Immobilization of Lipases onto Magnetic Fe₃O₄ Nanoparticles for Application in Biodiesel Production

Lipase NS81006 immobilized on Fe3O4 magnetic nanoparticles for biodiesel production

“…1 a. These results confirmed the synthesis of Fe3O4, ammonia solution as a precipitator, which could be functionalized on the surface of the magnetic nanoparticles [18]. The broad band at 1106.9 cm -1 and 1321 cm -1 were the contribution of silanol group Si-O, and the adsorption bands at 2917.8 cm -1 (Fig.…”

“…It could be seen that characteristic absorption bands of the Fe-O stretching vibration ascribed at 559.2 cm -1 [14,15], and the contribution of the absorption at 3400 cm -1 was attributed to O-H band [16]. The absorption bands at 1623.1 cm -1 [17,18] and 1396.2 cm -1 [8] revealed that the presence of an amino group (N-H) as shown in Fig. 1 a.…”

Enzyme-Nanoporous Gold Biocomposite: Excellent Biocatalyst with Improved Biocatalytic Performance and Stability

“…The activity of immobilized or free lipase was determined by measuring its initial hydrolysis rate of 4-nitrophenyl palmitate at 40°C according to a previous literature [14]. One unit (U) of lipase activity is defined as the amount of lipase which catalyzes the production of 1 µg p -nitrophenol under the experimental conditions.…”

Metallodendritic Grafted Core–Shell γ‐Fe2O3 Nanoparticles Used as Recoverable Catalysts in Suzuki CC Coupling Reactions

“…It is noteworthy that recent applications and perspectives have dealt with the development of organocatalysis and biocatalysis for the entrapment of enzymes into MNPs. [11] Dendrimer- [12] or dendron-functionalized MNPs have received great attention over the past decade owing to the ability to tune their properties by functionalization. [13][14][15] Each dendron is made of an anchoring site (focal point) and branches that are terminated by catalytic sites.…”
