Title: A novel oriented immobilized lipase on magnetic nanoparticles in reverse micelles system and its application in the enrichment of polyunsaturated fatty acids Liu T, Zhao Y, Wang X, Li X, Yan Y Ref: Bioresour Technol, 132C:99, 2013 : PubMed
A novel oriented immobilized lipase was derived from Yarrowia lipolytica lipase LIP2 covalently immobilized on functionalized Fe(3)O(4) magnetic nanoparticles (MNPs) in reverse micelles system (RMS). The activity recovery reached 382% compared with 29% in aqueous phase, and further ran up to 1425% under optimum conditions. (3-Aminopropyl) triethoxysilane (APTES) coated Fe(3)O(4) nanoparticles were characterized by Fourier transform infrared (FT-IR) and X-ray diffraction (XRD). A significant alteration in the secondary structure of the lipase in RMS with a 15.5% increase of alpha-helix content and a 12.5% decrease of beta-sheet content was detected by circular dichroism (CD). The immobilized lipase was employed to enrich polyunsaturated fatty acids in fish oil, a 90% increase of DHA content was obtained after 12h, and after 20 cycles of successive usage, it still remained over 80% of relative hydrolysis degree, which shows a good recyclability.
