25. Variantes de inibidores de [alfa]-amilases selecionados por Phage Display com atividade para [alfa]-amilases do bicudo do algodoeiro (Anthonomus grandis, coleptera: curculionidae)
The cotton boll weevil Anthonomus grandis is an important insect-pest, that causes severe damage in cotton floral fruits and buds. The A. gradis larvae development control is a difficult job because it occurs inside the cotton floral structures. Starch granules from cotton structure are digested by a-amylases secreted to the intestinal lumen. However, a-amyl

26. Produção de amilase por Bacillus licheniformis utilizando meios de baixo custo
A indústria biotecnológica enzimática vem aumentando progressivamente nas últimas décadas com a utilização e produção de diversas enzimas microbianas. As amilases são enzimas que hidrolisam moléculas de amido liberando diversos produtos secundários, incluindo as dextrinas e progressivamente por unidades de glicose. Apresentam um amplo campo de ap

27. Estudo da produção de enzimas amiloliticas pelo fungo Metarhizium. / Study of the amylolytic enzymes production by Metarhizium anisopilae using chaff and rice bran as substrates.
The fungus Metharhizium anisopliae has been used as biocontrol agent, actuating on insects in different areas of Brazil, with main application in sugarcane farmings. Such a biocontrol process involves the adhesion of the fungus spores to the surface of the insect, destruction of the same through the mechanical pressure of the hyphal, as well the processes of

28. Características fenotípicas de Enterobacter cloacae controladas pelo sistema quorum sensing / Phenotypics characteristics by Enterobacter cloacae controlled for the system quorum sensing
Many bacteria present an elaborate system of communication dependent of cell density known as quorum sensing, and the knowledge of the phenotypes controlled by this mechanism may contribute for the elucidation of important processes in food microbiology. The objective of this study was to determine phenotypes regulated by quorum sensing in Enterobacter cloac

29. Atividade da amilase e ácido úrico salivar em pacientes submetidos à nutrição enteral exclusiva.
A saliva é o produto da secreção das glândulas salivares, representadas principalmente pelas parótidas, submandibulares e as sublinguais, além de inúmeras outras pequenas glândulas bucais. O fluxo salivar normal exerce um papel vital na manutenção da saúde da orofaringe. Em pessoas com distúrbios da deglutição, a aspiração do conteúdo orofar

30. Characterization and recovery of alfa and beta amylases enzymes by expanded bed adsorption systems / Caracterização e recuperação das enzimas alfa e beta - amilases em sistema de adsorção em leito expandido
Aiming to development of new technologies, in this work a and b-amylases recovery from maize (Zea mays) malt by expanded bed adsorption (EBA) was studied in order, to aggregate value to the maize culture which is diffused into our Country. Thus, the optimization of the manufacture steps of maize malt, since the germination (changing the time) until the dryin

31. Alfa e beta-amilase no metabolismo do amido durante o amadurecimento da banana: clonagem, expressão e caracterização molecular / Alpha and beta-amylase in the starch metabolism during banana ripening: cloning, expression and molecular characterization.
The starch breakdown in plants is accomplished by several enzymes and pathways and it is the main feature of the ripening in climacteric fruits, such as banana. The function of the hydrolytic enzymes, alpha-amylase and beta-amylase, in the starch-to-sugar metabolism during banana ripening, was evaluated through the determination of the profiles of transcript

32. Análise sialométrica e das concentrações salivares de cálcio, amilase, uréia e proteínas totais de indivíduos portadores da anemia de Fanconi
Fanconi anemia (AF) is a genetic disease characterized by a chromosomal instability that develops an intense and progressive pancitopenia, leukemia and/or solid tumors. Nevertheless, it is unknown if this illness induces changes on the salivary gland parenchyma and composition of its secretion. The aim of this study was to assess the stimulated whole saliva

33. Production, partial purification, caracterization and application of thermo-stable alpha-amylase produced by bacterium. / Produção, purificação parcial, caracterização e aplicações de alfa-amilase termoestavel produzida por bacterias.
Os produtos da hidrólise do amido são, certamente, os ingredientes mais versáteis utilizados nas indústrias de alimentos, reconhecidos tanto pelas suas características tecnológicas e nutricionais quanto pela variedade de produtos deles obtidos. Dentre estes produtos, encontram-se os xaropes de açúcares e seus derivados, empregados tanto em processos

34. Screening for carbohydrate-binding proteins in extracts of Uruguayan plants
The presence of carbohydrate-binding proteins, namely lectins, ß-galactosidases and amylases, was determined in aqueous extracts of plants collected in Uruguay. Twenty-six extracts were prepared from 15 Uruguayan plants belonging to 12 Phanerogam families. Among them, 18 extracts caused hemagglutination (HAG) that was inhibited by mono- and disaccharides in

35. Recuperação das enzimas Alfa e Beta - amilases em sistema bifasico aquoso PEG / CACL2 para uso como biocatalisador de amilaceos
Aqueous two-phase systems (A TPS) PEG/ CaCl2 was studying in pH 5,0; 6,0 and 7,0 and polymer molecular weight 4000, 6000 and 8000, in environment pressure and temperature. The enzymes ? and ?-amylases from maize malt was recovered in bath and continuous extraction process, it was valorized this product. The enzymes were obtained by germination of maize seeds

36. Avaliação das alterações histopatologicas do pancreas de camundongos infectados experimentalmente pela cepa RAL de Trypanosoma cruzi
Searching the physiopatology of Chagas disease in clinical researches, the idea that the bearers of this disease present what could be defined as a difficulty of the sick organism in maintaining the homeostasis through the regulation of their functions as motive, secretors or metabolic. One of the main causes related to the diversity of anatomopathological a
