Influência de diferentes tratamentos pós-colheita com películas de amido nas características químicas de rosas (Rosa hybrida var. grand galla)

DOAJ (DOAJ: Directory of Open Access Journals) (2010)

Marcelo Vieira Ferraz Marney Pascoli Cereda

Resumo . Este trabalho teve como objetivo avaliar o efeito de peliculas amilaceas de mandioca nas caracteristicas quimicas de hastes de rosas durante a pos-colheita. O experimento foi conduzido no Departamento de Producao Vegetal da UNESP de Botucatu- SP. As hastes florais utilizadas foram da variedade Grand Galla, de cor vermelha, colhidas dois dias antes da instalacao do experimento. Os tratamentos compreenderam a aplicacao filmogenica na haste floral de dois tipos de peliculas (fecula natural 1 e 1,5% e fecula modificada 2 e 3%). Para cada tratamento foram utilizadas 4 repeticoes, cada qual com 6 hastes, perfazendo um total de 120 hastes florais. Apos recobertas por aspersao, estas hastes foram colocadas em vasos de vidro, contendo 250 ml de agua onde permaneceram por 7 dias, sem exposicao direta a luz solar, 60% de umidade, 19°C, luminosidade de 1.500 lux e fotoperiodo de 12 horas. O efeito dos recobrimentos foi avaliado por analise dos teores de acucares redutores, peroxidase, proteina bruta e a atividade respiratoria. Os resultados mostraram que as hastes tratadas nao diferiram da testemunha e que o processo de senescencia ocorreu normalmente, com diminuicao nos teores de acucares redutores e peroxidase.

Democracia e desenvolvimento local em assentamentos rurais Democracy and local development in rural settlements Democracia y desarrollo local en los asentamientos rurales La démocratie et le développement local dans les établissements ruraux

Luiz Fernandes da Costa Luís Carlos Vinhas Ítavo Cláudia Muniz Soares Marney Pascoli Cereda Josemar de Campos Maciel

Abstract : This article refers to the importance of democracy in the processes leading to local development in ruralsettlements. The authors were based on the conceptual core of development in accordance with institutions like theUniversity of Quebec, Canada, pointing to the settlement project Andalucia, state of Mato Grosso do Sul, as apractical example of democracy as a factor to trigger the unfolding local potential. Key-words : Democracy. Local development. Land reform. Resume : Cet article fait reference a l’importance de la democratie dans les processus conduisant au developpementlocal dans les etablissements ruraux. Les auteurs ont ete basees sur Le noyau conceptuel Du developpement emconformite avec des institutions comme l’ Universite Du Quebec, Du Canada, montrant Le projet d’installation surl’Andalousie, l’etat de Mato Grosso do Sul, comme um exemple pratique de la democratie comme um facteur dedeclencher Le deroulement des potentialites locales. Mots-cles : La democratie. Le devepoppement local. La reforme agrarie

CHARACTERISATION OF CASSAVA BAGASSE IN DIFFERENT GRANULOMETRIES FROM TWO STARCH PROCESSING PLANTS

Journal of Microbiology Biotechnology and Food Sciences (2015)

Ãrica Caroline da Silva Marney Pascoli Cereda Tiago André Denck Colman Ivo Mottin Demiate Egon Schnitzler

Cassava is an agricultural crop that occupies an important place in the diet of people of many countries in tropical and sub-tropical regions. Cassava bagasse is a by-product from industrial processing that is generated in great quantities and it can exhibit about 40-50 % of starch in its composition, in dry basis. Two samples, one moist (sample A) and another dry (sample B), were supplied by two cassava starch industries. The samples were analysed by physicochemical, thermoanalytical (TG, DTA, DSC), rheological (RVA) and micro-structural methods (NC-AFM) that demonstrated that the temperature of the industrial drying (around 150 ºC) was not very well controlled, reaching higher temperatures, reaching decomposition of organic matter condition causing changes (please specify) and browning. Although it was milled, sieved and contained 41.31 (0.43) % of starch, sample B did not present gelatinisation or paste properties. Sample A, with 47.75 (0.21) % of starch, dried carefully in a laboratory oven with forced air circulation at 45 ºC for 24 hours showed gelatinisation enthalpy (Hgel) and viscosity with values directly proportional to the granulometry.

