Estudo de ß-glucanas extraídas dos fungos Geastrum saccatum e Polyporos dermoporus: características químicas e atividades biológicas

Fungal polysaccharides have received a great deal of attention due to itsbecause of their potential use in a wide rangegreat variety fromof industries. Some studies have demonstrated that polysaccharides extracted offrom basidiomycetes they have presented significant properties as anti-inflammatory, antimicrobial, antioxidant and anti-tumoral properties. In spite of thisDespite these potential properties, these mushrooms have not been insufficiently investigated, and the great number of antibiotics number produced forby these organisms suggests that they canmay be a new source of bioactives composites source. In tThe present work, reports onlated the chemical composition, potential antioxidant, antiinflammatory and citotoxycity of extracted polymers extracted offrom the fruits bodies of the fungiius Geastrum saccatum and Polyporus dermoporus, native mushrooms of the Atlantic forest inof the state of the Rio Grande do Norte, Brazil. The Cchemical analyses had revealed ademonstrated text of total sugar rates of 65% and 49%, and proteins of 7.0% for in extracts of G. saccatum and P. dermoporus extracts, respectively. The analyses ofNMR spectroscopy of RMN had demonstrated that these extracts are composites forof a complex involving β- glucans and- proteins complex. The inhibition of the formation of superoxide radicals formation was of 88.4% in G. saccatum and 83.3% in P. dermoporus, and 75 and 100% for inhibition of hydroxyls radicals inhibition. TopicalThe topic application of extracts the 10, 30 and 50 mg/kg extract in BALBc mice with cutaneous inflammation induced byfor croton oil demonstrated to inhibitedion of ear edema of ear and cells polimorfonuclears cells atin the inflamed siteplace, being this reply more effective in lower concentrations being more effective. The evaluation of the glucans of G. saccatum and P. dermoporus glucans under induced pleurisy for carrageenan-induced pleurisya of showed the antiinflammatory action of these composites., being analyzed tThe frame number in the pleural exudates and thedosage of nitric oxide dosage was also analyzed. The cytotoxic action of these polymers was analyzed throughthrough the mitochondrial function (MTT). The incubation of the glucans with mononuclear cells of the peripheral blood demonstrated that the extracted glucans extracted fromof G. saccatum havepossess a moderate cytotoxic action. These results suggest that these mushrooms possess polymers formed byfor a complex glucana-protein complex, with antiinflammatory and antioxidant actions

Regulação da mobilização de lipídios e proteinas por hormônios, fontes de carbono e nitrogênio durante o crescimento pos-germinativo em girassol

The mobilization of food reserves in storage tissues and allocation of their hydrolysis products in the growing axis are critical processes for the establishment of seedlings after germination. Therefore, it is crucial for mobilization of reserves to be synchronized with the growing axis, so that photosynthetic activity can be started before depletion of reserves. For this, integrative approaches involving different reserves, different hydrolysis products and interaction between storage and growing axis tissues, either through hormones or metabolites with signaling role, can contribute greatly to the elucidation of the regulation mechanisms for reserve mobilization. In this study, was hypothesized that hormones and metabolites have different actions on reserve mobilization, and there must be a crossed effect of sugars on the mobilization of proteins and amino acids on lipids and starch mobilization in sunflower seedlings. This study was conducted with seeds of sunflower (Helianthus annuus L.) hybrid Helio 253 using in vitro culture system. Seeds were germinated on Germitest® paper and grown on agar-water 4 g/L without addition of nutrients during 9 days after imbibition (DAI) for growth curve. To verify the effect of metabolites and hormones, seedlings were transferred in the 2nd DAI to agar-water 4 g/L supplemented with increasing concentrations of sucrose or L-glutamine, abscisic acid, gibberellic acid or indolebutyric acid. The results of this study confirm that the mobilization of lipids and storage proteins occurs in a coordinated manner during post-germination growth in sunflower, corroborating the hypothesis that the application of external carbon (sucrose) and nitrogen (L-glutamine) sources can delay the mobilization of these reserves in a crossed way. Moreover, considering the changes in the patterns of reserve mobilization and partition of their products in seedlings treated with different growth regulators, it is evident that the effects of metabolites and hormones must involve, at least in part, distinct mechanisms of action

