Estudo da qualidade da água distribuída pelo poço artesiano da FEG em relação à água servida pelo abastecimento público de Guaratinguetá

We conducted a study of the quality of water distributed by Artesian Well in relation to water supply served by the public for purposes of human consumption of UNESP Campus Guaratinguetá. Two sections of the network were randomly chosen and monitored for 105 days: the stretch of the pipeline started off the Water Treatment Station of the Autonomous Service of Water, Sewage and waste in the Municipality of Guaratinguetá and ended in a point consumption of the Child Family Center, while the section B began at the output of an artesian well and finished in a point of consumption of the Department of Civil Engineering. It is the deterioration of water quality in parts A and B, through comparative analysis of Bicarbonates, Total Hardness, Total Iron, free residual chlorine, pH, Total Residual, Turbidity, Conductivity, Color, Fecal Coliforms and Total Coliforms. Among the observations that can be highlighted: the Total Hardness was found in highest concentration in the extract; for Total Iron significant variations were obtained for both parts, and reduction of this parameter in two points of consumption analyzed, not the expected increase concentration, because the contact of water along the pipe, the CRL showed significant depletion to section A, which can be related to impurities in the water, the presence of biofilm on the walls of pipes, or because this is the stretch of greater extent to be covered by water for pH, this indicated that the water is alkaline and slightly acidic stretch in section B; Turbidity was found for the higher concentration to the passage, and a considerable reduction of this parameter at point consumption due to deposition of particulate matter along the stretch, the conductivity also showed a higher concentration in the extract, as well as an increase in this parameter at the point of consumption.

Micro-fungos de interesse para o setor de petróleo, gás e biocombustíveis

Oil is a hydrocarbon mixture of various sizes, including saturated and aromatic compounds. Natural gas is a mixture of gaseous hydrocarbons and its main component is methane. In our society, the great demand for these fuels requires fast extraction, transportation and refining, increasing the number of accidents that compromise the environment. Oil is a finite resource and it is necessary to reduce the problems related to the question concerning environmental pollution which has encouraged the search for alternative fuel sources in our country. So today we have two major biofuels: ethanol and biodiesel. Concurrently, many studies have been done directed toward the isolation of microorganisms capable of degrading petrochemical industrial wastes, most of them using as a source of isolation soil and water collected in a contaminated environment. Isolation from alternative substrates has emerged as a new strategy that has provided satisfactory results. In this work, we present the leaf-cutter ants of the Attini tribe as a source for the isolation of micro-fungi with the potential for hydrocarbon degradation. These insects have a social way of life and a highly specialized system of intra and interspecific communication, which is based on the recognition of individuals through volatile chemical compounds, the majority hydrocarbons, stored in their exoskeleton. The micro-environment exoskeleton of Attini ants (genus Atta) used in this work proved to be a rich source of microbial biodiversity, as other studies have found. The flotation isolation technique applied here allowed the achievement of 214 micro-fungi, 118 representatives of the dematiaceous fungi group and 96 hyaline filamentous fungi. They were submitted to toluene degradation tests and at least one strain of each genus presented good results, namely Teratosphaeria, Exophiala, Cladosporium, Penicillium, Aspergillus...

Expressão de Pentraxina 3 em membranas corioamnióticas de gestações prétermo complicadas por rotura prematura de membranas pré-termo ou trabalho de parto prematuro

Pentraxina 3 (PTX3) é um componente essencial da resposta imune inata e age como receptores de reconhecimento de padrões (PPRs) reconhecendo produtos microbianos, opsonizando fungos, bactérias Gram positivas e negativas, além de apresentar a capacidade de ativar o sistema complemento. Poucos estudos na literatura mundial têm investigado a expressão de PTX3 nas complicações gestacionais associadas à invasão microbiana da cavidade amniótica e resultados conflitantes têm sido descritos. Avaliar a expressão gênica e protéica de PTX3 em membranas corioamnióticas de gestações pré-termo complicadas por Trabalho de Parto Prematuro (TPP) e bolsa íntegra ou Rotura Prematura de Membranas Pré-Termo (RPM-PT), na presença de corioamnionite histológica (CA). Foram incluídas no estudo 30 gestantes com TPP, sendo 15 na ausência e 15 na presença de corioamnionite histológica e 30 gestantes com RPM-PT, sendo 15 na ausência e 15 na presença de corioamnionite histológica. Cortes parafinizados foram encaminhados à análise histopatológica para confirmação de corioamnionite histológica. Outros fragmentos de 1cm2 das membranas foram submetidos à extração de RNA total. Após a extração do RNA, as amostras com concentração entre 0,02 e 0,2g/ L de RNA foram submetidas à obtenção de cDNA para posterior utilização na quantificação da expressão gênica de PTX3 pela técnica da PCR em tempo real empregando-se o Sistema TaqMan® Gene Expression Assays. Fragmentos das mesmas amostras incluídas no estudo foram utilizados para verificar a expressão da proteína PTX-3 através da técnica de Western Blotting. Dentre as 60 membranas corioamnióticas incluídas no estudo, 56 (93,3%) expressaram PTX-3. Não houve diferença estatisticamente significativa na expressão de mRNA de PTX-3 (p=0,137) entre os grupos: RPM-PT na presença de CA (Md: 0.355; 0.11-1.03), RPM-PT na...(Resumo completo, clicar acesso eletrônico abaixo)

Avaliação do efeito do tratamento com surfactante químico e Pseudomonas aeruginosa LBI na toxicidade de solo contaminado com óleo lubrificante usado

Petroleum and its subproducts are considered a treat for the environmental quality because of the many environmental accidents that may occur during exploitation, transport and storage. A common remediation technique used in the contaminated areas is based on the use of surfactants, mainly the chemical ones, because they have low production costs. In the other hand, some microorganisms have indicate capacities of producing surfactants that emulsify substances and as result, offer a bigger contact surface for the microbiota degradation. This biossurfactants stand out in comparison with the chemical surfactants because they present lower micelar concentration values, are more tolerant for temperature and pH variation, because they are biodegradable, have low toxicity, higher emulsification and hydrocarbon solubilization index. In this way, after the surfactant application, a toxicity evaluation have to be made to identify the treatment effects. In soil, the activity of some microbial enzymes can show the environmental behavior of the contaminant under different treatment conditions. Dehydrogenase is one example of those enzymes that can demonstrate indirectly the effect of the pollutant on the soil microorganisms. The aim of this paper was to evaluate the toxicity after the addition of a surfactant and/or Pseudomonas aeruginosa LBI in soil contaminated by a mineral automotive lubricant. The previous mentioned bacteria are a potential biossurfactant (rhamnolipid) producer. In order to evaluate the toxicity, the dehydrogenase test was run. In this test, trifeniltetrazolium compound (TTC) after utilized as an electron acceptor, turns into trifenil formazan (TPF), that can be indirectly quantified using the absorbance measured by the spectrophotometer UV-visible. In this way, it was possible to quantify the dehydrogenase activity from the contaminated soil samples... (Complete abstract click electronic access below)
