Screening and Bioprospecting of Anaerobic Consortia for Biofuel Production Enhancement from Sugarcane Bagasse.

The genera Dysgonomonas, Coprococcus, Sporomusa, Bacteroides, Sedimentibacter, Pseudomonas, Ruminococcus, and Clostridium predominate in compost residue, and vadimCA02, Anaerobaculum, Tatlockia, Caloramator, and Syntrophus prevail in soil used as inoculum in batch rectors. This mixed consortium was used as inoculum for biogas production using different concentrations of sugarcane bagasse (SCB) (from 1.58 to 4.42 g/L) and yeast extract (YE) (from 0.58 to 3.42 g/L) according to a composite central design. The maximum ethanol production (20.11 mg L-1) was observed using 2.0 and 3.0 g L-1 of YE and SCB, respectively (C6). Likewise, the highest hydrogen production (0.60 mmol L-1) was observed using 3.0 and 4.0 g L-1 of YE and SCB, respectively (C1). Methane was also observed, reaching the maximum production (1.44 mmol L-1) using 1.0 and 4.0 g L-1 of YE and SCB, respectively (C2). The archaeal similarity between these conditions was above 90%; however, the richness and diversity were higher in the C2 (12 and 2.42, respectively) than in C1 (5 and 1.43, respectively) and C6 (11 and 2.29, respectively). Equally, the bacterial similarity between C1 and C6 was 60% while richness of 24 and 17 and diversity of 3.13 and 2.81 were observed in C1 and C6, respectively.

Diagnóstico sócio-sanitário do Município de Esmeralda - RS / A social-sanitary diagnosis of the municipality of Esmeralda - RS

Este trabalho propoz-se a levantar todos os dados gerais disponíveis sobre o Município de Esmeralda que possam embasar um diagnóstico sócio sanitário, o qual poderá subsidiar um Plano Municipal de Saúde.

Amostra para controle de qualidade do eritrograma estavel durante 100 dias / Sample for quality control of red blood cells measurements with stability for up to 100 days

Eritrocitos de sangue humano de doadores saudaveis foram suspensos em meio CE de preservaçao, incubados durante 1 hora em glutaraldeidoa 0,5g/l, sob constante homogeneizaçao, e ressuspensos em meio CE contendo vitamina E (concentraçao final de 21 mg/l). Os resultados obtidos indicam que o tratamento e conservaçao de eritrocitos nas condiçoes especificadas podem levar a obtençao de amostras adequadas ao controle de qualidade do eritrograma, validas durante aproximadamente tres meses.