Vicilinas de sementes de leguminosas selvagens:purificação, caracterização, efeito de deletério e mecanismo de ação para bruquídeos e para fungos fitopatogêncios

Globulins fractions of legume seeds of Crotalaria pallida, Erytrina veluntina and Enterolobium contortisiliquum were isolated and submitted to assays against serine, cysteine and aspartic proteinases, as also amylase present in midgut of C. maculatus and Z. subfasciatus. Hemagglutination assays indicated presence of a lectin in E. veluntina globulin fractions. This lectin had affinity to human erythrocytes type A, B and O. Vicilins were purified by chromatography on Sephacryl S-300 followed of a chromatography on Sephacryl S-200, which was calibrated using protein markers. Vicilins from C. pallida (CpV) and E. veluntina (EvV) seeds had a molecular mass of 124.6 kDa and E. contortisiliquum a molecular mass of 151kDa. Eletrophoresis in presence of SDS showed that CpV was constituted by four subunities with apparent molecular mass of 66, 63, 57 and 45 kDa, EvV with three subunities with apparent molecular mass of 45kDa and EcV four subunities, two with 37.1 kDa and two with 25.8 kDa. Non denaturantig eletrophoresis displayed single bands with high homogeneity, where CpV had lower acidic behavior. All vicilins are glycoproteins with carbohydrate contents at 1 to1.5%. Bioassays were done to detect deleterious effects of vicilins against C. maculatus and Z. subfasciatus larvae. CpV, EvV and EcV exhibited a WD50 of 0.28, 0.19 and 1.03%; LD50 0.2, 0.26, and 1.11% respectively to C. maculatus. The dose responses of CpV, EvV and EcV to Z. subfasciatus were: WD50 of 0.12, 0.14, 0.65% and LD50 of 0.09, 0.1, and 0.43% respectively. The mechanism of action of these proteins to bruchids should be based on their properties of bind to chitin present in mid gut of larvae associated with the low digestibility of vicilin. In assays against phytopatogenous fungus, only EcV was capable of inhibit F. solani growth at concentrations of 10 and 20 µg and its action mechanism should be also based in the affinity of EcV to chitin present in the fungi wall

Extração, caracterização estrutural e atividades farmacológicas do olginato obtido da alga marrom Lobophora variegata (Lamouroux) Oliveira Filho, 1977

The alginic acid or alginates are acidic polysaccharides found in brown seaweed widely used in food, cosmetic, medical and pharmaceutical industry. This paper proposes the extraction, chemical characterization and verification of the pharmacological activities of brown seaweed variegata Lobophora . The alginate was extracted from the seaweed Lobophora variegata and part was sulphated for comparative purposes. The native extract showed 42% total sugar, 65% uronic acid, 0,36 % protein and 0% of sulfate, while the sulfate showed 39% , 60%, 0.36% and 27,92 % respectively. The presence of a sulfate group may be observed by the metachromasia with toluidine blue in electrophoresis system and characteristic vibration 1262,34 cm-1 in infrared spectroscopy connections assigned to S = O. We observed the formation of films and beads of native alginate, where more concentrated solution 6% resulted in a thicker and more consistent film. Native alginate showed proliferative activity at concentrations (25 and 50 mcg), (50 mg) and (100 mg) in 3T3 cell line in 24h, 48h and 72h, respectively , as the sulfated (100 mg) in 24 . Also showed antiproliferative or cytotoxic activity in HeLa cells of strain, (25 and 100 mg), (25 and 100 mg) and (25, 50 and 100 mg), to native, now for the sulfate concentrations (100 mg) in 24 (25, 50 and 100 mg) in 48 hours, and (50 and 100 mg ) 72h. For their antioxidant activity, the sulfated alginates have better total antioxidant activity reaching 29 % of the native activity while 7.5 % of activity . For the hydroxyl radical AS showed high inhibition ( between 77-83 % ) in concentrations, but the AN surpassed these numbers in the order of 78-92 % inhibition. The reducing power of AN and AS ranged between 39-82 % . In the method of ferric chelation NA reached 100 % chelating while the AS remained at a plateau oscillating 6.5%. However, in this study , we found alginates with promising pharmacological activities, to use in various industries as an antioxidant / anti-tumor compound

