1. [PROVISIONAL] Boundaries in metagenomic screenings using lacZα-based vectors
Article Metagenomics approaches have been of high relevance for providing enzymes used in diverse industrial applications. In the current study, we have focused on the prospection of protease and glycosyl hydrolase activities from a soil sample by using the lacZα -based plasmid pSEVA232. For this, we used a functional screen based on skimmed milk agar and a

2. Decomposição de resíduos da colheita e transferência de carbono para o solo em plantações de eucalipto / Harvest residue decomposition and carbon transference to the soil in eucalypt plantations
In Brazil, eucalyptus is planted in regions with different climate and soil conditions, which affect harvest residue decomposition and the rate of carbon transference fromresidues (Cres) to the soil, hence influencing soil organic matter (SOM) content. SOM is considered one of the most important indicators of soil quality and forest production sustainability

3. ESTUDO COMPARATIVO ENTRE EXTRAÇÃO SOXHLET E ULTRASOM PARA DETERMINAÇÃO DE HIDROCARBONETOS POLICÍCLICOS AROMÁTICOS EM SEDIMENTOS DO ESTUÁRIO DO RIO SERGIPE POR CROMATOGRAFIA A GÁS ACOPLADA A ESPECTROMETRIA DE MASSAS. / COMPARATIVE STUDY OF EXTRACTION SOXHLET AND ULTRASOUND DETERMINATION FOR OIL POLYCYCLIC AROMATIC SEDIMENTS SERGIPE RIVER ESTUARY BY GAS CHROMATOGRAPHY MASS SPECTROMETRY ATTACHED.
Polycyclic aromatic hydrocarbons (PAHs) are compounds that can be found in environmental compartments such as atmosphere, soil, sediment and water. Throughout bioaccumulation, they can also be incorporated into vegetables and animals tissues. They are mainly originated from anthropogenic sources such as fossil fuels and biomass burnings. Due they potential t

4. Contribuicao de fungos micorrizicos arbusculares nativos no estabelecimento de aristida setifolia Kunth em areas degradadas do cerrado.
Para estudar a dinamica de fungos micorrizicos arbusculares (MA) nativos, em solo de cerrado natural e de tres areas degradadas, foram efetuadas avaliacoes quantitativa e qualitativa desses fungos, nos periodos seco e chuvoso. Nessa avaliacao incluiram-se parcelas experimentais, em uma das areas degradadas, com calcario, turfa natural e torta de mamona. Em c

5. Superfosfato triplo, lama vermelha e zeólitas para remediação de metais pesados em solo contaminado / Remediation of contaminated soil with heavy metal using triple superphosphate, red mud and zeolites
Due to the heavy metal persistence in soils, the contamination by these elements is considered permanent and might result in great impact causing a degradation of the chemical and biological properties of the soil. Stabilization techniques have been used as an efficient tool for the remediation of soils that are contaminated by heavy metals, and they show al

6. Influence of land usage changes in soil properties in an ecosystem of the Amazon south occidental. / Influência da mudança no uso do solo nas propriedades edáficas em ecossistema da Amazônia Sul Ocidental.
The inadequate land management causes soil degradation, which, if reversible, will require time and resources for recovering. Evaluations of changes in soil properties using soil quality indicators contribute to avoid soils more susceptible to decrease their natural productive capacity. The aim of this study was to verify the influence of changes in land usa

9. Application of vermicomposting for the biorremediation of contaminated soil by polycyclic aromatic hidrocarbons / Aplicação de vermicompostagem para a biorremediação de solos contaminados por hidrocarbonetos policíclicos aromáticos
One of the main environmental problems that we face today is the soil contamination due to storage fuel tanks leakages. Fuels are comprised of a variety of hydrocarbons, among them are the polycyclic aromatic hydrocarbons (PAHs). Those are classified by US-EPA and NIOSH as prioritary contaminants, due to their carcinogenic and mutagenic characteristics and t

10. Padronização de ténica para recuperação de ovos de Toxocara canis em solo / Padronization of technique for recovery of Toxocara canis in soil
The purpose of this study was to standardize a flotation technique for the recovery of Toxocara canis eggs from soil, comparing different steps. The tests were done under standardized conditions on 1 g of previously sterilized soil samples contaminated experimentally with 200 eggs of T. canis. The following variables were evaluated in serial steps: sieving;

11. Adubação nitrogenada com uréia e adubos verdes na cultura do arroz e efeito residual no feijoeiro / Nitrogen fertilization with urea and green manures in rice crops and its residual effect in bean crop
The association of green manures and mineral N sources is becoming a promising option for nitrogen fertilizer management, with the objective of recovering the soil fertility, increase of soil organic matter, reduce the loss of mineral N from the readily available sources, and in the case of legume incorporate biologically fixed N to the soil. The objectives

12. Efeito de plantas de cobertura sobre os atributos físicos de um solo construído na área de mineração de carvão de Candiota-RS após três anos / Effect of cover crops on the physical attributes of constructed soil in coal mining area in Candiota-RS, Brazil, after three years
O carvão mineral apresenta importância estratégica na expansão do sistema elétrico nacional. A jazida de Candiota no RS é a maior do Brasil, com 38% de todo carvão nacional extraído a céu aberto. Este tipo de extração, aliado ao trânsito de máquinas pesadas, causa alterações negativas ligadas a estrutura do solo. Logo, atributos como a densida
