Scenedesmus obliquus as feedstock for biohydrogen production by Enterobacter ae...
Batista, Ana Paula; Moura, Patrícia; Marques, Paula Alexandra; Ortigueira, J.; Alves, Luís Manuel; Gouveia, L.Hydrogen (H2) gas is seen as an ideal future energy carrier because it is easily converted into electricity in fuel cells, liberates a large amount of energy per unit mass, and generates no air pollutants. In this work, biological hydrogen (bioH2) was produced from the microalgal biomass of Scenedesmus obliquus which was used as a substrate for the fermentation by Enterobacter aerogenes ATCC 13048 and Clostridi...
Perceção dos profissionais de saúde face à adesão dos utentes aos programas de ...
Batista, Ana Rita AlmeidaIntrodução – A adesão aos programas de reabilitação constitui uma fonte de preocupação transversal a todos os profissionais de saúde. Com o evoluir dos tempos o utente deixou de ter um papel passivo relativamente às prescrições médicas e passou a ter uma responsabilização individual pelo seu estado de saúde e controlo da sua doença. Porém, a taxa de incumprimentos continua ainda particularmente elevada.Nestaper...
Compara????o das vers??es completa e reduzida da Escala de Compet??ncia de Estu...
Almeida, Leandro S.; Joly, Maria Cristina Rodrigues Azevedo; Fernandes, Dario; Dias, Anelise Silva; Oliveira, Sandra; Bustamante, Maria; Batista, AnaEste estudo objetivou comparar as duas vers??es da Escala de Compet??ncia de Estudo -ECE(C&T), uma a original com 54 itens e outra reduzida com 19 itens, por meio da Teoria de Resposta ao Item (modelo Rasch). Participaram 129 universit??rios de ambos os sexos, com idades variando de 17 a 48 anos (M = 24.65, DP = 6.54). Os coeficientes de precis??o obtidos foram de .91 para escala com 54 itens e de .90 para a d...
Insights on the safety of carotenogenic Chlorella vulgaris in rodents
Sampayo, C.; Corvo, M. L.; Mendes, Rogério; Duarte, D.; Lucas, Joana; Pinto, R.; Batista, Ana Paula; Raymundo, Anabela; Lima, B. SilvaChlorella vulgaris (Cv) biomass is widely used as a traditional food in the Orient and its safety for human consumption has been proved. However, carotenogenic biomass (orange), resulting from induced stresses, needs further safety evaluation, which is the aim of this study. The preliminary toxicological characterization of Cv consisted of a single dose (mice), repeated dose studies (mice and rats) and a biodis...
Isochrysis galbana and Diacronema vlkianum biomass incorporation in pasta produ...
Fradique, Mónica; Batista, Ana Paula; Nunes, Cristiana M.; Gouveia, L.; Bandarra, Narcisa M.; Raymundo, AnabelaFactors such as an ageing population, increased health care costs and rapid advances in science and technology are likely driving the increase interest among consumers in attaining wellness through diet, which is in turn, fuelling interest in functional foods and changing the way that people eat. Microalgae have been largely cultured and commercialized as food and feed additives, their potential as source of hi...
A biorefinery from Nannochloropsis sp. microalga – Extraction of oils and pigme...
Nobre, Beatriz P.; Villalobos, Fidel; Barragan, Blanca E; Oliveira, A. C.; Batista, Ana Paula; Marques, Paula Alexandra; Mendes, Rui L.; Sovová, H.The microalga Nannochloropsis sp. was used in this study, in a biorefinery context, as biomass feedstock for the production of fatty acids for biodiesel, biohydrogen and high added-value compounds. The microalgal biomass, which has a high lipid and pigment content (mainly carotenoids), was submitted to supercritical CO2 extraction. The temperature, pressure and solvent flow-rate were evaluated to check their ef...
Comparison of microalgal biomass profiles as novel functional ingredient for fo...
Batista, Ana Paula; Gouveia, L.; Bandarra, Narcisa M.; Franco, J. M.; Raymundo, AnabelaMicroalgae are one of the most promising sources for new food and functional food products, and can be used to enhance the nutritional value of foods, due to their well-balanced chemical composition. Knowing their physicochemical characteristics is fundamental for the selection of the most suitable microalgae to specific food technology applications and consequently successful novel foods development. The aim o...
A biorefinery from Nannochloropsis sp. microalga – Energy and CO2 emission and ...
Ferreira, Ana F.; Ribeiro, Lauro A.; Batista, Ana Paula; Marques, Paula Alexandra; Nobre, Beatriz P.; Palavra, António F.; Silva, Patricia P. daAre microalgae a potential energy source for biofuel production? This paper presents the laboratory results from a Nannochloropsis sp. microalga biorefinery for the production of oil, high-value pigments, and biohydrogen (bioH2). The energy consumption and CO2 emissions involved in the whole process (microalgae cultivation, harvest, dewater, mill, extraction and leftover biomass fermentation) were evaluated. An...
Estudo tipológico e conceptual de uma creche e jardim de infância para o Bairro...
Batista, Ana Margarida Carreiro LimaEsta Tese tem como objectivo, contribuir para a construção de uma Creche e Jardim de Infância num bairro social de modo a minimizar a realidade actual, bem como a problemática nos "Bairros Sociais". Este estudo incidiu sobre o Bairro da Cova da Moura, situado no concelho da Amadora, sendo considerado um dos mais perigosos da cidade de Lisboa. O Trabalho iniciou-se com uma análise á origem do Bairro da Cova da M...
Biological hydrogen production by Anabaena sp. – Yield, energy and CO2 analysis...
Ferreira, Ana F.; Marques, Ana C.; Batista, Ana Paula; Marques, Paula Alexandra; Gouveia, L.; Silva, Carla M.This paper presents laboratory results of biological production of hydrogen by photoautrotophic cyanobacterium Anabaena sp. Additional hydrogen production from residual Cyanobacteria fermentation was achieved by Enterobacter aerogenes bacteria. The authors evaluated the yield of H2 production, the energy consumption and CO2 emissions and the technological bottlenecks and possible improvements of the whole energ...