Estudo da adição do resíduo proveniente da extração de minério de ferro em argilas do Rio Grande do Norte

The mining industry is responsible for the generation of waste from their natural process of extraction. The mining impacts in urban areas are of special importance due to the high urban occupation, which are exacerbated due to the proximity of the mined areas and populated areas. Some solutions to wastedisposal have the potential to significantly reduce the environmental risks and liabilities, but represent higher costs in the stages of deployment and operation. The addition of mining waste as raw material in the development of commercial products reduces the environmental impacts, transforming the waste into a positive element in the generation of employment and income. This thesis studies the incorporation of waste iron ore in two clays, one from the ceramic industry of the City of Natal and the other from the ceramic industry of the Seridó Region, both in the State of Rio Grande do Norte, Brazil. Percentages of iron ore waste of 5%, 10% , 15%, 20%, 25% and 30% were used in the tested ceramic matrix. The two clays and the iron ore waste used as part of this investigation were characterized by X-ray diffraction tests, X-ray fluorescence tests, differential thermal analysis, thermogravimetric analysis and dilatometric analysis. The samples were sintered under temperatures of 850 °C, 950 °C and 1050°C at a heating rate of 5 °C/min with isotherms of two hours. The following tests were performed with the samples: linear shrinkage, water absorption, apparent porosity, apparent density, mass loss in fire and bending resistance in order to obtain their physical and mechanical properties. An amount of 5% of waste iron ore in the matrix clay at a temperature of 850 0C resulted in na increase of about 65% in the tensile strength of the clay samples from the Natal ceramic industry. A linear shrinkage of only 0.12% was observed for the samples, which indicates that the physical properties of the final product were not influenced by the addition of the waste

Extração de boro de água produzida sintética por sistema microemulsionado

Boron is a semi-metal present in certain types of soils and natural waters. It is essential to the healthy development of plants and non-toxic to humans, depending on its concentration. It is used in various industries and it s present in water production coming from oil production. More specifically in Rio Grande do Norte, one of the largest oil producers on shore of Brazil, the relationship water/oil in some fields becomes more than 90%. The most common destination of this produced water is disposal in open sea after processing to meet the legal specification. In this context, this research proposes to study the extraction of boron in water produced by microemulsion systems for industrial utilization. It was taken into account the efficiency of extraction of boron related to surfactant (DDA and OCS, both characterized by FT-IR), cosurfactant (butanol and isoamyl alcohol), organic phase (kerosene and heptanes) and aqueous phase (solution of boron 3.6 ppm in alkaline pH). The ratio cosurfactant/ surfactant used was four and the percentage of organic phases for all points of study was set at 5%. It was chosen points with the highest percentage of aqueous phase. Each system was designed for three points of different compositions in relation to the constituents of a pseudoternary diagram. These points were chosen according to studies of phase behavior in pseudoternary diagrams made in previous studies. For this research, points were chosen in the Winsor II region. The excess aqueous solution obtained in these systems was separated and analyzed by ICP OES. For the data set obtained, the better efficiency in the extraction of boron was obtained using the system with DAC, isoamyl alcohol and heptanes, which extracted 49% in a single step. OCS was not viable to the extraction of boron by microemulsion system in the conditions defined in this study

Extração de metais (K, Mg, Ba, Ca, Cr, Mn, Li, Fe) de água produzida utilizando sistema microemulsionado

