Journal ArticleDOI
Glutaraldehyde in bio-catalysts design: a useful crosslinker and a versatile tool in enzyme immobilization
Oveimar Barbosa,Claudia Ortiz,Ángel Berenguer-Murcia,Rodrigo Torres,Rafael C. Rodrigues,Roberto Fernandez-Lafuente +5 more
TL;DR: Glutaraldehyde, an apparently old fashioned reactive, remains the most widely used and with broadest application possibilities among the compounds used for the design of biocatalyst.
Journal ArticleDOI
Strategies for the one-step immobilization–purification of enzymes as industrial biocatalysts
Oveimar Barbosa,Claudia Ortiz,Ángel Berenguer-Murcia,Rodrigo Torres,Rafael C. Rodrigues,Roberto Fernandez-Lafuente +5 more
TL;DR: The development of tailor-made heterofunctional supports as a tool to immobilize-stabilize-purify some proteins will be discussed in deep, using low concentration of adsorbent groups and a dense layer of groups able to give an intense multipoint covalent attachment.
Journal ArticleDOI
Importance of the Support Properties for Immobilization or Purification of Enzymes
José C. S. dos Santos,José C. S. dos Santos,Oveimar Barbosa,Claudia Ortiz,Ángel Berenguer-Murcia,Rafael C. Rodrigues,Roberto Fernandez-Lafuente +6 more
TL;DR: This review will focus its attention on the requirements of a support surface to produce the desired objectives, the ideal physical properties of the matrix, the properties ofThe introduced reactive groups, the best surface activation degree to reach the desired objective, and the Properties of the reactive groups will be discussed.
Journal ArticleDOI
Heterofunctional supports in enzyme immobilization: from traditional immobilization protocols to opportunities in tuning enzyme properties.
Oveimar Barbosa,Rodrigo Torres,Claudia Ortiz,Ángel Berenguer-Murcia,Rafael C. Rodrigues,Roberto Fernandez-Lafuente +5 more
TL;DR: This Review will discuss the suitable properties of the groups able to give the covalent attachment, and the groups unable to produce the first enzyme adsorption on the support, as well as the likely pathways for the evolution.
Journal ArticleDOI
Immobilization of lipases on hydrophobic supports: immobilization mechanism, advantages, problems, and solutions.
Rafael C. Rodrigues,Jose J. Virgen-Ortíz,José C. S. dos Santos,Ángel Berenguer-Murcia,Andrés R. Alcántara,Oveimar Barbosa,Claudia Ortiz,Roberto Fernandez-Lafuente +7 more
TL;DR: These immobilized lipases may be subject to unfolding and refolding strategies to reactivate inactivated enzymes, and these biocatalysts have been used in new strategies for enzyme coimmobilization, where the most stable enzyme could be reutilized after desorption of the least stable one after its inactivation.
