Abstract

Highlights: A new biocatalyst for biodiesel production by immobilization of CaL-B on C-nanotubes. A strong influence of the linker length on enzyme activity was observed. The biocatalyst was determined through several optimization rounds. Recycling studies showed that the new biocatalyst has high operational stability. 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 4 h at 35 °C, retaining >90% of original activity after 10 cycles).
