Enzymatic Interesterification of Crude Palm Oil with Methyl acetate: Effect of Pre-treatment, Enzyme’s Dosage and Stability

Bulletin of Chemical Reaction Engineering & Catalysis, 2023
In the present study, biodiesel was produced via the enzymatic interesterification of Crude Palm Oil (CPO) and methyl acetate within ultrasonic condition. In contrast to alcohol, methyl acetate as an acyl acceptor does not inhibit lipase activity and can

Improving Lipase Activity by Immobilization and Post-immobilization Strategies

, 2013
One important parameter for the application of lipase catalysts in chemical industries is the specific activity displayed towards natural or unnatural substrates. Different strategies to enhance the lipase activity have been described. The immobilization of lipases on hydrophobic supports by interfacial adsorption at low ionic strength permitted the ...

Lipase immobilization and production of fatty acid methyl esters from canola oil using immobilized lipase

Biomass and Bioenergy, 2011
Abstract Lipase enzyme from Aspergillus oryzae (EC 3.1.1.3) was immobilized onto a micro porous polymeric matrix which contains aldehyde functional groups and methyl esters of long chain fatty acids (biodiesel) were synthesized by transesterification of crude canola oil using immobilized lipase.

Comparative performance of microbial lipases immobilized on magnetic polysiloxane polyvinyl alcohol particles

Brazilian Archives of Biology and Technology, 2008
Microbial lipase from Mucor miehei and Candida rugosa were immobilized by covalent binding onto magnetized polysiloxane polyvinyl alcohol particles (POS-PVA). The resulting immobilized derivatives were evaluated in aqueous solution (olive oil hydrolysis)
