Composition of bacterial community in enrichment cultures of shale by-products from Irati Formation, Brazil

ABSTRACT We examined microbial communities from enriched fine and retorted shale particles using sequencing of V4 variable region of 16S rRNA. High number of microbial genera was found in both enriched shale by-products that were dominate by Actinobacteria, Firmicutes and Proteobacteria, showing differences due to microbial colonization after the pyrolysis process.

Composition of bacterial community in enrichment cultures of shale by-products from Irati Formation, Brazil.

We examined microbial communities from enriched fine and retorted shale particles using sequencing of V4 variable region of 16S rRNA. High number of microbial genera was found in both enriched shale by-products that were dominate by Actinobacteria, Firmicutes and Proteobacteria, showing differences due to microbial colonization after the pyrolysis process.

Talaromyces sayulitensis, Acidiella bohemica and Penicillium citrinum in Brazilian oil shale by-products.

Fine shale particles and retorted shale are waste products generated during the oil shale retorting process. These by-products are small fragments of mined shale rock, are high in silicon and also contain organic matter, micronutrients, hydrocarbons and other elements. The aims of this study were to isolate and to evaluate fungal diversity present in fine shale particles and retorted shale samples collected at the Schist Industrialization Business Unit (Six)-Petrobras in São Mateus do Sul, State of Paraná, Brazil. Combining morphology and internal transcribed spacer (ITS) sequence, a total of seven fungal genera were identified, including Acidiella, Aspergillus, Cladosporium, Ochroconis, Penicillium, Talaromyces and Trichoderma. Acidiella was the most predominant genus found in the samples of fine shale particles, which are a highly acidic substrate (pH 2.4-3.6), while Talaromyces was the main genus in retorted shale (pH 5.20-6.20). Talaromyces sayulitensis was the species most frequently found in retorted shale, and Acidiella bohemica in fine shale particles. The presence of T. sayulitensis, T. diversus and T. stolli in oil shale is described herein for the first time. In conclusion, we have described for the first time a snapshot of the diversity of filamentous fungi colonizing solid oil shale by-products from the Irati Formation in Brazil.

Consumo de gordura saturada e excesso de peso em trabalhadores de uma indústria de Caxias do Sul, RS / Saturated fat consumption and overweight in workers of an industry of Caxias do Sul, RS

Considerando que o aumento da prevalência de excesso de peso, bem como o surgimento de outras doenças crônicas não transmissíveis, configuram um problema de saúde pública, uma Unidade de Alimentação e Nutrição (UAN) deve buscar adequação das refeições, além de promover educação nutricional. Este estudo foi desenvolvido com os funcionários de uma indústria de Caxias do Sul ­ RS, com objetivo de estimar a prevalência de sobrepeso e obesidade, sua associação com o consumo de gordura saturada proveniente do óleo utilizado para as preparações, na perspectiva de subsidiar estratégias que visam a qualidade da saúde do trabalhador. Através de uma avaliação antropométrica foram obtidas as variáveis de Índice de Massa Corporal (IMC) e Circunferência da Cintura. Também foi analisado o grau de saturação do óleo utilizado na preparação das refeições. O excesso de peso foi observado na maior parte dos trabalhadores (49,3%), já para a obesidade abdominal verificou-se um percentual de 31,3%. A análise do grau de saturação do óleo mostrou valores elevados (5,5%), impróprios para a utilização, contribuindo desta forma para o consumo indireto de gordura saturada e como consequência o sobrepeso nesta população.

Considering that the increasing prevalence of overweight, as well as the appearance of other not transmissible chronic disease, configure a public health problem, a Food and Nutrition Unit (FNU) should seek to appropriate meals, as well as promoting nutrition education. This study was developed with employees of an industry from Caxias do Sul - RS with the objective of estimate the prevalence of overweight and obesity association with the consumption of saturated fat from the oil used for preparations in the perspective of developing strategies aimed at the quality of health worker. Through an anthropometric evaluation variables were obtained from Mass Index (BMI) and waist circumference. Also examined was the degree of saturation of the oil used in the preparation of meals. The excess of weight was observed in most workers (49.3%), while for abdominal obesity there was a percentage of 31.3%. The analysis of the degree of oil saturation showed high values (5.5%), unfit for use, thus contributing to the indirect consumption of saturated fat and overweight as a consequence this population.

Consideracoes sobre a Jornada Academica da Faculdade de Psicologia da PUCRS

O presente artigo tem por objetivo tecer alguns comentarios sobre a realizacao da Jornada Cientifico-Academica da Faculdade de Psicologia e fazer com que algumas discussoes acerca de seus diversos aspectos sejam suscitadas. Pretendendo fazer uma analise destes aspectos, procuramos refletir sobre a funcao, a importancia, o papel e a necessidade da realizacao deste evento e da participacao do corpo docente e discente nele, procurando estender os comentarios a formacao do psicologo como um todo.
