pp. Like cyanamide, it contains 67% nitrogen by mass, and its derivatives have fire retardant properties due to its release of nitrogen gas when burned or charred. Its notoriously difficult to study neurotransmitter levels in the human brain. 4, pp. D. G. Nicholls and M. W. Ward, Mitochondrial membrane potential and neuronal glutamate excitotoxicity: mortality and millivolts, Trends in Neurosciences, vol. 28372843, 2011. 193199, 2012. 3, pp. The high value of specific ANAMMOX activity (up to 5.6kg-N/kg-VSS/d) and short doubling time of bacteria (below 11 days) could be regarded as the key factors to obtain the super high rate performance. C. Hernndez and R. Sim, Neuroprotection in diabetic retinopathy, Current Diabetes Reports, vol. There are two ways glutamate naturally occurs in foods. R. E. Riepe and M. D.

Axonal transport is the prominent energy-consuming process to transport cell organelles, neurotrophic factors, and other substances [119]. 6, pp. 325336, 1996. 68296832, 2006. If you experience problems with mood, sleep, focus, and energy, you may be producing too much glutamate. Most of the research groups had used (NH4)2SO4 and NaNO2 substrates as influent in reactor for N and S source, respectively [15, 37, 38]. S. Wamsley, B. T. Gabelt, D. B. Dahl et al., Vitreous glutamate concentration and axon loss in monkeys with experimental glaucoma, Archives of Ophthalmology, vol. Mais le glutamate monosodique est devenu le point de mire et les symptmes lui ont depuis t associs. The resulting -ketoacid product is often a useful one as well, which can contribute as fuel or as a substrate for further metabolism processes. Y. Tao, D.-W. Gao, Y. Fu, W.-M. Wu, and N.-Q. Tous les sels ont engendr lumami, en plus dun certain got mtallique d aux autres minraux. 12, pp. This implied that pilot-scale reactor operation in China is significant in the transitional point from the development point of view. 513524, 2004. Till now at least 5 genera and 13 species have been identified using culture-independent molecular techniques [12] including Candidatus Brocadia (Ca. These results indicate the important features about the potential risk of energy deprivation in the glaucoma.

ANAMMOX bacteria enumerated, isolated, and identified from different ecosystems in different areas of China have been illustrated in Table 1. 42, no. 1, pp. A key process in amino acid degradation is transamination, in which the amino group of an amino acid is transferred to an -ketoacid, typically catalysed by a transaminase. But its not hard to find lists of reported MSG side effects, even on authoritative websites like Mayo Clinic. [8][9] The change in protonation state is gradual; the two forms are in equal concentrations at pH 2.10.[10]. Compounds such as amino acids that can act as either an acid or a base are called amphoteric. EAAC-1 (EAAT3) is localized in the horizontal cells, ganglion cells, and some amacrine cells. S. S. Hayreh, M. B. Zimmerman, A. Kimura, and A. Sanon, Central retinal artery occlusion. IOP elevation also damaged mitochondria, inducing cellular ATP depletion, resulting in ganglion cell death. U. Imajo, T. Tokutomi, and K. Furukawa, Granulation of Anammox microorganisms in up-flow reactors, Water Science and Technology, vol. 103, no. 546553, 2006. (c) EAAC-1. Slc1a3 and Glul encode GLAST and glutamine synthetase, respectively. 3, pp. Reversal of the glutamate transporter is considered to facilitate the increase of extracellular glutamate concentration to excitotoxic levels.

Gu, More refined diversity of anammox bacteria recovered and distribution in different ecosystems, Applied Microbiology and Biotechnology, vol. 143148, 2004. 200, no. It is hypothesized that glutamate-mediated excitotoxicity may contribute to pathogenesis of glaucoma [88]. [34] reported a complete loss of ANAMMOX activity when the nitrite concentration remained above 5mM (70g N/m3) for a long period (12h). Produits contenant du glutamate monosodique, Lgislation en tant quexhausteur de got, un nombre de preuves consquent issues dun grand nombre dtudes scientifiques, inoffensif pour la population gnrale, aprs plusieurs tudes, des toxicologues ont conclu que le glutamate monosodique est un ingrdient inoffensif pour la plupart des individus, mme lorsquil est absorb en grandes quantits. 283288, 2001. However, Park et al. 401410, 2008. The first full-scale reactor volume was 70m3 which was 7000-fold from 10L lab-scale experiment. Glutamine synthetase is the only enzyme to synthesize glutamine, and plays an important role in glutamate detoxification [45]. Brief description of pilot-scale application of ANAMMOX process in China. 7, no. 97, no. The scanning electron micrographs represented by Tang et al.