The produced water is a byproduct formed due to production of petroleum and carries with it a high amount of contaminants such as oil particles in suspension, organic compounds and metals. Thus, these latter pollutants are very difficult to treat because of its high solubility in water. The objective of this work is to use and evaluate a microemulsioned system to remove metals ( K , Mg , Ba , Ca , Cr , Mn , Li , Fe ) of synthetic produced water. For the extraction of metals, it was used a pseudoternary diagram containing the following phases: synthetic produced water as the aqueous phase (AP), hexane as organic phase (OP), and a cosurfactant/surfactant ratio equal to four (C/S = 4) as the third phase, where the OCS (saponified coconut oil) was used as surfactant and n-butanol as cosurfactant. The synthetic produced water was prepared in a bench scale and the region of interest in the diagram for the removal of metals was determined by experimental design called. Ten points located in the phase Winsor II were selected in an area with a large amount of water and small amounts of reagents. The samples were analyzed in atomic absorption spectrometer, and the results were evaluated through a statistical assesment, allowing the efficiency analysis of the effects and their interactions. The results showed percentages of extraction above 90% for the metals manganese, iron, chromium, calcium, barium and magnesium, and around 45% for metals lithium and potassium. The optimal point for the simultaneous removal of metals was calculated using statistical artifact multiple response function (MR). This calculation showed that the point of greatest extraction of metals occurs was the J point, with the composition [72% AP, 9% OP, 19% C/S], obtaining a global extraction percentage about 80%. Considering the aspects analyzed, the microemulsioned system has shown itself to be an effective alternative in the extraction of metals on synthetic produced water remediation

Fungos ectomicorrízicos em áreas de Mata Atlântica do Nordeste do Brasil

Ectomycorrhizal associations are poorly known from tropical lowlands of South America. Recent field trips to the reserve Parque Estadual das Dunas in Natal, in Rio Grande do Norte state, Brazil, revealed a undocumented community of ectomycorrhizal fungi. This type of Mycorrhizal association is frequently in the north hemisphere in temperate and boreal forests. The aim of this work is to analyze the occurrence of ectotrophic areas in atlantic rainforest. Collections along and around the trails in the reserve revealed six genera of putatively ECM fungi which belong to the basidiomycete, Amanitaceae, Boletaceae, Russulaceae, Entolomataceae, and Sclerodermataceae family which are poorly documented in Brazil. Plants belonging to Myrtaceae, Polygonaceae, Leguminosae/Caesalpinioideae, Erythroxylaceae, Malphigiaceae, Bromeliaceae, Loganiaceae, Sapotaceae e Celastraceae were found living next to the species of fungi analized. Our results suggest that the area studied is an ectotrophic environment which shows high diversity of putatively ECM fungi and some plants probably host ECM. The tropical lands are a potential focus to study reinforced by the new records of Scleroderma in Brazil and Northwest of Brazil

Filogenia molecular de fungos gasteroides das ordens Phallales e Geastrales (Phallomycetidae)

Gasteroids fungi are characterized by the basidiospores maturation inside the basidioma, from which spores liberation occurs in a passive manner. These fungi were once seen as a well definite class of Basidiomycota, but nowadays they are considered an artificial assemblage, because the organisms have independent evolutionary histories forming a polyphyletic group with a vast morphological variety. Despite their diversity, studies with this group in the tropics are incipient, and the phylogenetic relationships of the species from temperate climate remain unknown. Thus, this work aimed to elucidate the phylogenetic relationships of gasteroids fungi from the Geastrales and Phallales orders, with the inclusion of tropical and temperate species, and with these analyses suggest a systematic position of species like Aseroë floriformis and Phallus roseus, as well as to verify if the lignicolous habit can indicate parental relationship in the Geastrum genus. For this, basidiomata were collected at Atlantic rain forest areas, during the rainy season, and the specimen identification followed specific literature for gasteroid fungi. The phylogenetic analyses were performed with Maximum Parsimony and Bayesian Analysis, making use of RPB2 and 28S nuclear genes and atp6 mitochondrial gene. It could be observed on the Phallales dendogram, that Aseroë floriformis did not cluster with A. rubra, and that it has an anterior divergence from all others species of the family Clathraceae used in this analysis, assuming a basal position in the clade. Phallus roseus, which once was recognized as Itajahya, has previous divergence from the group formed by Phallus species. At the Geastrales dendogram, in the group corresponding to Geastrum genus, it could be observed that species with lignicolous habitat clustered in a clade with high support values. So, the results suggest the creation of a new genus to accommodate A. floriformis, and the revalidation of Itajahya, as well as it can be affirmed that the lignicolous habitat on the Geastrum genus in fact indicates parental relationships, and that it has arised only once at the evolutionary history of the genus

