Citronellyl Butyrate Synthesis in Non-Conventional Media Using Packed-Bed Immobilized Candida Rugosa Lipase Reactor
The synthesis of citronellyl butyrate by direct esterification reaction catalyzed by immobilized lipase from Candida rugosa was studied in a continuous packed bed reactor using n-hexane as organic solvent. Parameters such as residence time, temperature, and pH were examined. The optimum conversion was obtained at a flow rate of 1 ml/min (residence time 8 min), temperature of 50 °C, and pH 7.5. ...
متن کاملKinetic Study of Ethyl Hexanoate Synthesis Using Surface Coated Lipase from Candida Rugosa
Kinetics of lipase-catalyzed esterification of hexanoic acid and ethyl alcohol using the solvent-free system, surface coated lipase from Candida rugosa, had been studied. The effect of various parameters such as reaction time, reaction temperature, reaction kinetics, water removal and feasibility of solvent-free system had been focused. Candida Rugosa lipase was more effective than other li...
متن کاملOptimization of Candida rugosa lipase immobilization parameters on magnetic silica aerogel using adsorption method
Magnetic silica aerogel in hydrophobic and hydrophilic forms were used as support to immobilize Candida rugosa lipase by adsorption method. Response surface methodology (RSM) was employed to study the effects of the three most important immobilization parameters, namely enzyme/support ratio (0.3-0.5, w/w), immobilization time (60-120 min) and alcohol percentage (20-40, %v/v) on the specific act...
متن کاملOptimization 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 کاملPhytochemical Analysis and in Vitro Antimicrobial Activity of Calotropis Gigantea, Lawsonia Inermis and Trigonella Foecum- Graecum
Objective: The aim of the present study was to screen phytochemicals and antimicrobial activities of the extracts of three medicinal plants viz. Calotropis gigantea, Lawsonia inermis and Trigonella foenum-graecum. Methods: The methanolic extracts of the three plants were tested against clinical isolates of five bacterial strains (Staphylococcus aureus, Bacillus cereus, Methicillin Resistant Sta...
