Similaridade e fatores determinantes na salinidade das águas superficiais do Ce...
Palácio,Helba A. Q.; Araújo Neto,José R.; Meireles,Ana C. M.; Andrade,Eunice M.; Santos,Julio C. N.; Chaves,Luiz C. G.Técnicas de estatística multivariada foram empregadas com o objetivo de identificar a similaridade dos reservatórios superficiais do Ceará, com relação à salinidade das águas e identificar os fatores determinantes da qualidade das águas. Os dados utilizados foram provenientes do banco de dados da Companhia de Gestão dos Recursos Hídricos do Ceará, no período de 1998/2009, no total de 807 amostras de 48 reservat...
Alternativa potencial para aproveitamento do glicerol gerado na produção de bio...
Freitas,Larissa; Santos,Julio C.; Barcza,Marcos V.; Castro,Heizir F. deEsterification reactions of glycerol with lauric acid in solvent free system were carried out using lipases from several sources. All lipases were immobilized on polysiloxane-polyvinyl alcohol particles by covalent binding with high activity recovered. Among the tested enzymes, the Candida antarctica lipase allowed to attain the highest molar conversion (76%), giving similar proportions of monolaurin, dilaurin ...
Total soluble solids from banana : evaluation and optimization of extraction pa...
Carvalho, Giovani B. M.; Silva, Daniel Pereira da; Santos, Júlio C.; Izário Filho, Hélcio J.; Vicente, A. A.; Teixeira, J. A.Banana, an important component in the diet of the global population, is one of the most consumed fruits in the world. This fruit is also very favorable to industry processes (e.g., fermented beverages) due to its rich content on soluble solids and minerals, with low acidity. The main objective of this work was to evaluate the influence of factors such as banana weight and extraction time during a hot aqueous ex...
Enzymatic synthesis of glyceride esters in solvent-free system: influence of th...
Freitas,Larissa; Perez,Victor H.; Santos,Julio C.; Castro,Heizir F. deThis work assessed the influence of important factors that affect the synthesis of glyceride esters in solvent-free systems, such as: glycerol/fatty acid molar ratio, lipase source and activating agent of the support obtained by the sol-gel technique. Commercial lipase preparations were immobilized on polysiloxane-polyvinyl alcohol particles (POS-PVA) previously activated with different agents (glutaraldehyde, ...
Modificação de óleos e gorduras por biotransformação
Castro,Heizir F. de; Mendes,Adriano A.; Santos,Júlio C. dos; Aguiar,Cláudio L. deThe oleochemical industry has a permanent interested in controlling the physical, functional and organoleptical properties of their products and in producing useful derivatives from their raw materials. The potential of biotechnology for developing novel or well-known products at more competitive costs meets the need of this industrial segment in expanding their goals. In this work some technical aspects, probl...
Estudos de cestóides de peixes do Brasil
Rego,A. Arandas; Santos,Julio C. dos; Silva,Paulo P.Os autores iniciam com este trabalho um estudo sistemático de determinação dos cestóides de peixes depositados na Coleção helmintológica do Instituto Oswaldo Cruz. São referidas ou descritas as seguintes espécies e seus hospedeiros: Schizochoerus liguloideus (Diesing, 1850) e Nesolecithus janicki Posche, 1922, ambas de Arapaima gigas (Cuvier), (piracuru); Gyrocotyle meandrica Herrera, 1946, de Callorhynchus cal...