Incidência de fungos em pós-colheita de banana 'Prata anã'(Musa AAB)

Este trabalho teve por objetivo determinar a ocorrência e a freqüência de fungos em banana 'Prata anã' e elucidar o agente causal das podridões em pós-colheita de frutos provenientes do norte de Minas Gerais. Dois métodos de isolamento foram adotados: diluição em placas, a partir da lavagem de frutos verdes, e direto de frutos maduros. Os fungos Colletotrichum musae, Trichoderma harzianum, Fusarium equisetii, Penicillium sp. Aspergillus parasiticus, Trichothecium roseum, Colletotrichum acutatum, Alternaria sp., Cladosporium musae e Curvularia lunata foram os mais freqüentemente associados aos frutos. A patogenicidade desses fungos foi testada pela substituição de discos da casca de frutos verdes por discos de micélio. Colletotrichum musae apresentou área média lesionada em torno do ponto de inoculação igual a 5,8 cm², enquanto para os demais fungos testados não passou de 1,50 cm². Os resultados mostraram que C. musae é o agente primário das podridões dos frutos examinados com 100 % de incidência e os demais fungos limitaram-se a necrosar os ferimentos em torno do ponto de inoculação. O modo de infecção latente, causada por C. musae, parece favorecer, primeiramente, a colonização interna dos tecidos e, posteriormente, a ação dos fungos oportunistas, que aceleram as podridões nos frutos e na coroa.

Extração e pré-tratamento químico de frutanos de Yacon, Polymnia sonchifolia

O processo de desintegração de tubérculos de yacon promove a incorporação de oxigênio que favorece a oxidação de compostos fenólicos e decorrente contaminação do extrato aquoso com cores e odores objetáveis que prejudicam a sua utilização. Este estudo buscou verificar uma metodologia simplificada de extração dos carboidratos presentes nos tubérculos de yacon e efetuar uma primeira remoção de resíduos e compostos originários das cores e odores indesejáveis, utilizando processos de coagulação e precipitação, aplicando tecnologias de baixo custo. Após a etapa de trituração e remoção dos restos celulares, o extrato teve seu pH aumentado para 9,5 e a temperatura para 90ºC, seguido de sedimentação. A remoção deste precipitado foi realizada por filtração em papel após a coagulação com diferentes concentrações de sulfato de alumínio comercial. Verificou-se que a melhor concentração de coagulante no extrato foi de 100ppm, removendo 90,6% dos compostos coloridos. O balanço de massa mostrou uma recuperação de 47,5% dos sólidos totais sendo que 35,6% estão na forma de carboidratos, verificado através da concentrção de carbono orgânico. O processo de pré-tratamento químico causou hidrólise nos oligofrutanos, detectado por um aumento na concentração de açúcares redutores totais, diretamente proporcional à concentração de sulfato de alumínio utilizado no tratamento de coagulação. Análises cromatográficas indicaram o perfil dos açúcares no hidrolisado e a extensão desta hidrólise que foi considerada pequena. A metodologia aplicada mostrou-se fácil, de baixo custo, eficiente e aplicável em agroindústrias nas zonas produtoras desta espécie de raiz tropical.

