Nanobioconjugates of Candida antarctica lipase B and single-walled carbon nanotubes in biodiesel production

Abstract

Carboxylated single-walled carbon nanotubes (SWCNTCOOH) were used as support for covalent immobilization of Candida antarctica lipase B (CaL-B) using linkers with different lengths. The obtained nanostructured biocatalysts with low diffusional limitation were tested in batch mode in the ethanolysis of the sunflower oil. SWCNTCOOH-CaL-B proved to be a highly efficient and stable biocatalyst in acetonitrile (83.4% conversion after 4h at 35°C, retaining >90% of original activity after 10 cycles).

Keywords: Biodiesel production; Covalent immobilization; Lipase B from Candida antarctica; Single-walled carbon nanotubes.
