Optimization of Biodiesel Production Using Immobilized Candida Rugosa Lipase on Magnetic Fe3O4-Silica Aerogel
Hydrophobic magnetic silica aerogel was used as a support to immobilize Candida rugosa lipase by adsorption method. Physical and chemical properties of the support and immobilized lipase were determined by Field Emission Scanning Electron Microscope (FESEM), Brunauer–Emmett–Teller (BET) analysis and Fourier Transform InfraRed (FT-IR) spectroscopy and the results showed that the lipase was s...
متن کاملUltrasound effects on the activity of free and immobilized urease on the magnetic nanoparticles and silica gel
In this study, the effect of low-frequency ultrasound on the structure and activity of urease enzyme has been investigated. For this purpose, the enzyme was exposed to ultrasound with 20 kHz frequency at different time intervals. The urease enzyme was immobilized on the surface of magnetic nanoparticles (Fe2O3), and activated silica gel with 89% and 66% efficiency respectively. The enzyme activ...
متن کاملImmobilized Lipases on Functionalized Silica Particles as Potential Biocatalysts for the Synthesis of Fructose Oleate in an Organic Solvent/Water System.
Lipases from Thermomyces lanuginosus (TLL) and Pseudomonas fluorescens (PFL) wereimmobilized on functionalized silica particles aiming their use in the synthesis of fructose oleate in a tert-butyl alcohol/water system. Silica particles were chemically modified with octyl (OS), octyl plus glutaraldehyde (OSGlu), octyl plus glyoxyl(OSGlx), and octyl plus epoxy groups(OSEpx). PFL was hyperactivate...
متن کاملThe effect of smart water and silica nanoparticles injection on wettability of limestone
Today, by using half of the oil reserves of the world, natural production of oil has decreased drastically. Gas and water injection for maintaining reservoir pressure is not responsive for oil production.At first, we dispersed silica nanoparticles in low salinity and after two weeks, there was no change in its stability. Then we mixed the nanoparticles in low salinity. After a while, we found o...