Dolomitic limestone as an alkalizing agent for treating cassava starch wastewater in an anaerobic reactor

Revista CERES (2018)

Denise Palma Julia Piechontcoski Fernandes Marney Pascoli Cereda Simone Damasceno Gomes

ABSTRACT Cassava processing wastewater has a low Volatile Acidity/Total Alkalinity ratio, low buffering capacity and became quickly acidified. In this trial, dolomitic limestone was used as an alkalizing agent in an anaerobic reactor to treat cassava starch wastewater. The dolomitic limestone contained 27% CaO and 23% MgO and granulometry between 24.5 and 38.1 mm. The average Chemical Oxygen Demand of the wastewater was 13331.30 mgO2 L-1, the organic loading rates (OLR) ranged from 1.23 to 16.43 gCOD L-1 d-1 and the hydraulic retention times ranged from 10.00 to 0.80 days. The results showed that the calcium concentrations increased in the reactor effluent and the magnesium concentrations decreased as the organic loading rates increased. Ca2+ and Mg2+ concentrations were approximately 5,000 and 5.05 times greater in the sludge than in the inoculum, respectively. The average pH, Total alcalinity, Volatile Acidity and Volatile Acidity/ Total alcalinity values were 6.69, 882.54 mgCaCO3 L-1, 221.55 mgCH3COOH L-1 and 0.22, respectively. The loss of limestone mass corresponded to only 2.51% of the initial mass, after 134 days of anaerobic reactor operation. Finally, it was concluded that the limestone effectively controlled acidification through the alkalinity increased in the system.

Prospecting of culturable acetic acid bacteria from fermented fruits

Journal of Biotechnology and Biodiversity (2013)

Vanessa Cassoni Marney Pascoli Cereda

The flavored vinegars made from wines and fruit are y highlighted in the food gastronomy market. However it is not easy to have a good starter. It is easy to found acetic acid bacteria (AAB) in the natural fermentation of fruits where they are mixed with yeasts. A medium was adapted have only AAB. For test this medium overripe fruits were fermentedby 3 days at room temperature and sampled as inoculum. Bacteria presenting AAB characteristics were identified in microscope. Samples with0.5mlwere placed into Petri dishes containing a modified Frateurmediumcomposed of agar, yeast extract, alcohol, and calcium carbonate. As fungistaticswere tested the gentian violet (1% methylrosanilinium chloride) and nystatin water solution (105 IU) both used at 0.5/1.0/1.5mlon 20mlof the mediumdirectly placed into sterile plates. Petri dishes were incubated at 25°C for five days and AAB colonies recognized by forming a halo. The data showed that only nystatin at dose 1.0 mlcontrolled the wild yeasts growth. Biochemical assays (Gramstaining, oxidase, catalase, indol and H2S formation)confirmed the genus Acetobacter. The data proving that the combination of Frateur medium with 1.0 mlof water solution of nystatin 105 IU)may be a good option for isolating AAB from fermenting fruit.

Controle alternativo de caruncho do bambu (Dinoderus minutus - Fabricius, 1975, Coleóptera: Bostrichidae) à base de extratos vegetais

Cadernos de Agroecologia (2015)

Nathalia Pereira Ribeiro Rudieli da Silva Machado Stéfanny Pereira Navarro Vítor Brito Marney Pascoli Cereda

O objetivo da pesquisa foi avaliar a eficiencia de extratos vegetais de Nim (Azadirachta indica A. Juss) e Barbatimao (Stryphnodendron obovatum Benth) na protecao do bambu contra o ataque do caruncho (Dinoderus minutus). Taliscas de Bambusa vulgaris var.vittata foram imersas nos extratos, sendo comparadas com taliscas tratadas com Bromo nas mesmas condicoes e como controle negativo taliscas ausentes de tratamento. As taliscas foram dispostas em arena acrilica com 100 insetos colocados ao centro, proporcionando as mesmas condicoes de ataque. A diferenca de massa inicial e final das taliscas resultou o ataque dos insetos, mostrando que os tratamentos com extratos vegetais e Bromo nao diferiram significativamente (Bromo 0,36 g, Barbatimao 0,43 g, Nim folha 0,48 g e fruto 0,51 g). Para o controle negativo o consumo apresentou-se maior, sendo de 1,28 g. assim o uso de extratos etanolicos de Nim e Barbatimao tornam-se uma alternativa sustentavel para a conservacao pos-colheita de bambus.
