EFEITO LARVICIDA DE RICINUS COMMUNIS L

Effective larvicides in low concentrations, and is easily obtained in the region, are intensely sought by public health agencies. Therefore, the aim of this study was to evaluate the potential larvicide leaf extract and oil of the fruit of Ricinus communis on the larvae of Aedes aegypti. The results showed that seed and leaf extracts promoted total mortality of the larvae, and this effect is independent of concentration. Therefore, indicates the use of R. communis in endemic regions to control larvae.

CULTIVE TISSUE OF SALVIA HISPANICA L

Chia (Salvia hispanica L.) is an annual herbaceous plant native to Mexico in pre-Columbian times was used a lot with food and medicinal purpose, but during the process of domestication suffered habitat loss due to degradation of natural resources. It has high contente of omega-6 and omega-3, potent antioxidants, protein, dietary fiber, α-linoleic, widely used in weight reduction treatments, and reduction of cholesterol and its price is always high (100 g seed costs on average £ 25.00). The objective was to evaluate the production of seedlings of S. hispanica from embryos in culture media with and without sucrose. Held at 120 seed disinfection detergent Tween 80 for 2 minutes soaking in 1% sodium hypochlorite for 5 minutes in 70% ethanol for 2 min followed by rinsing three times with sterile distilled water. After this procedure, the seeds were placed in glass vials with 5 mL of liquid MS medium plus 30 g L-1 sucrose 100 mg L-inositol 1 pH adjusted to 5.8 without and without phytoregulator agar. Was used as control MS medium without sucrose and without agar. The cultures were kept in a growth chamber at 25 ± 2 ° C under a photoperiod of 16 hours. Each vial contained 30 seeds with 4 replications. We evaluated the germination and early growth of the seedling root and hypocotyl. 60 seedlings per treatment were used for evaluation of measures with a millimeter ruler on the length of the shoot and root. Germination was always higher in cultures with sucrose. Plantlets from 14 days had higher growth of shoots and roots in MS medium with sucrose. Sucrose directly affects seedling development of chia and may impair normal growth and promote somaclonal variation.

PRODUÇÃO DE SABONETES SÓLIDOS COM ÓLEO USADO E ESSÊNCIA DE CRAVO-DA-ÍNDIA

The objective of this study was to promote the reuse of waste oil for the production of solid soap with the essence of as indian clove, putting into practice the sustainability and preservation of the environment, and one of the major factors that contribute to the pollution of the environment is the inadequate disposal of organic waste. Large parts of the population and establishments pour the oil directly in the kitchen sink and put the fat in pet bottle going to the dumps, there is still no ideal disposal, but there are alternative ways to dispose of it, and one of these means is reuse of the oil soaps. The pH measurement was carried out using the technique Adolfo Lutz (1976) in 10g of sample diluted in distilled water. Cooking oil used to manufacture soap had satisfactory results no caustic soda (ph = 7.11).

Bioremediation and remediation with acid residual fluid

The aim of this study was to evaluate the feasibility of using bioremediation and F. moliniforme in remediation of compounds made from plastics and other polymers using waste pollutants. The survival analyzes for survival / growth resistance and pollutants in the concrete for 30 days was observed. We evaluated the size of the colonies in battery fluid (pH = 0.1) and weekly reviews of pH in three 1000 mL volumetric flasks, having in each 133 mL of battery + 100 mg of Fusarium moliniforme. To review the development and formation of colonies of microorganisms miners, we used 320g samples distributed in three trays concrete material. And was inserted solution of green algae free and Fusarium moliniforme life. With mixing the solution with a battery for inoculation of nutrient Fusarium moliniforme in an alkaline environment (pH between 10 and 14) means. Observed the growth of colonies and changing an pHs for a neutral medium (pH 7.0): 78 colonies. In three days sleeve dilution initiated and completed processing within 30 days. This process occurred with a combination of solution and battery residual crushed lime construction and promoted the transformation of the solid phase in the liquid phase in only 30 days. After 2 days s solution was neutralized (pH 7) and thus remaining constant. The battery solution can be neutralized with the addition of carbonates for remediation. The combination of battery solution more carbonates digested the solid state of natural rubber surgical glove can be reused by the industry to produce new products. Fusarium moliniforme biorremediador should be used as the treatment of contaminated soils ex situ, bioadition and bioaugmentation because this fungus neutralized acidic pH of contaminated soils with concrete residue.

EFEITO DA SOLUÇÃO DE HOAGLAND NO TEOR DE AMINOÁCIDOS TOTAIS E NA NODULAÇÃO DE LEUCENA

Plants of Leucaena leucocephala (Lam.) de Wit were evaluated for nodulation and nitrogenous compounds. The plants (n = 18) were grown on substrates of sand, in plastic tubes, in treatments with distilled water (control) and Hoagland solution for a period of five months. Growth evaluations (measures of average height and counted the number of leaves, number of active nodes) and determination of total amino acids were performed. Data were subjected to analysis of variance with 95% probability (Tukey 5%).There was no difference in stem growth and leaf production among treatments. However, the number of nodules was higher in plants treated with distilled water. There was no difference in the content of free amino acids between treatments. We conclude that although the growth in acid soils is lower, this factor does not interfere with the content of amino acids and the formation of nodules.Plants of Leucaena leucocephala (Lam.) de Wit were evaluated for nodulation and nitrogenous compounds.

UTILIZAÇÃO DE FUNGO DE BAMBU NA BIORREMEDIAÇÃO DE SOLO CONTAMINADO

Bioremediation is a technology for treating contaminated sites by the use of biological agents capable of modifying or decomposing pollutants. Whereas all plants can host one or more fungal endophytes, and these have great biotechnological potential the work aimed to study the feasibility of using endophytic fungi from Bambusa vulgaris (Poaceae) in the bioremediation of contaminated soils. For that were made soil contamination ex situ with diesel oil, chorume and the herbicide Roundup and fungus in the dilution of 5 x 105 conidios / mL were evaluated weekly the size of colonies and the fungal growth, the calculation of the initial and final volume of the pollutants tested by Tukey test at 5% probability. The endophytic fungus Fusarium moliniforme Sheld had 99% survival in the three contaminants evaluated within 30 days. The chorume had

Resposta à qualidade de luz como estratégia para estabelecimento de Bidens gardneri

The objective of this study was to investigate the involvement of phytochrome on the germination of achenes of Bidens gardneri Baker., known as black tick. The seeds were separated into short, medium and long sizes. Two experiments used only achenes medium due to differences in the response of germination in the dark, when they were artificially stored in Cerrado soil, in a previous study. The response of achenes short, medium and long to increase flow of white light was observed under a white light gradient from 0 to 46.44 µmol m -2 s -1 creep. The reversal of phytochrome far red (Pfr) in phytochrome red (Pr) in the dark, achenes medium newly collected and stored for 14 months at 4 °C, which were imbibed in water for 24 hours