Extração, caracterização e atividades biológicas de proteínas da espécie cnidoscolus urens (L.) Arthur

The extraction, chemical and structural characterization of a wide variety of compounds derived from plants has been a major source of bioactive molecules. Several proteases have been isolated in the plant kingdom, with numerous pharmacological and biotechnological applications. Among the proteases isolated from plants, are the fibrinogenolytic, with relevant application in the treatment of disorders in the coagulation cascade, in addition to potential use as a tool in clinical laboratories. In this study, in addition to evaluating the effects of the protein extract of Cnidoscolus urens (L.) Arthur (Euphorbiaceae) in the coagulation cascade also investigates the presence of antimicrobial activity and characterizes the proteolytic activity detected in this extract, aiming to determine their potential pharmacological and biotechnological application. In this way, crude protein extracts obtained from the leaves of C. urens in Tris-HCl 0.05M, NaCl 0.15M, pH 7.5, were precipitated in different concentrations of acetone, and assessed for the presence of proteolytic activity in azocaseína and fibrinogen. The most active fraction (F1.0) in these tests was chosen for assessment of biological activity and biochemical characterization. The Aα chain and Bβ of fibrinogen were completely cleaved at a concentration of 0.18 μg/μL of protein fraction in 4 minutes. Fibrinogenolytic activity presented total inhibition in the presence of E-64 and partial in the presence of EDTA. The fraction demonstrated coagulant activity in plasm and reduced the APTT, demonstrating acting on the factors coagulation of the intrinsic pathway and common, not exerting effects on the PT. Fibrinolytic activity on plasma clot was detected only in SDS-PAGE in high concentrations of fraction, and there were no defibrinating. Although several proteases isolated from plants and venomous animals are classically toxic, the fraction F1.0 of C. urens not expressed hemorrhagic nor hemolytic activities. Fraction F1.0 also showed no antimicrobial activity. In proteolytic activity on the azocasein, the optimal pH was 5.0 and optimum temperature of 60ºC. The enzyme activity has been shown to be sensitive to the presence of salts tested, with inhibition for all compounds. The surfactant triton did not influence the enzyme activity, but the tween-20 and SDS inhibited the activity. In the presence of reducing agents increase in enzyme activity occurred, a typical feature of enzymes belonging to the class of cysteine proteases. Several bands with proteolytic activity were detected in zymogram, in the region of high-molecular-weight, which were inhibited by E-64. In this study, we found that C. urens presents in its constitution cysteine proteases with fibrinogenolytic and procoagulant activity, which may be isolated, with potential application in treatment of bleeding disorders, thrombolytic and clinical laboratory

Diversidade de fungos associados a Parlatoria ziziphus (Lucas)(Hemiptera: Diaspididae) em Citros

As espécies de entomopatógenos que causam impacto em populações de hospedeiros são muitas. Entretanto, informações básicas sobre sua biologia, identificação e relação entre o sistema patógeno-hospedeiro são escassas. Este estudo teve por objetivo identificar os fungos associados a Parlatoria ziziphus (Lucas)em pomares citrícolas do município de Taiúva, SP. Foram realizadas coletas mensais, em dois pomares de laranja (Citrus sinensis Osbeck), variedade Pera, de janeiro de 1995 a fevereiro de 1996. Amostraram-se 15 árvores em cada pomar, retirando-se 16 folhas por árvore. Estas foram levadas ao laboratório, para determinação dos fungos associados à cochonilha. Para a identificação dos fungos, consideraram-se aspectos da estrutura reprodutiva e do esporo. Foram identificadas cinco espécies, citadas como patógenos de diaspidídeos por vários autores: Fusarium coccophilum (Desm.) Wr. & Rg., Nectria flammea (Tul.) Dingley (fase sexual de F. coccophilum), Tetracrium coccicolum Hohnell, Podonectria coccicola (Ellis & Everhart) Petch (fase sexual de T. coccicolum) e Myriangium duriaei Mont. & Berk. Fusarium coccophilum foi a espécie mais freqüente e a mais prevalente, na maioria das coletas realizadas, em ambas as áreas amostradas.
