Magnetic lipase B from Candida antarctica (CALB) biocatalyst for integrated valorization of tilapia by‐products and biodiesel biorefining

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract The immobilization of lipase B from Candida antarctica (CALB) on an amino‐epoxy functionalized magnetic support (Fe3O4‐PEI‐DGEBA) resulted in a highly stable and efficient biocatalyst for biofuel production from tilapia oil. The synthesized support was characterized using scanning electron microscopy, transmission electron microscopy, X‐ray ...

Stabilization and encapsulation of magnetite nanoparticles

open access: yesMaterials Research Express, 2016
The goal is to stabilize magnetite nanoparticles (NPs) in order to prepare them for encapsulation and to obtain a core–shell structure. Magnetite NPs were obtained by a co-precipitation method and then treated with different stabilizing agents in order to get a full dispersion in an aqueous medium.
