Imobilização da enzima β-galactosidase de Kluyveromyces fragilis em agarose e quitosana utilizando diferentes protocolos de ativação
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2009-02-27)
The objective of this work was stabilize and immobilize β-galactosidase from activated agarose and chitosan supports. Initially, it was evaluated the buffer type, ionic strength and bivalent ions Mn2+ and Mg2+ on the ...
Immobilization and stabilization of an endoxylanase from Bacillus subtilis (XynA) for xylooligosaccharides (XOs) production
(2016-01-01)
Xylooligosaccharides (XOs) are small oligomers constituted by 2-10 units of xylan monomers, with important nutraceutical properties. They can be produced through hydrolysis of xylan catalyzed by an endoxylanase. The use ...
Chemical improvement of chitosan-modified beads for the immobilization of Enterococcus faecium DBFIQ E36 l-arabinose isomerase through multipoint covalent attachment approach
(Springer Heidelberg, 2015-10)
d-tagatose is produced from d-galactose by the enzyme l-arabinose isomerase (L-AI) in a commercially viable bioprocess. An active and stable biocatalyst was obtained by modifying chitosan gel structure through reaction ...
Seleção de suportes e protocolos de imobilização de lipases para a síntese enzimática de biodiesel
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2009-05-25)
The objective of this thesis was to prepare and select immobilized lipase derivatives with high catalytic activity and thermal stability to mediate the biodiesel synthesis from palm and babassu oils by ethanolic route. The ...
Diseño de matrices de quitosano para la inmovilización de beta-galactosidasas y su aplicación en la síntesis de galacto-oligosacáridos
(2015)
The hipothesis of this investigation was: "The chemical modification of the structure of chitosan by the use of different derivatization methologies will allow the development of immobilized β-galactosidase biocatalysts ...
Imobilização e estabilização de D-Hidantoinase para a produção de N-Carbamoil-D-Fenilglicina
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Biotecnologia - PPGBiotec, 2008-09-29)
Immobilization and stabilization of enzymes increases their potential for use in industrial scale. D-hydantoinases (dihidropirimidina amidrohidrolase EC 3.5.2.2) catalyze the hydrolysis of D-hydantoins, generating the ...
Conductive hydrogels based on agarose/alginate/chitosan for neural disorder therapy
(Elsevier, 2019-11)
Electroactive scaffolds derived from carbohydrate hydrogels were synthesized, resulting in a large shift in the conductivity of chitosan (CS) from 10−6 S/cm to about 10-3 S/cm, assigned to CS-oligoaniline. Several analyses ...
