Full textNitrogen is the most limiting essential nutrient for plant growth. Some prokaryotic microorganisms have developed a biochemical mechanism, which allows the reduction of N2, which is abundantly present in the atmosphere, to ammonium that can be assimilated by the plants. Many of these microorganisms form symbiotic associations with other organisms. This is especially true for leguminous plants that form symbiotic associations with bacteria belonging to the Bradyrhizbium, Rhizobium, and Sinorhizobium groups. Bacterial nitrogen fixation from these interactions are extremely important for the global nitrogen balance and plays a major economically role in agriculture. On the other hand, when nitrate is available in the environment, leguminous plants interrupt the symbiotic fixation process to directly use of the nitrate, which is reduced to ammonium by the enzymes nitrate reductase (NR) and nitrite reductase (NiR), and is finally assimilated by the GS/GOGAST system. Although both will result in ammonium as the end-product, in tropical leguminous plants species, mainly those of the Phaseoleae tribe, when ammonium is produced by the symbiotic association the plant translocates mainly ureides via xylem, whereas the plant translocate mainly amides such as asparagine and glutamine, when the ammonium is produced by nitrate reduction. The objective of this study was to identify in Canavalia ensiformes (L.), metabolic alterations dependent upon the concentration of nitrate supplied to the plant. Specific attention was given to the quantity of nitrogen compounds from nitrogen metabolism and asparagine metabolism from the early stage of germination to the reproductive stage, with the identification of the main locations of metabolism for this amide. Amino acids metabolism was significantly altered when nitrate was supplied at different concentrations. Total soluble amino acids, total protein and ureide contents were not dramatically altered when considering the different treatments at the same developmental stage. However, nitrogen metabolism was shown to be drastically altered when different development stages were compared, particularly at the beginning of the reproductive stage, at which time a switch in the location of nitrate reduction, alterations in the total concentration of ureides and amino acids were observed, when compared to the vegetative stage. Nitrate reductase activity of Canavalia ensiformes was shown to be regulated by the concentration of glutamine present in the tissues, exhibiting higher activity in tissues containing lower concentrations of glutamine, which coincided with the shift of the site of nitrate reduction with the changing developmental stage. The understanding of the processes leading to the alterations in the metabolism of nitrate, asparagine, amino acids, and the mechanism related to the synthesis and utilization of amino acids requires further studies.

Full textSimultaneous nitrification and aerobic denitrification (SNaD) is a preferred method for single stage total nitrogen (TN) removal, which was recently proposed to improve wastewater treatment plant design. However, SNaD processes are prone to inhibition by toxicant loading with free cyanide (CN-) possessing the highest inhibitory effect on such processes, rendering these processes ineffective. Despite the best efforts of regulators to limit toxicant disposal into municipal wastewater sewage systems (MWSSs), free cyanide (CN-) still enters MWSSs through various pathways; hence, it has been suggested that CN- resistant or tolerant microorganisms be utilized for processes such as SNaD. To mitigate toxicant loading, organisms in SNaD have been observed to adopt a multiphase growth strategy to sequentially degrade CN- during primary growth and subsequently degrade TN during the secondary growth phase. However, CN- degrading microorganisms are not widely used for SNaD in MWSSs due to the inadequate application of suitable microorganisms (Chromobacterium violaceum, Pseudomonas aeruginosa, Thiobacillus denitrificans, Rhodospirillum palustris, Klebsiella pneumoniae, and Alcaligenes faecalis) commonly used in single-stage SNaD. The use of CN- degrading or resistant microorganisms for SNaD is a cost-effective method compared to the use of other methods of CN- removal prior to TN removal, as they involve multi-stage systems (as currently observed in MWSSs). The use of CN- degrading microorganisms, particularly when used as a consortium, presents a promising and sustainable resolution to mitigate inhibitory effects of CN- in SNaD. However, SNaD is known to be completely inhibited by CN- thus it is imperative to also study some thermodynamic parameters of SNaD under high CN- conditions to see the feasibility of the process. The Gibbs free energy is significant to understand the feasibility of SNaD, it is also vital to study Gibbs free energy to determine whether or not the biological reaction is plausible. The relationship between the rate of nitrification and Gibbs free energy was also investigated. The attained results showed that up to 37.55 mg CN-/L did not have an effect on SNaD. The consortia degraded CN- and achieved SNaD, with degradation efficiency of 92.9 and 97.7% while the degradation rate of 0.0234 and 0.139 mg/L/hr for ammonium-nitrogen (NH4-N) and CN- respectively. Moreover, all the free Gibbs energy was describing the individual processes were found to be negative, with the lowest Gibbs free energy being -756.4 and -1830.9 Kcal/mol for nitritation and nitratation in the first 48 h of the biological, reaction