Easily handling penicillin G acylase magnetic cross-linked enzymes aggregates: Catalytic and morphological studies
(Elsevier B.V., 2014-01-01)
Biomolecules labeled with superparamagnetic nanoparticles can be selectively removed from complex reaction mixtures using an external magnetic field. Amino-functionalized superparamagnetic iron oxide nanoparticles (amino-SPION) ...
Synthesis and characterization of magnetic cross-linked enzyme aggregate and its evaluation of the alternating magnetic field (AMF) effects in the catalytic activity
(2020-12-15)
A magnetic cross-linked enzyme aggregate (MCLEA) of cellulases and a non-magnetic analogue (CLEA) were synthesized and further investigated. The obtained MCLEA and CLEA showed a high enzyme loading efficiency of 90% and ...
Compósitos reticulados de Eversa® Transform e nanopartículas magnéticas como biocatalisadores para a síntese de biodiesel em reator de fluxo em vórtices
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2020-10-30)
The enzymatic production of biodiesel is a promising alternative to the conventional production
by the alkaline route in a homogeneous medium. The enzymatic process allows using raw
material with any concentration of ...
Improved development in magnetic Xyl-CLEAs technology for biotransformation of agro-industrial by-products through the use of a novel macromolecular cross-linker
(Elsevier Science, 2020-09)
Cross-Linked Enzyme Aggregates (CLEAs) technologies for enzyme immobilization are influenced by mass transference problems as the degree of molecular crosslinking achieved strongly affects the enzyme exposure to the ...
Estratégias para a síntese de agregados reticulados porosos de lipase de pâncreas de porco com propriedades magnéticas