respectively. Additionally, a linear relationship between the rate of NH4-N and nitrite-nitrogen (NO2-N) degradation with their respective Gibbs free energy was observed. Linear model was also used to predict the relationship between NH4-N, NO2-N degradation and Gibbs free energy. These results obtained showed a good correlation between the models and the experimental data with correlation efficiency being 0.94 and 0.93 for nitritation, and nitratation, respectively. From the results found it can be deduced that SNaD is plausible under high cyanide conditions when cyanide degrading or tolerant microorganisms are employed. This can be a sustainable solution to SNaD inhibition by CN- compounds during wastewater treatment. Furthermore, a single strain was purified from the consortium and identified as Acinetobacter courvalinii. This bacterial strain was found to be able to perform sequential CN- degradation, and SNaD; an ability associated with multiphase growth strategy of the microorganism when provided with multiple nitrogenous sources, i.e. CN- and TN. The effect of CN- on nitrification and aerobic denitrification including enzyme expression, activity and protein functionality of Acinetobacter courvalinii was investigated. It was found that CN- concentration of up to 5.8 mg CN-/L did not affect the growth of Acinetobacter courvalinii. In cultures whereby the A. courvalinii isolate was used, degradation rates of CN- and NH4-N were found to be 2.2 mg CN-/L/h and 0.40 mg NH4-N/L/h, respectively. Moreover, the effect of CN- on NH4-N, nitrate-nitrogen (NO3-N) and NO2-N oxidizing enzymes was investigated, with findings indicating CN- did not affect the expression and activity of ammonia monooxygenase (AMO), but affected the activity of nitrate reductase (NaR) and nitrite reductase (NiR). Nevertheless, a slow decrease in NO2-N was observed after the addition of CN- thus confirming the activity of NaR and the activation of the denitrification pathway by the CN-. Moreover, five models’ (Monod, Moser, Rate law, Haldane, and Andrew’s model) ability to predict SNaD under CN- conditions, indicated that only Rate law, Haldane and Andrew’s models, were suited to predict both SNaD and CN- degradation. Due to low degradation rates of NH4-N and CN-, optimization of SNaD was essential. Therefore, response surface methodology was used to optimize the SNaD under CN- conditions. The physiological parameters that were considered for optimization were temperature and pH; with the result showing that the optimum for pH and temperature was 6.5 and 36.5oC respectively, with NH4-N and CN- degradation efficiency of 50 and 80.2%, respectively. Furthermore, the degradation kinetics of NH4-N and CN- were also studied under the optimum conditions in batch culture reactors, and the results showed that up to 70.6% and 97.3% of NH4-N and CN- were simultaneously degraded with degradation rates of 0.66 and 0.41 mg/L/h, respectively. The predictive ability of RSM was further compared with cybernetic models, and cybernetic models were found to better predict SNaD under CN- conditions. These results exhibited a promising solution in the management of inhibition effected of CN- towards SNaD at an industrial scale.

Resumo: Calopogonium mucunoides é uma leguminosa tropical típica de cerrado, sendo muito utilizada em adubação verde e como forrageira. Possui alta capacidade de fixação de nitrogênio, sendo cultivada em solos de baixo pH e pouca fertilidade; e boa resistência à seca, mas não tolera baixas temperaturas. Poucos são os estudos acerca do metabolismo de nitrogênio nesta espécie, mas demonstram que a leguminosa apresenta alta abundância relativa de ureídeos quando fixando nitrogênio. Estudos preliminares nossos demonstraram certa tolerância do mecanismo de fixação à exposição ao nitrato. Este trabalho objetivou estudar o metabolismo de nitrogênio, em Calopogonium mucunoides, identificando as principais alterações no metabolismo de nitrogênio sob diferentes condições de obtenção deste nutriente: plantas cultivadas recebendo solução nutritiva com diferentes fontes de nitrogênio antes da nodulação; e plantas plenamente noduladas, então expostas a receber solução nutritiva com diferentes fontes de nitrogênio, em diferentes concentrações e por diferentes tempos de exposição. Observou-se que a espécie não apresentou nodulação sensível à presença de nitrogênio no meio e, quando plantas plenamente noduladas foram expostas ao nitrogênio, a fixação foi mantida e a atividade da enzima nitrogenase só foi afetada, embora não totalmente, quando as plantas foram expostas a concentrações de 30 mM de nitrato. Por outro lado, a espécie parece responder à fonte de nitrogênio translocando e/ou acumulando diferentes formas de ureídeo (alantoína e ácido alantóico), mas o metabolismo de aminoácidos não apresentou resposta padrão à exposição ao nitrogênio. Estes estudos indicaram tolerância da nodulação e da fixação de nitrogênio desta espécie ao cultivo na presença de nitrogênio, podendo então servir de embasamento a futuros estudos acerca da sensibilidade/tolerância desses processos à presença de nitrogênio no meio em leguminosas em geral
Abstract: Calopogonium mucunoides is a tropical legume found in the ¿cerrado¿ (savanna) regions, and widely used as green manure and forage. It has a high capacity for fixing nitrogen, being cultivated in soils with low pH and poor fertility; and good resistance to drought, but does not tolerate low temperatures. Studies on the nitrogen metabolism of this species are quite scarce but it is known that the legume has a high relative abundance of ureides when fixing nitrogen. Our own preliminary studies suggested certain tolerance of fixation to the presence of nitrate. The objective of the present study was to study nitrogen metabolism in Calopogonium mucunoides, identifying the influence of the nitrogen source on nitrogen metabolism using: different nitrogen sources starting before nodulation; and exposing plants to the same sources only after complete nodulation, at different concentrations and times of exposure. It was found that the nodulation process of this species was not sensitive to the presence of a nitrogen source in the medium and, when fully nodulated plants were exposed to the nitrogen sources, fixation was maintained and the activity of nitrogenase was only affected, albeit partially, when exposed to the highest (30 mM) dose of nitrate. On the other hand, the species appears to respond to the exogenous source of nitrogen by translocating and/or accumulating different forms of ureides (allantoin and allantoic acid), but the metabolism of amino acids did not respond clearly to the nitrogen source. The data indicate that the process of nodulation and nitrogen fixation in this species is tolerant to the presence of a nitrogen source in the medium and should prove useful for future studies on the sensitivity/tolerance of nitrogen fixation to na external nitrogen source in legumes

Full textAmmonium (NH4+) is a nitrogen source of great interest in the context of sustainable agriculture. Its application in the field together with nitrification inhibitors has been extensively proven efficient to limit detrimental N losses compared to the use of nitrate (NO3-). NH4+ is a common intermediate involved in numerous metabolic routes. However, high NH4+ concentrations may lead to a stress situation provoking a set of symptoms collectively known as “ammonium syndrome” mainly characterized by growth retardation. Those symptoms are caused by a combination of, among others, a profound metabolic reprogramming, disruption of photosynthesis, pH deregulation and ion imbalance. Numerous studies have described the way plant copes to ammonium nutrition. However, the organ developmental stage has been generally neglected.To fill in this gap, in the first chapter we first aimed studying how the metabolism is adapted in function of the leaf position in the vertical axis of the tomato plants (Solanum lycopersicum) grown with NH4+, NO3- or NO3NH4 supply. To do so, we dissected leaf biomass composition and metabolism through a complete analysis of metabolites, ions and enzyme activities. The results showed that C and N metabolic adjustment in function of the nitrogen source was more intense in older leaves compared to younger ones. Importantly, we propose a trade-off between NH4+ accumulation and assimilation to preserve young leaves from ammonium stress. Besides, NH4+-fed plants exhibited a rearrangement of carbon skeletons with a higher energy cost respect to plants supplied with NO3-. We explain such reallocation by the action of the biochemical pH-stat, to compensate the differential proton production that depends on the nitrogen form provided.Ammonium nutrition may limit cell expansion, suggesting that the cellular processes involved would be altered. Among others, cell growth is largely dependent of the internal pressure exerted on the cell wall by the vacuole. However, the role of the vacuole in ammonium stress has been rarely addressed. In the second chapter, we evaluated the effect of ammonium stress on leaf development with a special focus on vacuole expansion and metabolism. To carry out this aim, we monitored the leaf development from its appearance until its complete expansion in plants grown under NH4+ or NO3- as unique nitrogen source. Cytological analysis evidenced that the reduced cell expansion under ammonium nutrition was associated with smaller vacuole size. Besides, we reported an acidification of the vacuole of NH4+-fed plants compared to nitrate nutrition. Moreover, a model was built to predict the thermodynamic equilibrium of different soluble species across the tonoplast. The model was set up through an extensive reviewing of vacuolar transporters and integrated subcellular volumes, vacuolar electrochemical gradients and the formation of ionic complex in the vacuole to fit the subcellular concentration of ions, organic acids and sugars measured in the leaf. Further, predictions obtained with the model were cross validated with data from non-aqueous fractionation. Firstly, the entrance of solutes was higher in vacuoles of NO3--fed leaves but was not associated with higher vacuolar osmolarity likely because of the adjustment of the vacuolar volume. In this sense, we proposed that the lack of malate in cells of ammonium-fed leaves was central in the limitation of vacuolar expansion. Secondly, we conclude that the energy cost of solute transport into the vacuole is higher under NH4+ nutrition because of the higher electrochemical gradient generated by the proton pumps across tonoplast.This work highlights the importance of considering leaf phenological state when studying nitrogen metabolism. In addition, our integrated approach place cytosolic pH control and vacuole expansion in the center of tomato leaf adaptation to ammonium stress and pave the way for future studies in the field of ammonium nutrition

Full textPrior studies undertaken in the Laboratory of Plant Physiology on IBUSP with Guzmania monostachia have shown that during water shortage, CAM induction occurs with greater expression in the apical portion of the leaf. In the case of another species (Vriesea gigantean), more intense nitrate reductase (NR) enzyme activity was observed in the basal portion during the daytime. In a certain terrestrial bromeliad (Ananas comosus), signaling by cytokinins, both in the induction of gene expression as well as NR activation, was observed. According to other laboratories, the cytokinins seem to play a negative regulation of phosphoenolpyruvate carboxylase (PEPC) in CAM induced Mesembryanthemum crystallinum plants. As a result of accumulated knowledge, new questions have arisen, such as: Are there daily variations in PEPC and NR enzymes activity in the different portions of CAM induced leaves of G. monostachia? Would the more pronounced nocturnal availability of carbon skeletons (accumulation of acidity) positively influence NR activity, with consequential displacement of its peak of activity to this period? Would variations in endogenous cytokinins concentration accompany possible changes in PEPC and NR activity, thereby indicating the participation of this hormonal class in their regulation? The main aim in the present study was to investigate the possible regulation of PEPC and NR activity by cytokinins in detached CAM-induced leaves of the epiphyte tank bromeliad Guzmania monostachia (Bromeliaceae). The expectations with this research were to study more deeply the inter-relationship between photosynthetic behavior, the capacity for nitrogen assimilation and the possible regulation of PEPC and NR activity by endogenous cytokinins. Analyses of titratable acidity, organic acids, endogenous starch and malate dehydrogenase (MDH) enzyme activity confirmed CAM induction in isolated leaves of G. monostachia kept in polyethylene glycol (PEG) at a concentration of 30%. The use of this compound was efficient in reducing relative water content and imposing leaf water deficiency. Furthermore, compared to the basal portion, greater CAM expression could be observed in the apical portion of leaves kept in PEG 30%. Analyses of PEPC and NR activity allowed detecting their mutual spatial separation, seeing that, in the first greater activity was concentrated in the leaf apex, while in the second this was more pronounced in the basal portion. Even so, no temporal separation could be observed, since peak of activity for both occurred at night. The peak of nocturnal NR activity (1 hour) was observed in control leaves or those undergoing water deficiency, thereby implying that factors, other than CAM metabolism, exerted an influence on the occurrence of more intense activity of this enzyme at this time. Furthermore, there were indications that cytokinins possibly act as a negative regulator of PEPC activity during the daytime, when the highest endogenous levels of this hormone were observed, whereas it was apparent that the most intense activity of this enzyme actually occurred at night, when Z+iP rates decreased significantly. Z or iP application also induced a decrease in the activity of this enzyme. On the other hand, the cytokinins acted as a positive regulator of NR activity, since the nocturnal peak of activity of this enzyme was preceded by 3 or 6 hours by higher endogenous levels of cytokinins in the basal portion of leaves maintained in water or PEG 30%, respectively. The application of free cytokinins induced a significant increase in NR activity in the base of detached leaves kept in water or PEG 30%

Full textThe nitrogen fertilization and its implication in the nitrogen metabolism of coffee plants are not well known in high technology production under field conditions with autumn-winter average temperatures above 22 º C and a larger photoperiod. The objective of this work was to evaluate the nitrate reductase, glutamine synthetase and urease activity due to nitrogen fertilization rates (without N, 200, 400, 600 e 800 kg ha-1). In the present work was evaluated also the influence of nitrogen rates on total nitrogen, nitrate, ammonium, chlorophylls and carotenoids concentration in the leaves, the variation of macro and micronutrients as well as the correlationship between coffee yield and nitrogen fertilization rates. Moreover, the goal of this study was to identify the period of peak activity of nitrate reductase. The experiment was carried out at western of Bahia State and Piracicaba, State of Sao Paulo, Brazil. The periods of evaluations were plant growth, anthesis, pin head fruits, filling and maturation fruits stage development. The highest nitrate reductase activity occurred with 800 kg ha-1 N supply and no changes on this enzyme were observed regarding other rates. Therefore, the nitrogen rates did not affect the glutamine synthetase and urease activity. The nitrate and ammonium concentration did not increase with nitrogen rates; however, the aminoacids concentration increased due to nitrogen fertilization rates. The highest activity of nitrate reductase was observed at 12:00h during plant growth and filling fruits stage development. On the other hand, the higher activity of glutamine synthetase and urease were during filling fruits stage. The highest nitrate concentration was detected during between pin head and beginning of filling fruits stage, and the highest ammonium concentration was during end of filling fruits stage development. The peak activity of nitrate reductase was 25 days after nitrogen fertilization. The high nitrogen rates did not affect the macro and micronutrients concentration in the leaves. The greater coffee yield was provided with 400kg ha-1 of nitrogen supply.
